The corresponding line sequence from pin 1 to pin 8 is:

T568A: white-green, green, white-orange, blue, white-blue, orange, white-brown, brown.

T568B: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown.

There is no substantial difference between the two world standards, only the difference in color. It is necessary to pay attention to the need to ensure when connecting two RJ crystal heads: pin 1 and pin 2 are a winding pair, pin 3 and 6 are a winding pair Yes, pin 4 and 5 are a winding pair, and pin 7 and 8 are a winding pair. In the same general wiring system project, only one connection standard can be selected. TIA/EIA-568-B standards are generally used in the production of connecting wires, sockets, and distribution frames. Otherwise, they should be clearly marked.

The RJ module is an important socket in the connector

The common RJ module is a kind of connector in the wiring system, and the connector is composed of a plug and a socket. The connector composed of these two elements is connected between the wires to realize the electrical continuity of the wires. The RJ module is an important socket in the connector.
