RJ45 Color Code - T568A and T568B

Here, in this article, we are going to see the RJ45 Color Code. RJ45 stands for Registered Jack 45. It is a standard physical connector used for connecting Ethernet networks. As we know RJ45 connectors are widely used in networking applications, including home and office networks, data centers, and various other Ethernet-based systems. So there is a huge demand for RJ45 installations. RJ45 color coding is very important because it helps to technicians that the network cables are wired properly by following a standardized pattern. The color coding is part of the TIA/EIA-568 standard, which specifies the arrangement of the wires within an Ethernet cable and the corresponding pin assignments in the connectors. There are two common wiring schemes: T568A and T568B.
