 110 to RJ45 patch cords
We did a job using Cat. 5e 568B jacks on workstation end, Cat. 5e wire, terminated on 110 closet end. Now we have 110 to RJ45 patch cords in the closet to go to the active equipment. I think they are 568B, the strange thing is to get things wired right we had to terminate the cable to the workstation orange T&R, blue T&R, green T&R, brown T&R. Why can't we terminate using the correct color code?

Dear Dan,

I suspect that your 110 to RJ cords may actually be wired to T568A. You should be able to see the colors of the conductors at the RJ end to verify this. If the green pair is on one end then it is T568A, if Orange then it is T568B.

If you have at least an 8 pair tester, you can verify it with the cord plugged in so you have an RJ45 at both ends to plug in.
