What Is a Crossover Cable?
The so-called "cross line" refers to the use of 568A standard at one end and the 568B standard at the other end; the non-cross line, or "straight-through line", refers to the use of the same standard at both ends. Crossover cables are generally used to implement the same type of equipment, such as hub-to-hub, hub-to-switch, router-to-router, switch-to-switch, or PC-to-PC connection.

- Crossover and non-crossover, the network cables used are the same, but the order is different when the head is pressed.

- Standard 568A: green white-1, green-2, orange white-3, blue-4, blue white-5, orange-6, brown white-7, brown-8.
- Standard 568B: orange white-1, orange-2, green white-3, blue-4, blue white-5, green-6, brown white-7, brown-8
- Generally, the same equipment is connected using crossover wires. However, if there is a "UPLINK" interface on the lower-end device, you can use a straight-through cable to connect to the upper-end device through the "UPLINK" interface.
- In addition, some new devices now have a port recognition function that can automatically identify whether it is a parallel line or a cross line, then it does not matter.
