I’m making a renovation of my apartment and I’ve been putting CAT6 u/FTP cable because the cables run together with the power ones. All the ETH cables go from all the rooms to a server closet. I think I have made a mistake doing that, as the keystone jacks I’ve purchased are not shielded. I noticed that the cable I’ve installed (alongside with all FTP cables I guess) has a ground wire, and I’m not sure if that’s supposed to be grounded at both ends or not.
Did I made a mistake? Is it possible (or a good idea?) to ground the wire at just one end? Am I deploying interference in the lines while doing that?
Grounding at one end should be better than no ground. AI says that grounding both ends is better. I try to do both ends on things that really need the ground.
In analog audio we would commonly only ground (shield) one end to try and prevent ground loops (difference in potential causing buzz). Some think this same applies to ethernet, but again the above.
Grounded (shielded) Cat6 cable should be used in environments with high electromagnetic interference (EMI) to help mitigate data corruption and signal degradation but are not really needed in most home environments. I doubt it’s a big deal to run it and not ground it.
