 Cat6 patch cords on cat5e installation, performance?
Hi, I've heard that using cat6 patch cords in a Cat5e structure environment can cause performance issues, is this correct? Thanks.

Dear Peter,

There is a slight chance that you may experience a return loss problem due to copper gauge change (24 AWG for CAT5E vs. 22AWG or 23AWG for CAT6), but I have never heard of anyone reporting this problem in real life.

It is obviously not going to work in reverse: CAT5E patch cord WILL degrade CAT6 performance of a cabling channel.
