RJ45 Connector
This connector RJ45 is available in two standards i.e. T568A and T568B. each of these works as pin IN and pin Out for ethernet cable to perform data transfer. the only difference between these two cables is the wiring of green and orange pairs.
RJ45 cable Pin Out color code T568A:
T568A is a commonly used pinout standard for ethernet cables. The highlight of this standard is that it is backward compatible with one-pair as well as two-pair USOC (Universal service ordering code).
Here is the color code table for the T568A standard:
Pin | Wire Color | Signal | Description |
---|---|---|---|
1 | white/Green | TX1+ | Transmit + |
2 | Green | TX1- | Transmit – |
3 | White/Orange | RX+ | Receive + |
4 | Blue | TX2+ | Bi-Directional Transmit + |
5 | White/Blue | TX2- | Bi-Directional Transmit – |
6 | Orange | RX- | Receive – |
7 | White/Brown | TX3+ | Bi-Directional Transmit + |
8 | Brown | TX3- | Bi-Directional Transmit – |
RJ45 cable Pin Out color code T568B:
This standard gives better protection from noise, It also isolates the signal more effectively as compared to T568A. It is only backward compatible with a one-pair USOC wiring scheme.
Here is the color code table for the T568B standard:
Pin | Wire color | Signal | Description |
---|---|---|---|
1 | White/Orange | TX1+ | Transmit + |
2 | Orange | TX1- | Transmit – |
3 | White/Green | RX+ | Receive + |
4 | Blue | TX2+ | Bi-Directional Transmit + |
5 | White/Blue | TX2- | Bi-Directional Transmit – |
6 | Green | RX- | Receive – |
7 | White/Brown | TX3+ | Bi-Directional Transmit + |
8 | Brown | TX3- | Bi-Directional Transmit – |
RJ45 Color Code
Pre-requisites: RJ Full Form
RJ45 is a well-known ethernet connectivity connector that allows users to connect through wired internet. there are other ports also which do the same, but RJ45 is widely used and most common in wired internet connection interfaces. It is an ethernet cable consisting of 8 wires(4 pairs of wires). These cables follow a specific color code with respect to the arrangements of the wires.
