What Is Crossover Cable?

Crossover cable, as the name suggests, cross over or swap on its way when coming from one end to the other. Unlike patch cable, crossover cable uses two different wiring standards on both end: one end uses the T568A wiring standard, and the other end uses the T568B wiring standard. Both side (connector A and connector B) of crossover cable have wire arrangement with different color, and the wires that come out of the connector A should match the correct pin at the connector B. As shown in the following wiring scheme, you can see that Pin 1 on connector A goes to Pin 3 on connector B, pin 2 to pin 6, pin 3 to pin 1 and pin 6 to pin 2, etc. The crossover cables are mainly used for connecting two routers, computers, or hubs.
