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 I

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 inte

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

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 strengt

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 t

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. There is a high-density polyethylene cross isolation bracket in the middle of the cable to distinguish the four pairs of wires, which makes the balance performance of the pair more stable and can effectively prevent Perfo

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

Nowadays, many manufacturers produce more products. Some of them also produce power cables, HDMI cables, patch panels, etc., but are there any companies specializing in the production of Category 6 network cables, which only make finished network cables, and other products do not. The editor will take you to understand today that Shenzhen Kaiweier Electronics Co., Ltd. specializes in the production of super five network cables, super six network cables, 7 network cables, and 8 network cables. The product is single, focusing on product quality and customer satisfaction! Category 6 cables are definitely better than Category 5 cables. Category 5e cable (CAT5e): Category 5e has low attenuation, less crosstalk, and higher attenuation to crosstalk ratio (ACR) and signal-to-noise ratio (SNR), With smaller delay error, performance is greatly improved. Super Category 5 cable is mainly used for Gigabit Ethernet (1000Mbps). Super Category 6 or 6A (CAT6A): The transmission bandwidth of this type of product is between Category 6 and Category 7, and the transmission frequency is 500MHz. The transmission speed is 10Gbps, and the standard outer diameter is 6mm. Super Category 6 is also called 6A, which can support 10 Gigabit Internet access. At present, the maximum can reach 500MHZ, which is twice that of Category 6 network cables. At present, 6A is divided into two types: unshielded and shielded. Unshielded is similar to Category 6 cables in appearance. The details are more obvious. The 6A has a denser lay length and a thicker conductor. The most important thing is the outer sheath PVC. The traditional PVC is smooth, and the 6A adopts a gear-like cable groove shape. It can effectively change the enhanced signal to prevent the minimization of signal attenuation. There is also a shielded 6A network cable. This kind of shield uses a pair-to-pair shielding structure, which is very different from traditional shield

It`s already difficult for the 100M network to meet the requirements of some people. Gigabit In systems such as network engineering, a large number of gigabit network cables are used for wiring. Then the first choice of gigabit network cable: Category 6 network cable (CAT6) or Super Category 6 network The line (CAT6A) is also more popular. Kaiweier will introduce to you today what is the meaning of the "Super (A)" of CAT6A cable (CAT6A)? What's the difference with Category 6 network cable do not! 1. Appearance The Super Category 6 network cable will be thicker for two reasons, because CAT6A has two shielding layers, and the core will be thicker, while CAT6 has unique Special cross skeleton structure. Everyone knows that the thickness of the core is an important indicator that affects the transmission rate, and it is generally proportional. Whether it is six The high-quality core is made of oxygen-free copper, which also determines that the network cable can transmit data with low attenuation and high efficiency. Everyone The material of the core is judged by the color of the cross section of the core 2. Data Super Category 6 network cable CAT6A core: about 0.58mm, the highest speed can reach 10000Mbps, bandwidth: 500MHZ, network cable diameter is about 7.8mm; Category 6 network The CAT6 core of the cable is about 0.56mm, the highest speed can reach 1000Mbps, the bandwidth: 250MHZ, the diameter of the network cable is about 6.2mm; through the above comparison, it exceeds six Category 6 network cables directly outperform Category 6 network cables. 3. The price of Super Category 6 network cable Good products are not cheap, but the Super Category 6 network cable is more expensive than the Category 6. How you choose depends mainly on the network environment you are in. If it is a gigabit network, you can choose either Category 6 or Category 6. If it is a 1

Finished network cable wholesale, finished network cable specifications, finished network cable production Among the common network cables, the finished network cable is a network cable with a crystal plug, which can be used directly, called a jumper. The ordinary network cable consists of a box, and then cut it Made with crystal head, then, ①Why can't the general network cable have its own crystal head? ②Is the general network cable and jumper just the difference between whether there is a crystal plug or not? ③What is the difference between the general network cable and jumper use environment? 1. Appearance In addition to the difference between whether or not it comes with a crystal head, the identification of the network cable is also different. As we all know, the network cable is generally connected to the crystal according to the T568A and T568B standards. Header, since the jumper has been connected to the crystal head, it must be connected according to one of the connection methods, which is generally T568B standard, which is reflected in the logo of the jumper on. 2. Wire core The core of the network cable is the core, and the core is the true carrier of the transmission signal. The core of the jumper is generally 8 cores and 7 strands, that is, the jumper has 8 cores, each The root core is composed of 7 strands of thin wire cores. However, the general network cable has only one core per core. The signal transmitted by the network is also an electrical signal, and most of the electrical signal transmission is transmitted through the surface of the conductor. According to this principle, the transmission energy of the jumper is. The force is stronger than that of the general network cable. At the same time, the jumper's anti-interference ability will also be improved. 3. Network environment General network cables are commonly used in integra

CAT5e network cable, CAT5e network cable wholesale, supply CAT5e network cable, CAT5e network cable manufacturer, CAT5e national standard oxygen-free copper unshielded network cable is tested by Fluke, the implementation of standard specifications, the use of high- quality oxygen-free copper, 99.9% high purity, The resistance is small, about 100 meters is about 9.5 ohms, the network transmission can reach 120 meters, the digital high-definition monitoring transmission video signal can reach 150 meters, coaxial or analog monitoring... Category 6 network cable, Category 6 network jumper, Category 6 network jumper wholesale, CAT6 network cable Our factory specializes in the production of various specifications of Category 6 network cable, Category 6 network jumper, non-shielded Category 6 network jumper, Shield network jumper, color network jumper. Factory direct sales of six types of flat network cables 1-30 meters, six types of flat network cables, ultra-thin network cables, multi-color customization, six types of flat network cables Why should the network jumper be produced with No. 28/28AWG copper wire? In the past few years, some manufacturers have successively introduced 28 AWG jumpers, which have smaller diameters. It helps to improve air circulation around active equipment, and because it can relieve cable congestion and a smaller bending radius, it is conducive to easy cable management in high-density patch cord areas. Original machine pressing, unlike hand-made, there will be unstable pressure on the head, crystal head falling off, and the network cable cannot be in contact with the crystal. The machine suppressed the network cable will not hav

The network jumper cable is also called the finished network cable, which refers to the network cable with crystal plugs connected at both ends of the network cable. The injection molded short-meter finished network cable is often used for the connection between the host and the router; The network jumper is a core composed of multiple strands of thin copper wire conductors, which has good flexibility to ensure that the jumper is very convenient during use. The internal structure is 7 strands of copper wire, generally 7 * 0.08 / 7 * 0.1 / 7 * 0.12 / 7 * 0.16 / 7 * 0.20. Network jumpers are generally divided into Category 5, Category 6, Category 6, Category 7 and Category 8; Category 5 jumpers are generally used in 100M networks, and Category 6 jumpers are generally used in Gigabit networks and are compatible with 100M networks. For networks, when using Category 6 jumpers, switches and routers must be replaced with gigabit switches and routers to transmit gigabit networks. Category 6 is mainly used in gigabit networks. In terms of transmission frequency, it is also 200-250 MHz like Category 6 lines, and the maximum transmission speed can also reach 1 000 Mbps, but it is greatly improved in terms of crosstalk, attenuation and signal-to-noise ratio. Category 7 is a shielded twisted pair cable, so its transmission frequency can reach at least 500 MHz, which is more than twice that of Category 6 and Super Category 6, and the transmission rate can reach 10 Gbps. Category 8 network cable is the latest generation of double-shielded (SFTP) network jumpers. It has two wire pairs, can support 2000MHz bandwidth, and the transmission rate is up to 40Gb/s, but its maximum transmission distance is only 30m, so it is generally used The connection of servers, switches, patch panels and other equipment in short-distance data centers.

As an indispensable supporting role in network transmission-network cable! The network cable plays an important role. Without it, there will be no transmission between networks, and there will be no transmission between all networks. It may be a bit absolute, but it is the case. The wide use and scope of the network cable affects thousands of computers and TVs... As for the network cable, many people think that it can be used as long as it is plugged in. It is this kind of thinking that sometimes turns your high-level network cable into a low-level network cable, which makes you spend a lot of money without enjoying the same effect. Today, I will introduce the network cable. What is the difference between the shielded network cable and the unshielded network cable in the network cable. ? What are the ways to shield the network cable? From the perspective of whether the network cable is shielded or not, there are two types of network cables, shielded and unshielded, but there are obvious differences in structure. The unshielded network cable only has a shielding layer on the outside, and the four pairs of twisted network cables inside have no shielding layer and are only separated and fixed by a cross-shaped frame in the middle. In addition to the shielding layer on the outside of the shielded network cable, the internal four pairs of twisted network cables are also shielded by aluminum foil. The drain wire reduces both external interference and external radiation interference. The role of the former is equivalent to reducing the bit error rate of data transmission and improving the stability of transmission performance; the role of the latter is directly manifested in reducing interference to other network cables and improving the confidentiality of transmitted data. Users who have certain requirements for data transmission security can consider choosing it. For working environments with harsh electromagnetic environments, shielded wires

Does the speed of the network have anything to do with the network cable? It does matter. As the transmission medium of network data, the network cable is directly related to the network speed. If the network speed is compared to a car, then the network cable is equivalent to the road under the car. The highway is definitely faster than the muddy road. If the network cable is used incorrectly, it will have a great impact on our network speed. The network cables we commonly use in our lives generally include Category 5, Category 6, Category 6, Category 7, and Category 8, which correspond to different transmissions. Speed (for details, please refer to the "Relationship between Network Jumper Types and Transmission Rate"). The network cable must match the network. If you are an ordinary network, you can choose a super five network cable, if it is a Gigabit Ethernet application system, you must choose a six network cable, otherwise the unmatched network cable will greatly reduce the network speed and stability; If you are in a place where there is strong electromagnetic interference, you must choose a twisted pair network cable with shielding effect, because the shielded cable can effectively shield the interference through certain technologies and improve the network stability. If you have high network requirements, the performance selection of the network cable is very important. It is specifically manifested in the aspects of network cable anti-interference ability, transmission delay, and bit error rate. ? In conclusion, as a necessary material for a network topology, a network cable can also be said to be a bridge for network transmission, so the choice of network cable has a lot to do with the speed of the network.

Nowadays, the network cable arowana in the computer market is mixed, with various colors and skins, making people in the industry dumbfounded. Here are some basic knowledge about network cables for your reference: Cables mainly include: twisted pair (also known as network cable), optical fiber and coaxial cable (earlier products, now rarely seen and used). Among the three, coaxial cable is gradually eliminated by the market due to its relatively high price and general performance; optical fiber has very good performance, but the price is too high and installation is more difficult. Generally, it is only used when all indicators require relatively high performance. In high network environments, home networks rarely have this application; twisted-pair cables are widely used in wired networks because of their low price, simple installation method, and good and stable performance. Twisted wire cables are generally divided into 8 categories: Category 1 line is mainly used for voice transmission; Because the transmission frequency of category 2 line is only 1MHZ, it is mainly used in the old token network; Category 3 cables are mainly used for 10BASE-T networks; Category 4 line token network and 10BASE-T/100BASE-T network; Category 5 cable has a transmission rate of 100MHz and is used in 100BASE-T and 10BASE-T networks. It is the most commonly used Ethernet cable; Super Category 5 cable is mainly used for Gigabit Ethernet (1000Mbps); The transmission frequency of Category 6 lines is 1MHz~250MHz, which is suitable for networks with a transmission rate higher than 1Gbps; Category 7 cable is the latest unshielded twisted pair cable with a transmission frequency of at least 500+MHz and a transmission rate of 10+Gbps. In addition, twisted pair cables are divided into two types: shielded and unshielded. Shie

On the one hand, the poor RJ45 connector is not easy to be clamped, on the other hand, the copper sheet is easy to disconnect from the network cable. Identification method: At first glance, look at the color of the RJ45 plug, the color of the high-quality crystal head is clear and clear, no variegated, no stray particles; Secondly, look at the thickness of the crystal head, the high-quality crystal head is thicker and uniform than the inferior crystal head, and the edges and corners are distinct; Three smells, smell the crystal head, high-quality crystal head has no odor, no peculiar smell, no strange smell, no smell; Four pressures, the elasticity of the crystal head is pressed, the high-quality crystal head is flexible, and the inferior crystal head is weak; Five, the sound of the crystal head, the high-quality crystal head sounds crisp, and the catch behind it is even more obvious. In fact, the quality of the network cable and the network head cannot be ignored. When the quality of the network cable is not good, signal interruption is prone to occur.

Low smoke zero halogen, abbreviated as LSZH, LSOH, LSFH and OHLS, refers to the material of the outer skin of the network cable. In the material classification of wire sheath in the wire and cable industry, the low-smoke halogen-free network cable sheath is composed of thermoplastic or thermosetting that emits low smoke when heated and does not contain halogen. Most of the network wire coating is composed of polyethylene, polyvinyl chloride or thermoplastic polyurethane. If it catches fire, chlorinated plastic will release toxic hydrogen chloride, and if it encounters water, it will produce hydrochloric acid. The low-smoke halogen-free materials will not release hydrogen halides or other acids during fire. Low-smoke halogen-free materials can reduce the toxic and corrosive gases produced when they burn. In poorly ventilated environments such as airplanes, train cars, or ships, low-smoke and halogen-free network cables are often used. Low-smoke and halogen-free materials are also commonly used in the railway industry, because there are high-voltage lines under the railway or signal lines that transmit train positions. The use of low-smoke halogen-free materials also reduces the accumulation of toxic gases when the circuit is damaged due to fire or short circuit. Like in the railway industry or the shipbuilding industry, one of the most important requirements is to protect personnel and equipment from toxic and corrosive gases. In these occasions, low-smoke and halogen-free materials are required to be used in the outer layer of the wires and cables. One of the selling points of low-smoke and halogen-free network cables is that few companies have deliberately emphasized low-smoke and halogen-free, unless Party A and the design unit explicitly require it. Mainly because of price factor considerations. Some small local factories do not produce low-smoke halogen-free cables.

The current wire market is flooded with low-quality and low-quality wiring products, which are difficult for ordinary consumers to distinguish. The cost of copper core accounts for between 75% and 85% of the cost of the entire network cable, and the most serious cutting edge is also the copper core. The wire diameter shrinks and the wire length shrinks, using recycled copper, copper clad aluminum, copper clad steel, etc. It plays a decisive role in the quality of the network cable. Once corners are cut, the performance will be greatly reduced. Therefore, no matter how good the performance of switches and routers, and how high the broadband line rate is, once the wiring quality fails, the entire network performance will fall short. In-wall installation, once the quality of the network cable is found to be inadequate, it may even destroy the entire decoration for maintenance. Buy high-quality network cables! Xiao Bian is here, give you a few tips! Four steps to identify the quality of the network cable 1. Wire core First, the transmission quality of the copper core network cable is the best. The quality of the copper core determines the transmission performance of the network cable. The higher the purity and thicker the copper, the higher the conductivity and the smaller the signal transmission attenuation. The copper wire with thick wire diameter, luster, softness and toughness is a good copper wire, and the core of the poor network wire is copper clad steel, copper clad aluminum, etc. Identification method: The most direct method is weighing. Whether it is shrinking wire diameter, shrinking wire length, or cutting corners such as recycling copper, copper-clad aluminum, and copper-clad steel, it will directly lead to a reduction in the number of grams of the network cable. The editor gives a comparison table of the grams of pure copper, copper-clad steel, and copper-clad aluminum cables:

The difference between Category 6 cable and Category 7 cable is mainly reflected in the following points: 1. Broadband and transmission Category 6 network cables support broadband 250Mhz and 1000BAST-TX transmission, while Category 7 network cables can support 600Mhz and 10Gbps transmission. 2. Wire structure Category 6 network cables can use unshielded twisted pair cables 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. 3. Application areas Category 7 wires are widely used in indoor horizontal wiring, shielded computer rooms and confidential network wiring, and the shielding effect is far better than Category 6 wires. The cabling performance of Category 7 network cable is improved significantly than Category 6 network cable, so its medium transmission capacity and attenuation level are almost equal to optical fiber performance. 4. They also differ greatly in their ability to connect to hardware. Category 7 network cable requires its connector to provide at least 60DB of comprehensive near-end crosstalk when it reaches 600 MHz. Category 6 network cable should not exceed Gigabit speed when it is in use. 5. Conductor size Category 6 wires can be used as 24AWG (7/0.20), 26AWG (7/0.16), 28AWG (7/0.12) conductors, and Category 7 wires are mainly used as 26AWG (7/0.16) and

Outdoor waterproof network cables are the best. Outdoor waterproof network cables are different from indoor cables in two points. Compared with the indoor network cable, the outer skin of the waterproof network cable is thicker and has a PE sheath layer inside. The main function is to be waterproof and sunscreen, tensile and compressive. It is a water-blocking network cable for outdoor wiring. Divided into unshielded network cable and shielded network cable. The indoor network cable has only a single layer of wire skin. In order to adapt to the indoor wiring, the indoor network cable is relatively soft. Indoor network cables are not as thick as outdoor waterproof cables, and there is no double-layer cable skin of outdoor waterproof cables, so they cannot play a good role in waterproof and sunscreen outdoors. If the indoor network cable is to be used outdoors, the risk is relatively high. The outdoor network cable has a thick outer skin, which is not easy to damage the outer skin during the outdoor wiring process. In order to maintain the flexibility of the indoor wiring to a greater extent, the indoor network cable should be protected against the outer skin of the indoor network cable when the wiring is piped. Especially when pulling the cable, do not use too much force to easily damage the core. If it is a better quality network cable, such as all-copper, oxygen-free copper network cable can be used for a long time, but it will inevitably be dropped, and wind, rain, and direct sunlight may cause damage to the network cable sheath. The result of unstable transmission speed. The outdoor wiring environment is often more difficult than indoor wiring. It is generally recommended not to use indoor network cables for outdoor wiring. In addition to being used outdoors, outdoor waterproof network cables can also be used indoors. Outdoor waterproof network cables can be used in places with heavy humidity and dampness

The principle of network twisted pair The network twisted pair is formed by a pair of mutually insulated metal wires twisted, which can not only resist a part of electromagnetic wave interference from the outside, but also reduce the mutual interference between multiple pairs of twisted wires. The two insulated wires are twisted together, and the interference signal acts on the two wires that are twisted together. The common mode signal can be eliminated in the differential circuit of the received signal to extract the useful signal. In a casing, different wire pairs have different twisting lengths. Generally speaking, the twisting length is within 38.1mm~140mm, twisted in a counterclockwise direction, and the twisting length of adjacent wire pairs is within 12.7mm. . The length of a twisting cycle of a twisted pair is called the pitch. The smaller the pitch (the denser the twisted wire), the stronger the anti-interference ability. Network twisted pair is divided into shielded twisted pair and unshielded twisted pair. 1. Unshielded network twisted pair It is a data transmission line consisting of four pairs of transmission lines of different colors, which are widely used in Ethernet circuits and telephone lines. The unshielded network twisted pair has an unshielded jacket, a small diameter, which saves occupied space and low cost; it is light in weight, easy to bend, and easy to install; it has the advantages of independence and flexibility. In the integrated wiring system, unshielded network twisted pair is widely used. 2. Shielded network twisted pair It is a copper twisted pair widely used for data transmission. In terms of physical structure, shielded network twisted pair cables have more full shielding layer and/or pair shielding layer than unshielded network twisted pair cables. Through shielding, attenuation and noise are reduced, thereby providing cleaner electronic signals. And longer cable lengths.
