RJ45 Pinout Diagram, Colour Code, Wiring Diagram(cat 6,7,5e)

Hey, in this article we are going to see RJ45 Pinout Diagram and its terminal identification. Here, you can also see the RJ45 connector pin diagram and its connection for a crossover cable. RJ45 is an 8 pin connector that is used to connect computers and other networking devices to a Local Area Network(LAN). The full form of RJ45 is Registered Jack - 45. Actually, the RJ45 jack is originally designed for the telephone communication system but nowadays it is used for most of the networking communication systems.

Connection and Wiring Diagram of RJ45 for Crossover Cable

A crossover cable is used to connect two network devices having different RJ45 connectors. Generally, a cross over cable has both RJ45 Jacks, T-568A and T-568B it's both ends. Here, you can see the RJ45 wiring connection of a crossover cable.

For crossover cable connection at both ends, different connectors are connected. Here in the above diagram left side T-568A and right side T-568B is connected. You can know the function and color codes from the below table.

RJ 45 Pin	End 1 T-568A Color Codes	Function/Signal	End 2 T-568B Color Codes
1	White/Green	Data Transmit+	White/Orange
2	Green	Data Transmit-	Orange
3	White/Orange	Data Receive+	White/Green
4	Blue	Unused	Blue
5	White/Blue	Unused	White/Blue
6	Orange	Data Receive-	Green
