NETWORK CABLE

The best network cable is essential for connecting to the LAN. The common network cables in the LAN are mainly twisted pair, coaxial cable, and optical network cable manufacturer. Twisted pair is a data transmission line composed of many pairs of wires. It is characterized by its low price, so it is widely used, such as our common telephone line. It is used to connect to the RJ45 crystal head. It is divided into STP and UTP. We usually use UTP. There are two standards for twisted pair termination: T568A and T568B, and there are two main methods for connecting twisted pairs: straight-through cable and crossover cable. The two ends of the crystal head of the straight-through cable follow the T568B standard. Each line of the twisted pair has one-to-one correspondence at both ends, and the same color is consistent in the corresponding slots of the crystal heads at both ends. It is mainly used in the switch (or hub) Uplink port to connect to the switch (or hub) common port or switch common port to the computer network card. The end of the crystal head of the crossover cable follows 568A, while the other end uses the 568B standard, that is, the 1 and 2 of the A crystal head correspond to the 3, 6 of the B crystal head, and the 3 and 6 of the A crystal head correspond to the 1 of the B crystal head. 2, it is mainly used in the switch (or hub) common port to connect to the switch (or hub) common port or network card to the network card. When the horizontal line is terminated in the integrated wiring project, GB 50312 accepts T568B or T568A, but it is not allowed to install at the same time, usually terminated by T568B.
