Industrial automation refers to the introduction of intelligent equipment and automation technology to enable autonomous control and intelligent operation of all aspects of the production process, thereby improving production efficiency, reduce personnel costs and improve product quality. As an important part of data transmission lines, industrial network cables play a very important role in industrial automation. The following will introduce how to efficiently use industrial network cables to promote the development of industrial automation from three aspects. 1 . Ensure the stable quality of industrial network cables. As a key component of data transmission, industrial network cables must ensure the stability and reliability of their quality. Therefore, it is very necessary to use industrial-grade network cables in industrial automation. Industrial-grade network cables have the characteristics of high anti-interference ability, long life, stable transmission performance, etc., and can adapt to harsh industrial environments and long-term and high-intensity work. In addition, in order to ensure the stable quality of industrial network cables, you need to pay attention to the following points during use. First, avoid placing industrial network cables too close to power lines or high-power equipment to avoid interference. Secondly, industrial network cables must be regularly inspected and maintained to ensure that their appearance is intact and that the interfaces are free of oxidation and other problems. Finally, pay attention to protecting the connection part of the industrial network cable and avoid frequent plugging, unplugging and bending, so as not to affect the transmission effect. 2 . Build a stable industrial network In order to achieve the goal of industrial automation, it is essential to build a stable and reliable industrial network. In industrial networks, industrial network cables are an important part that play a bridge role and are responsible for data transmission. Therefore, building a stable industrial network requires the following points. First of all, network cables must be arranged reasonably to ensure connectivity between various devices and the stability of data transmission. During the wiring process, avoid excessively long lines and excessive connection points to reduce transmission delays and signal losses. Secondly, pay attention to the purchase and configuration of network equipment. Appropriate network equipment such as switches and routers can provide a stable network environment and ensure fast data transmission and reliable connections. In addition, regular network inspections and maintenance must be carried out to discover and resolve network faults to ensure network stability. At the same time, network security protection must be carried out to protect the security of industrial networks and the confidentiality of data. 3 . Give full play to the functions of industrial network cables Industrial network cables are not only lines used to transmit data, but can also use other functions to improve the level of industrial automation. Here are a few typical examples. First, industrial network cables can be used to connect sensors and controllers to achieve real-time data collection and signal transmission. In this way, real-time monitoring and adjustment of the production process can be achieved, improving production efficiency and reducing resource consumption. Secondly, each device and the industrial control host can be connected through industrial network cables to achieve collaborative control and information sharing between devices. Through the connection of industrial network cables, different devices can communicate with each other and work together to improve the efficiency and stability of the entire production line. In addition, industrial network cables can also be connected to cloud platforms to achieve remote monitoring and management. Through the connection of industrial network cables, various data and equipment status at the production site can be transmitted to the cloud platform in real time, enabling remote monitoring and intelligent management of the production line. In practical applications, real-time communication systems, video surveillance systems, etc. can also be built through industrial network cables to further improve production efficiency and enhance production safety. To sum up, in order to efficiently use industrial network cables to promote the development of industrial automation, we must first ensure the stable quality of industrial network cables, secondly build a stable and reliable industrial network, and finally give full play to the functions of industrial network cables. Through effective application and management, industrial network cables will become an important driving force for industrial automation, helping companies improve production efficiency, reduce costs, and improve product quality.

In industrial networks, it is very important to improve network performance. Category 5e industrial network cable is a commonly used type of network cable. By tuning this Network cables can effectively improve network performance. The following will introduce some methods for tuning Cat5e industrial network cables. First, confirm that the Cat5e industrial network cable complies with relevant specifications. Category 5e industrial network cable is a standardized network cable type with specific specifications Require. Make sure that the network cable used meets these specifications to ensure that its performance can be fully utilized. Secondly, pay attention to the wiring method of Cat5e industrial network cable. Reasonable wiring methods can effectively reduce signal interference and loss and improve the stability of network transmission. Qualitativeness and speed. You should avoid placing network cables together with high interference sources such as power cords and cables. Try to use torque-balanced wiring to twist the network cables and connect them to each other. Interleave to reduce mutual interference between signals. In addition, pay attention to the length of Cat5e industrial network cable. If the length of the network cable is too long, it will cause signal attenuation, thus affecting the transmission speed and stability of the network. one Generally speaking, the maximum allowable length of Cat5e industrial network cable is 100 meters. Exceeding this length will cause greater signal loss. Therefore, when wiring, you should Properly plan the length of network cables to minimize the use of additional connectors and extension cords. In addition, it is also very important to maintain a good connection status of Cat5e industrial network cables. Check the quality of the network cable connector and make sure it is installed firmly and reliably. Use high-quality network cable sockets and network cable crystal heads to provide stable connections and good transmission performance. At the same time, promptly clean up the dust and debris near the connection points objects to avoid poor wiring or signal interference. When tuning Cat5e industrial network cables, you can also further improve network performance through LAN optimization. Use appropriate switches, routers, and other Network equipment to provide higher bandwidth and more stable network connections. Optimize the settings and parameters of network equipment and rationally plan the network topology to improve data transmission efficiency. In addition, you can also consider using network acceleration technology to further improve the performance of Cat5e industrial network cables. For example, using bandwidth optimization techniques can effectively Improve network transmission speed and reduce data delay. Using data compression technology can reduce the bandwidth requirements for data transmission and improve network throughput. In short, optimizing Cat5e industrial network cables to improve performance requires comprehensive consideration from multiple aspects. Reasonable wiring, control the length of network cables, and maintain good connections Connection status, optimizing LAN settings and using network acceleration technology are all important methods. By taking these measures, the performance of Cat5e industrial network cables can be improved. can further improve the working efficiency of industrial networks.

Many friends know that good network cables need to be tested, but they don`t know how to distinguish them. Today Xiaokai will help you understand: How to distinguish the quality of network cables through the Fluke test? How to distinguish the quality of network jumpers? Fluke is a professional testing tool. Fluke testing usually refers to the American Fluke tester that performs network cable testing and produces a test report. Now it is also widely used for the acceptance of integrated wiring weak current projects, and its test results are recognized by people from all walks of life at home and abroad. Fluke's test projects include link testing, channel testing, and unit testing. What do these three types of tests refer to? Xiao Kai, editor of Shenzhen Kaiwell Electronics Co., Ltd., is here to share with you: 1. Channel test (channel): This project is often used as a network jumper test project and over-channel test network cable. The network cable tested by this project can meet most network needs and is suitable for small enterprise networks and home wiring connections for short-distance transmission. 2. Link test (link): It mainly tests whether the engineering network cable (boxed network cable) meets the standard, and the over-link test network cable. Through the test project target network cable, it can be suitable for long-distance outdoor connections and ensure the transmission effect. 3. Unit test (patch cord): Also known as jumper test, single-unit test network cable is mainly a test item for network jumpers. It is a high-level test item. The test performance includes long use time, more stable performance, and no packet loss or data loss. In contrast, network cables that have passed unit testing have better performance and are suitable for application environments with high performance requirements, such as medium and large data centers or brand data centers. To sum up, whether it is a home network, an enterprise network or a digital-centric network, in the face of the growing number of digital streams and multimedia services, large-capacity and high-speed networks continue to expand, and the requirements for network cables will only become higher and higher. Therefore, In the long run, choosing a good quality network cable is imperative. According to the application field, for home networks and small business networks, the network connection structure is simple and the transmission speed and performance requirements are not high. Just choose a network cable that has passed the Fluke channel test. If you use a poor-quality network cable, it will cause serious consequences such as packet loss, lagging, network failure, and even paralysis. Therefore, it is best to test the network cable through a Fluke unit. Customers who need such products, please feel free to contact me.

To meet the patch cord performance specified by the TIA/EIA 568B.2 standard, high-quality raw materials must be used. The patch cord cable materials include two parts: the cable and the RJ45 connector: 1. Network cable and patch cord The conductor is made of oxygen-free round copper rod, the resistivity is less than 0.017241; the insulation is made of HDPE, and the better brands are UCC3364, etc.; Generally, the matching patch cord and the on-site production patch cord can meet the requirements in terms of materials, but the network patch cord purchased in the market is difficult to guarantee. The material cost of some inferior jumpers on the market is very low, and the performance can only ensure conduction. Mainly reflected as: Conductor: The patch cord purchased in the market may be made of aluminum, or it may be made of inferior copper. Such conductors have high resistivity and poor ductility; Insulation: The better one may use the general HDPE insulating material, and the poor one may use the recycled material. The dielectric constant of this kind of material is large and unstable, and the elongation is small. In addition to having little electrical performance, this type of patch cord also suffers from short lifespan and poor reliability. 2. Network cable RJ45 connector The metal sheet substrate of RJ45 connector (crystal head) is mainly made of phosphor bronze and nickel-plated and then gold-plated. Generally, the thickness of gold-plated from 1u to 50u, and the thickness of the gold-plated layer of six types of crystal heads is generally 50u" (1.27μm). The performance does not deteriorate when the connector is plugged and unplugged more than 750 times; the plastic shell is PC, which conforms to UL-94-V0, and the RJ45 shrapnel is required to be plugged and unplugged more than 750 times without breaking. The metal sheet, gold-plated layer and plastic shell material of the matching brand finished patch cord RJ45 all tested in the factory according to the standard, which can ensure the mechanical and electrical performance requirements of the product. If the RJ45 used in the on-site production patch cord comes from the original product, the quality can also be guaranteed. If the RJ45 is purchased in the market, the mechanical, electrical and fire performance of the material is difficult to guarantee.

There are three main differences between them: 1. Different definitions The network cable is a small switch that controls the current flow on the circuit board. Its function is to adjust the on-off relationship of different electrical signals on the device, and to adjust the working state of the device, such as determining the mainboard voltage, the master-slave relationship of the driver, and so on. The lan cable belongs to Twisted pair (UTP) is one of the most commonly used transmission media in integrated wiring projects. It is composed of two copper wires with an insulating protective layer. Two insulated copper wires are twisted together at a certain density, and the radio waves radiated by each wire during transmission will be offset by the radio waves emitted by the other wire, effectively reducing the degree of signal interference. 2. Different roles. The function of the ethernet cable is to adjust the on-off relationship of different electrical signals on the device, and to adjust the working status of the device, such as determining the mainboard voltage, the master-slave relationship of the driver, and so on. When the network cable clip is put on two cable posts at the same time, it means that the two cable posts are connected. If only one or no cable posts are put on, it means it is disconnected. Lan cable are generally used more on engineering wiring and are indispensable for connecting to local area networks. 3. Different types. Network cable include computer board card cable, optical fiber jumpers, ethernet cable and so on. The lan cable is twisted pair.

Let's take a look at the connection method of the crystal head of the network cable RJ45 interface network cable crystal plug connection method is not difficult, simple and not easy, the materials needed are network cable and crystal plug, let's talk about how to connect the network cable crystal plug in detail, and then let the editor Lead you to take a look. In the first step, remove the jumper cable sleeve from the end. The second step is to remove the cross-shaped skeleton on the jumper. The third step is to arrange the wires from left to right according to the 568B or 568A standard. In the fourth step, after the wires have been trimmed, put them on top of the wire breaker inside the crystal head, paying attention to the order in which the wires are interspersed. Pull down the cable divider inside the crystal head along the wire until there is no unlocking button, and then remove the excess cable in front. The fifth step is to put the repaired wires inside the outer layer of the crystal head, paying attention to the correct orientation. The sixth step is to use a crimping tool to compact the finished crystal head. The above is the connection method of our jumper crystal head. We can see that with the development of science and technology, the network cable crystal head has played an important role in our daily life. When we connect the crystal head, we must follow the connection method, so as to be able to exert its maximum effect. Hope it could help everyone.

The general situation of Super Category 6 network cables can be simply divided into Category 6 unshielded twisted pair (UTP-Unshield+Twisted+Pair) and Category 6 shielded twisted pair (STP-+Shield+Twisted+Pair). With the development of the network and the increase in transmission requirements, various network cable manufacturers produce various shielded cables according to their needs. The classification of super six types of unshielded and shielded cables is as follows: U/UTP is commonly referred to as UTP twisted pair, unshielded twisted pair The total shielding layer of F/UTP is aluminum foil shielding, shielded twisted-pair wire without pair shielding layer U/FTP has no overall shielding layer, and the wire pair shielding is a shielded twisted pair shielded by aluminum foil The overall shielding layer of SF/UTP is a double shield of wire mesh + aluminum foil, and the pair of double shielded twisted-pair wires without shielding S/FTP total shielding layer is silk screen, wire pair shielding is double shielded twisted pair shielded by aluminum foil 1. F/UTP shielded twisted pair aluminum foil total shielded twisted pair (F/UTP) is the most traditional shielded twisted pair, mainly used to isolate the 8-core twisted pair from the external electromagnetic field. Interference has no effect. The F/UTP twisted pair is wrapped with a layer of aluminum foil on the outer layer of the 8-core twisted pair. That is, there is a layer of aluminum foil outside the 8 core wires and inside the sheath, and a grounding wire is laid on the conductive surface of the aluminum foil. F/UTP twisted pair is mainly used for Category 5 and Super Category 5. F/UTP shielded twisted pair is also used in Category 6 and has the following engineering characteristics: 2. The shielding layer of U/FTP shielded twisted pair + wire pair shielded twisted pair (U/FTP) is also composed of aluminum foil and grounding wire, the difference is: the aluminum foil layer is divided into 4 pieces, each of which wraps 4 wire pairs , Cut off the electromagnetic interference path between each pair. Therefore, in addition to resisting external electromagnetic interference, it can also resist electromagnetic interference (crosstalk) between pairs. The U/FTP pair shielded twisted pair cable comes from Category 7 twisted pair, currently it is mainly used for Category 6 shielded twisted pair cable, Category 6 double shielded network cable, and Category 5 shielded twisted pair cable. Pay attention to the following issues during construction: the aluminum foil layer should be terminated with the ground wire to the shielding layer of the shielding module; the shielding layer should form a 360-degree contact with the shielding layer of the module; to prevent the shielding twisted pair The core wire and shielding layer should be stressed at the sheath of the twisted pair. Use the nylon cable tie attached to the shielding module to fix the twisted pair with the metal bracket at the back of the module; do not leave it on the shielding layer. gap. 3. The total shielding layer of SF/UTP shielded twisted pair + SF/UTP shielded twisted pair is aluminum foil + copper wire mesh, it does not need a ground wire as a drain wire: copper wire mesh has good toughness and is not easy to break, so It itself can be used as a drainage line for the aluminum foil layer. In case the aluminum foil layer breaks, the wire mesh will continue to connect the aluminum foil layer. The SF/UTP twisted pair is on the 4 twisted pairs, and there is no separate shielding layer. Therefore, it is a shielded twisted pair with only a shielded layer. SF/UTP twisted pair cables are mainly used for Category 5 and Category 5, and are also used in Category 6 shielded/Category 6 shielded network cables.

Small network cables are also asked by universities. You can`t ignore them. Professional network cable manufacturer Kewell tells you that network cables have transmission distances. For example, in the integrated wiring specification, the horizontal wiring must not exceed 90 meters, and the total link length must not exceed One hundred meters, that is, one hundred meters is a limit for wired Ethernet, and this limit is the length of the link from the network card to the hub device. Twisted pair has a transmission distance of "one hundred meters" that is "insurmountable", whether it is a Category 3 twisted pair with a transmission rate of 10 meters, or a Category 5 twisted pair with a transmission rate of 100 meters, or even a transmission rate of one kilometer. The effective transmission distance is 100 meters. The physical factors of the twisted pair largely determine the quality of the network cable. Inferior network cables often use unqualified twisted pair core wire winding methods, and cheap metal The core wire achieves the purpose of cutting corners, and this irresponsible behavior directly aggravates the interference of the network signal in the network cable, so that the effective transmission distance of the network cable is far less than 100 meters, and it will also affect the stability of the network transmission and the network cable. Service life etc. When using PoE power supply, why does it stipulate that the length of the network cable shall not exceed 100 meters? However, in actual construction, in order to ensure the quality of the project, it is generally 80-90 meters. Please note that the transmission distance here refers to the rate, such as 100M. If the rate is reduced to 10M, the transmission distance can usually be extended to 150-200 meters, so the PoE power transmission distance is not determined by PoE technology. It is determined by the type and quality of the network cable. Although in actual construction, a better quality network cable can break the 100-meter distance limit and the equipment can work normally, this approach is not recommended. Because some potential problems do not appear immediately, but slowly appear over time, which will cause follow-up maintenance problems. In simple cases, such as bandwidth upgrades, devices that can work normally at distances of more than 100 meters will not work properly after the network speed is greatly increased. How did the network cable transmit the distance of 100 meters? What caused the 100-meter transmission distance limit for twisted-pair cables? It is necessary to delve into the deep physical principles of twisted pair. The transmission of the network is actually the transmission of the network signal on the twisted pair. As an electronic signal, when it is transmitted in the twisted pair, it must be affected by resistance and capacitance, which leads to the attenuation and distortion of the network signal. When the signal attenuation or distortion reaches a certain level, it will affect the effective and stable transmission of the signal. Therefore, the twisted pair cable has a transmission distance limit, so how do you calculate the upper limit of 100 meters? Category 5 UTP and Category 5 UTP are mainly for computer network services. According to the 100Base-TX regulations of Fast Ethernet, the communication rate is 100mbps. There are devices at both ends of a link. These two devices may send data at the same time, causing conflicts. At this time, the conflict domain is 2. Data packets will be lost due to conflicts. In order to avoid packet loss caused by conflicts, Ethernet uses conflict detection and back-off retransmission technology. In order to back off and retransmit, it must be ensured that one end can detect the conflict before transmitting a data packet. The influence of cable type and quality on transmission distance + what we are talking about is the three types of lines, five types of lines, seven types of lines... Cables are twisted tighter and tighter, and there are more and more spacers between pairs (cross frame, aluminum foil, Mylar, drain wire, copper wire mesh), and the frequency ranges from 16MHz to 100MHz, 250MHz, 500MHz, 600MHz and many more. +When the frequency increases, the crosstalk phenomenon becomes more and more serious. This requires increasing the diameter of the copper wire, increasing the torque of the cable, increasing the cross frame to separate the cables, increasing the thickness of the outer sheath or increasing the shielding layer Wait for various production processes to solve the increasingly difficult crosstalk problem.It has to be said that crosstalk makes the cable structure more and more complicated. Category 5 cables are common standard cables on the market, but the quality of different cable manufacturers differs greatly. Which cable manufacturer is better? It must be ranked by professional network cable manufacturers. The network cable produced by Kaiweier is good, with 99.99% oxygen-free copper conductors. Under the trend of price wars, many manufacturers use copper-clad iron and copper-clad copper wires in order to reduce costs. The replacement of steel leads to a decrease in the transmission distance of the network cable, and even network instability, packet loss, etc., and equipment manufacturers are often in the dark, which is really wrong. Therefore, if PoE is to be effective, a good quality network cable must be used. Large losses affect the overall quality of the project. Look for network cable, look for Shenzhen Kingwire Electronics Co., Ltd., guarantee quality and quantity!

A large amount of network equipment is generally placed in a data center, so safety is very important. In addition, fire prevention is particularly prominent in potential safety hazards, and the equipment in the data center keeps running and radiates a lot of heat, which can easily cause fires. Let's take a look at the flame retardant material! 1. CMX LSZH. This is the lowest grade among low smoke zero halogen(LSZH) . There is a certain open flame when the fire is burned, but the fire is not very large, and the price is relatively cheap. 2. CM LSZH. This material has relatively few contrasts. The first is that the effect is not very significant, and there is a small open flame when burned. 3. CMR LSZH. This material is suitable for comparison, and it is mainly suitable for straight use. This material is also loved by everyone. This is reflected in the fact that when it is burned, it will calm down after a while. The fine smoke has a significant effect and is currently favored by domestic and foreign customers. 4. CMP LSZH. This material is the highest grade. It is mainly used in forced ventilation environments. It embodies smoke-free and no open flames. It has a very good effect. The price is more expensive. There are not many domestic applications. It is mainly used in developed countries. It can be seen that there are certain differences in the application scenarios of different flame-retardant network cables.If you need it, you can directly purchase it on the Kingwire B2B platform. The authenticity is guaranteed and the price is low. Hope the above content is helpful to you!

Home broadband is getting cheaper and more affordable, even when it's bundled with a mobile phone plan. Although 100 megabit broadband download speed is fast, but also have someone say that their home network clearly signed is 100 megabit, download speed has been unable to go up. In addition to the cat and routing, there is another thing to match the speed of the Internet, and that is the old cable. Someone might ask, isn't the network cable universal? Do you need a special network cable? The answer is yes, there are types of network cables, also divided into high and low, the following to talk to you about this humble network cable, it is likely to limit the speed of your home. At present, the most common and commonly used ones are cat5e network cable,cat6 network cable, cat6a network cable, cat7 network cable and cat8 network cable. Category 5 are the lines that were used more often before, and their transmission rate is only 100Mbps, which is suitable for the network environment of 100 megabits or less. In the days of dial-up phone lines, this was the type of cable used. Although now to the fiber optic era, but there are some cat5 on the market, mostly used for monitoring this kind of high-speed transmission wire does not need to use more scenes. The outer skin of the cat5 is generally marked with the words "CAT.5", which is easier to identify. Cat5e network cable is the mainstream product at present, it has small attenuation, strong anti-interference ability, transmission rate can reach 1000Mbps, is the replacement of class 5 line, more than 100 mbit/s optical fiber network environment are used cat5e. If you're using 100 megabits or more, check your cable for "CAT.5e." Finished network cable, more than cat5 of network cable If there is no logo, there are two ways to identify. One is the appearance. The network cable of super 5 classes will be thicker than the network cable cat5e. The second is to cut the skin, super five types of network cable is twisted pair Then is the cat6, there are gigabit networking requirements or friends must use such a network cable, the transmission frequency of the six types of line is higher than the previous five and super five types of line, comprehensive attenuation and anti-interference performance are significantly better than the first two types of network cable, transmission rate up to 1Gbps. It also has its own "CAT.6" written on its skin. Six lines Furthermore, it is the cat6, it is the improved version of the six class line, in addition to the progress in the transmission performance, the transmission rate reached 10Gbps. There is "cat.6a" on the outer skin of the super six line, and there is also a cross skeleton inside which the four pairs of twisted pairs are separated. It also comes in a double-shielded version, but the typical home user doesn't need any of these cables, and they cost almost twice as much as the type 6 ones. There is a category of seven lines, it is mainly used for ten gigabit network, transmission rate up to 10Gbps, it has a shielding layer for each pair of lines, four pairs of lines together and have a public shielding layer, so the appearance is much thicker than the common network cable. Its anti-interference performance and transmission performance are much better than that of super class six lines. This kind of network cable is about half more expensive than the more than six types, and our general users do not use it. In short, if the home broadband in more than 100 megabits, it is recommended that you choose super five lines or six lines; If you need to pull the network cable is very long or in the decoration to prepare wiring, it is recommended to choose six types of line, after all, buried line to change is also troublesome. Then when you buy network cables, find professional production network cable manufacturers, so that the quality and delivery can also be guaranteed. Super five types of network cable/six types of network cable/seven types of network cable kewel has production, welcome to consult and buy!

What is difference between ordinary and flame-retardant PVC? First, you may need to know whether your own PVC products are hard or soft. Rigid PVC: Since polyvinyl is a hard-to-burn material, hard PVC is inherently flame-retardant, while soft PVC is different, because soft PVC needs to be added with oily plasticizer , Let the material soften, the flame retardant effect of the material will be weakened. Everyone knows that oily substances will burn in fire. At this time, if you want to make soft pvc achieve the flame retardant V0 effect, you need to add a flame retardant to the material. , Then the difference between ordinary and flame-retardant pvc is because of the flame retardant added by the latter, so the density and cost of flame-retardant pvc will slightly increase, while the transparency and tensile strength will be slightly reduced. Enhancement of combustion performance. In other words, if the hardness of soft pvc is softer, then if you need to achieve better flame retardant effect, you need to add more flame retardants, then the cost will rise greatly, which is why some pvc prices are so expensive The reason is up. Hope the above content is helpful to you!

Network Cable: A medium used to carry information from one Network device (such as a computer) to another. It is the basic building block of a Network. In our common local area network, the use of network cable is also a variety of types, there are cat5e network cable, cat6 network cable, cat7 network cable and cat8 network cable. In general, a typical LAN does not use many different kinds of cables to connect network devices. In a large network or wide area network, different types of cable are used to connect different types of networks together. In many kinds of network cable, the specific network cable should be selected according to the network structure, network structure standard and transmission speed. The cable produced by the network cable manufacturer is Twisted Pair, which can be divided into two types: Shelded Twisted Pair (STP/SSTP/SFTP) and Unshelded Twisted Pair (UTP). The so-called shielding refers to the outside of the signal line inside the network cable is wrapped in a layer of metal mesh or aluminum foil, outside the shielding layer is the insulation skin, the shielding layer can effectively isolate the interference of external electromagnetic signals. UTP is a kind of network cable that can be used with high frequency in local area network. The wire is wrapped in a plastic insulated sheath with eight signal wires, two of which are wound together to form a total of four pairs, hence the name twisted-pair. So the transmission speed test of network cable is an effective means to identify the quality of network cable. In order to be closer to the actual use environment and reduce external interference, the author suggests using the method of double machine direct connection. At the same time, in order to ensure the accuracy of the test, try to use good quality brand network card, to ensure that the test will not occur hardware bottleneck phenomenon; At the same time, it is also necessary to ensure that the computer system is clean, tidy and fast, otherwise the running speed of the computer itself will affect the transmission speed of the network cable. In addition, when connecting the network cable, try to use good quality crystal head, also want to ensure that the line head is done standard, only in this way can the influence of external factors on the transmission speed of the network cable be reduced to a relatively small degree. Network wire material is aluminum and oxygen - free copper. Super Class 5 Unshielded Twisted Pair is a kind of cable after some performance improvements of the existing five types of shielded Twisted Pair. Many performance parameters, such as near-end crosstalk, attenuation crosstalk ratio, return loss, etc., have been improved, but its transmission bandwidth is still 100MHz. Super Class 5 unshielded twisted pair wires can also provide transmission bandwidth of up to 1,000 Mb/s, but often require the support of expensive special equipment. Therefore, it is usually only used for 100Mb/s Fast Ethernet to connect the desktop switch to the computer. If you are not going to upgrade your network to Gigabit Ethernet at a later date, you might as well use Class 5 Twisted-Pair in horizontal wiring.

Network cable is essential for LAN connection.In the local area network common network cable mainly has the twisted pair, the coaxial cable, the optical cable three kinds.Twisted pair is a data transmission line composed of many pairs of wires.It is characterized by low price, so it is widely used, such as our common telephone line and so on.It is used to connect to the RJ45 connectors. Network cables are mostly used for the same potential and voltage transmission and for short-circuiting and connecting two wires.For precise voltage requirements, the voltage drop generated by a little metal jumper can also have a big impact on product performance. Network jumpers are also called finished network cables, which are classified into super five types of network jumpers, six types of network jumpers, seven types of network jumpers and eight types of network jumpers. The network cable is used for data transmission and connection to the local area network and for transmitting information within the network. There are two line sequences of network cable: T568A and T568B. Here, the line sequences of class B are used (white orange, orange, white green, blue, white blue, green, white brown, brown). First, use net pliers to peel off the outermost protective glue at one end of the network cable, revealing 8 copper wires with protective glue. Then, separate the tangled wires, straighten the copper wires with your fingers and arrange them in the B order (from left to right, white orange, orange, white green, blue, white blue, green, white brown, brown). Use net pliers to cut the ends of the wires flat One hand has been cut flat net wire, the other hand of the crystal head with the metal side facing yourself, along the wire inserted, and then use the net pliers to press down the copper crystal head Repeat the above three steps and press the other end of the net cable into the crystal head in the same line order Insert the two RJ45 heads of the finished network cable into the two network ports of the host end and the far end of the network cable tester respectively. Test whether the indicator lights of the host end and the far end are consistent. If they are consistent, the network cable has been completed. This connection method because there is no machine forming, so the use may be unstable, easy to loose, professional production of network cable manufacturers, can directly provide finished products, machine forming, convenient and durable.

The difference between Category 6 network cable and Category 7 network cable In modern life, each of us inevitably needs to go online, and to go online we need a network cable. There are also several types of network cables. Two of them are category 6 cables and category 7 cables. Many people don`t know the difference between these two types of cables. Let me explain it to you below. The composition of seven types of network cables: 4 pairs of core diameter 23AWG single strands of high-quality oxygen-free copper are used as conductors (the copper conductor is insulated with FMPE material), the wire pair and the cable are integrated with aluminum foil and the high-efficiency double shielding structure, the cross is isolated, and the transmission frequency is also extended to 600MHz. Category 7 network cable is an 8-core shielded cable, each pair has a shielding layer (usually a metal foil shielded Foil Shield), and then there is a shielding layer outside the 8 cores (usually a metal braided wire mesh shielded Braided Shield), The interface is the same as the current RJ-45. The scope of application of seven types of network cables: Widely used in indoor horizontal wiring, shielded computer room and confidential network wiring Seven types of shielded jumpers Multi-core bare copper flexible wire is used as the conductor, and the jumper has outstanding transmission performance, suitable for 10/100/1000/10GBASE-TX Ethernet data transmission; the overall aluminum foil of the cable is effectively shielded, and it is used in shielded wiring to prevent interference effect. 1. There are some differences in the broadband between the two. There is a term called the ratio of comprehensive attenuation to crosstalk. Both types of network cables provide such things. Category 6 cables provide no less than 200 MHz, while Category 7 cables can provide no less than 500 MHz. The former can provide a lot. At 250 MHz bandwidth, the latter can provide at least 600 MHz bandwidth. 2. The cabling performance of the Category 7 network cable is improved significantly than that of the Category 6 network cable, so its medium transmission capacity and attenuation level are almost equal to the performance of the optical fiber. 3. There are also differences in structure between the two. Category 6 network cables can use unshielded twisted pairs or shielded twisted pairs, but Category 7 network cables can only use shielded twisted pairs. One of the seven types of network cables is called a shielding layer. Every two wires form a pair, and then a shielding layer can be constructed. The four shielding layers are combined to form a common large shielding layer. 4. They also differ greatly in their ability to connect to hardware. The Category 7 network cable requires that its connector provide at least 60DB of integrated near-end crosstalk when it reaches 600 MHz. When the Category 6 network cable is in use, the network speed should not exceed one hundred megahertz. With the development of the information age, people's needs are also increasing. In the integrated wiring industry, there is a certain gap between Category 6 network cables, Category 7 network cables and optical fibers. In terms of the current consumer market level of the domestic wiring industry, For a long period of time, the seven-category network cable still meets people's demand for bandwidth. However, as data center technology and optical fiber supporting equipment are updated and upgraded, the competition between the seven types of network cables and optical fibers will continue to escalate.

It depends on what occasion you are using, it is good to be applicable. The flat network cable is flexible, suitable for short-distance connections and jumpers on the rack. Generally, there is no difference between the two lines of less than 20 meters. The flat cable is of soft material and good quality, and the maximum transmission speed is up to Gigabit/10 Gigabit. The seven types of flat network cable structure each pair of wire wrapped aluminum foil + ground wire. The round wire has strong anti-interference and is not beautiful. Used this kind of flat network cable, of course it is a flat one. The flat wire is generally just a short jumper. The round network cable is a standard twisted-pair cable with strong anti-interference ability and suitable for long-distance connections. The round wire is twisted, and the flat wire is straight. The rotary screen cable has strong anti-interference, and the signal is more stable and the delay is smaller during long-distance transmission. The high-end point of the round wire has a skeleton that is more resistant to breaking than the flat wire. 1. There is no substantial difference in actual use. 2. Different in appearance, the traditional network cable is 8 wires and no two are entangled with each other, which can have some interference shielding effects. Due to the structural constraints, the seven types of flat network cables can only be wrapped in aluminum foil for each pair of wires. Braided shield 3. It is more convenient for flat network cables to remake crystal heads. After all, they are all arranged in a row. Just peel off the outer cable. Normal network cables need to be arranged manually. 4. The flat network cable can be passed through a very thin gap, and the outer cover is very soft. Many Amazon network cables choose seven types of flat network cables. The traditional network cable can only be passed through a round hole. If the gap is too small, there is no way. 5. The price of flat cable is more favorable than the round price, and it is more affordable to buy a flat cable with a shorter meter. In summary, if you want to save money or wiring, round wire is the best choice. If you want to connect directly between devices for convenience, you can choose a flat cable. The international standards for network cables are only for box cables, so flat cables are non-standard parts. Therefore, when buying flat cables, you should buy flat cables produced by large manufacturers with good reputation.

From the appearance point of view, network cables are divided into round cables and flat cables. In normal life, we generally encounter round cables, and the amount of flat cables is relatively small. But the flat network cable also has its advantages, let's talk about its two major advantages below: 1. Volume advantage. The outer diameter of the six types of flat network cables is 1.5*6.0mm, and its thickness is only 1.5mm, which is only equivalent to the thickness of a one-yuan coin. It has a volume thickness of only 1.5mm and can be easily hidden in carpets, door cracks, and space-restricted machines; it can also walk along the wall in the bedroom and living room without affecting the appearance. Cost advantage. Flat network cables generally use 32AWG copper wires. Compared with round wires, the 23AWG copper wires of the six types of network cables can save a lot of copper. In the short-distance transmission of 30 meters, the performance of the flat cable is basically the same as that of the round cable. The advantage of flat cable using less copper is due to its flat design. Our ordinary round cable is 4 pairs of twisted pairs close together, so the 4 pairs of twisted pairs have a greater influence on each other in signal transmission, and the flat The network cable 4 pairs of twisted pairs are laid flat and have a certain distance between each other, so the twisted pair has less mutual influence when transmitting signals. Because of its flat design, the flat network cable can easily achieve the same performance as the round cable six types of network cables while using less copper. Of course, the flat network cable has the above two advantages, but also has its shortcomings. One is that its copper wire is small, the resistance is large, and the performance is not as good as the national standard round cable at a transmission distance of 30 meters away; the other is a flat network cable. It is relatively thin, and its tensile strength is not as good as a round wire. Super six types of flat cable, thin and simple, create a simple and comfortable indoor space, dexterous and delicate, and the transmission speed can reach 100MBPS, which is undoubtedly a treasure for small partners with network speed requirements. Benefit 2: Easy to install without fear of damage Due to the flat nature of the wire, we can easily hide the network cable under the carpet, and the flat setting can not be afraid of squeezing and stepping, and it can also easily pass through various corners. The flat super-category six network cable is more conducive to the wall It looks more comfortable. Benefit 3: Sophisticated workmanship and real materials Kingwire Super Category 6 network cable uses 8P8C gold-plated Pin needles to provide the best conduction effect and ensure unobstructed transmission. The connection between the cable and the crystal head is suppressed by the original machine to effectively prevent various problems such as the crystal head falling off.

Kingwires Super Category 6 flat network cable gives you a different comfortable experience and super-fast transmission. Consultation hotline: 15818652993

There is no difference between the connection method of the class unshielded network cable and the cat5e network cable, and the line sequence is basically no problem. There are two standard connection methods for network cables: 568A standard: green and white, green, orange and white, blue, blue and white, orange, brown and white, brown 568B standard: orange and white, orange, green and white, blue, blue and white, green, brown and white, brown The order of inserting the crystal head is: from left to right, in line order The biggest difference between Category 6 unshielded cables and Category 5 network cables is that there is a cross frame. When we connect the crystal head, after removing the outer skin, we need to sort the exposed white crosses and then sort the cores. Can use T568A/T568B line sequence for sorting In a wiring system, the wire sequence of the network cable should be standardized and unified, which is conducive to saving man-hours and multi-person wiring. If the network is blocked, it is easy to troubleshoot the situation. After sorting (T568B), the wire cores can be cut neatly. The outer skin of the network cable needs to be stuck into the crystal head. The crystal head is not easy to fall, and you can mark the position. The copper plate of the crystal head is facing upwards, the wire core is connected to the crystal head, and the crystal head is inserted into the cable clamp bayonet and pressed firmly. You will find that the six types of crystal heads are slightly different from the five types of crystal heads. The lines in the five types of crystal heads are lined up, and the lines of the six types of crystal heads are staggered up and down. At that time, because the five and six types of crystal heads were made by the RJ45 standard, the specifications and sizes were the same. However, the core of Category 6 wire is thicker than that of Category 5 wire (from Dr. Cable), so the core of Category 6 wire can be connected to the crystal head Staggering up and down can make the crystal head hole bigger.

Twisted pair (TP) is one of the most commonly used transmission media in integrated wiring projects. It is composed of two copper wires with an insulating protective layer. Twist two insulated copper wires to each other at a certain density, The radio waves radiated by each wire during transmission will be cancelled by the radio waves emitted by the other wire, effectively reducing the degree of signal interference. Twisted pairs in computer local area networks can be divided into two categories: unshielded twisted pair (UTP) and shielded twisted pair (STP): STP is wrapped with a layer of metal material to reduce radiation and prevent information from being eavesdropped on. At the same time, it has a higher data transmission rate, but the price is higher, and the installation is more complicated; UTP has no metal shielding material, only a layer of insulating rubber wrap, the price is relatively cheap, and the network is flexible. Except for some special occasions (Such as severe electromagnetic radiation, high requirements for transmission quality, etc.) In addition to using STP in wiring, we generally use UTP. The UTP currently in use can be divided into three types, four types, five types, super five types, six types, and super six types. The larger the type number, the newer the version, the more advanced the technology, the wider the bandwidth, and of course the more expensive the price. product structure: Conductor material/wire diameter: bare copper or stranded copper, ￠0.57±0.005mm (23AWG) Insulation material/wire diameter: polyethylene, ￠0.98mm±0.02mm Number of wire pairs: 4 pairs, two single-conductor double-twisted pairs form a pair.

Many small partners don`t know how to connect the switch to the network cable. As a professional network cable manufacturer, I will explain to you today: Switch means "switch" is a network device used for electrical (optical) signal forwarding. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The most common switch is an Ethernet switch. Other common ones are telephone voice switches, optical fiber switches, etc. VLAN is a virtual local area network. By dividing the local area network into virtual network VLAN network segments, network management and network security can be strengthened, and unnecessary data broadcasting can be controlled. Break the geographical restriction in the shared network, and divide the subnet according to the management function. Switches of different manufacturers have different support capabilities for VLANs, and the number of VLANs supported is also different Plug the network cable into the switch. If it is an ordinary switch, regardless of incoming and outgoing lines, just find an interface and plug it in. In order to facilitate differentiation and maintenance, it is recommended that one port be connected to the incoming line and the outgoing line to any remaining port. If it is a network management switch, it needs to be configured according to the configuration. For example, port 0/0/1 is VLAN1 and configured for PC1, then PC1 can only be connected to port 0/0/1. So there are 2 ways of connection 1. When using a crossover cable, connect to the "common ports" of two switches (this line is also used to connect two computers directly to Zhuan) 2. One end of the standard line is connected to the switch "Ordinary port", the other end is connected to the "cascade connection port" of another switch (this line is also used to connect the computer to the switch) -*- The usual "switches" have cascading ports. Mark "Up-link" or "X" on it (There are also some models, except for the "Grade Connection Port" which is blank, and the other models are all painted with "X") The suggestion is to use standard cables when the "switch" has a cascaded connection port. Because the "switch-computer" connection uses the same line, it is convenient for management and maintenance When you are really helpless and use the "crossover cable" to connect, be careful not to confuse it with the standard cable used by the "switch-computer" Shielded CAT5E cable installation component FTP (foil twisted pair) shielded patch cable is very suitable for environments where strong noise near wires may cause interference. Shielding can prevent electromagnetic interference and reduce crosstalk.
