What is the difference between 568A and 568B wiring standards?
The main difference between 568A and 568B wiring standards lies in the pinout configuration of the wires within the Ethernet cable. Both standards utilize eight wires, organized into four twisted pairs, but the arrangement of the color-coded wires differs. In 568A, the pairs are arranged with the green pair on pins 1 and 2, the orange pair on pins 3 and 6, while the blue and brown pairs occupy the remaining pins. In contrast, 568B has the orange pair on pins 1 and 2, the green pair on pins 3 and 6, and the configurations of the blue and brown pairs remain unchanged.
This difference may seem minor, but it is significant when it comes to compatibility and connectivity. Most networking equipment defaults to the 568B standard, making it the more commonly used wiring scheme in commercial and residential installations. However, 568A is recognized for being the preferred standard in government and educational institutions.
