Remembering the Cat5 Color Scheme
Posted November 16, 2008 at 02:11am in Network
For many years I never had to crimp cable, I had done it before, but never enough to bother remembering the coloring scheme. You have two choices T568A and T568B, the only difference between the two is that the green is swapped with the orange. Looking at the colors didn’t help me to remember it the first day I had to do a bunch of cables I just kept saying it in my head as I did it and it was very effective.
T568B: T568A:
White Orange White Green
Orange Green
White Green White Orange
Blue Blue
White Blue White Blue
Green Orange
White Brown White Brown
Brown Brown
When you make a crossover cable one end is T568A and the other is T568B. So just say those in your head while you crimp a few cables and you won’t forget it.
If you are making a rollover cable crimp on end and then prepare the other end, but before you put it in the ice cube flip it and then crimp.
