How do I color code my Ethernet cable?

Patch Cable Color Standards

  1. Grey – used for standard ethernet connections.
  2. Green – used for crossover ethernet connections.
  3. Yellow – used for POE connections.
  4. Orange – used for analog non-ethernet connections.
  5. Purple – used for digital non-ethernet connections.
  6. Blue – used for terminal server connections.

How do I know if my cable is 568A or 568B?

If you are looking at a patch cord the easiest way to tell which standard you have is to look at the first two pins, if they are green, it is T568A, and if they are orange, you have T568B.

Where is 568B used?

U.S. Government regulations require the use of the preferred 568A standard for wiring installed under federal contracts. However, N-Tron adopted the 568B standard since it is the most widely used in the industry today. It matches the older AT 258A colour code. It is also approved by the ANSI/TIA/EIA standard.

What is the difference between T568A and T568B wiring?

The only difference between T568A and T568B is that the orange and green pairs are interchanged. T568A wiring pattern is recognized as the preferred wiring pattern for this standard because it provides backward compatibility to both one pair and two pair USOC wiring schemes.

How do I know if my cable is 568a or 568B?

What happens if you connect T568A to T568B?

split pairs which cause big problems with high speed transmission. Note that the only difference between T568A and T568B is the reversal of pairs 2 and 3 – it’s only a color code change, but if you mix up the two on each ends of a cable you will have a wiremap problem.
