Analysis of Class B Wiring Sequence of Network Cables

　　The wiring sequence of network cable type B (also known as T568B standard) is: white orange, orange, white green, blue, white blue, green, white brown, brown. This line sequence is usually used to make parallel network cables or standard network cables for connecting network devices such as computers, switches, routers, etc. When wiring, it is necessary to ensure that the crystal heads at both ends of the network cable are crimped in this order to ensure normal communication of the network.

　　More specifically, you can follow these steps for wiring:

　　Open the cable sheath to reveal the 8 colored cables inside.

　　Arrange the network cables in the order of white orange, orange, white green, blue, white blue, green, white brown and brown.

　　Using tools such as net pliers, press the arranged net wires into the corresponding slots of the crystal head in sequence.

　　After the crimping is completed, check whether the crystal head is firm and whether the wiring sequence is correct.

　　It is important to note that while most modern devices can adapt to different types of network cables, in some cases, such as when connecting older devices or special network devices, wiring may be required in a specific wiring sequence. Therefore, it is best to confirm the requirements and compatibility of the device before wiring.

　　In addition, in addition to class B line sequences, there are also class A line sequences (also known as the T568A standard), which are: white-green, green, white-orange, blue, white-blue, orange, white-brown, brown. In certain cases, such as when making crossed lines, class A line sequences may be used. But in most cases, class B line sequences are more commonly used.
