Crimping on RJ-45s to solid conductor cable is unreliable and considered unprofessional.

Please log in for more thread options I was thinking of doing the same thing at home, skipping the patch panel mostly to not have the additional cost. However, since everyone seems to think that the RJ45 to keystone isn't a good idea, I'll go ahead and get a patch panel. The one question I have is, is there a preferred cable to use for this setup? I'm going with Cat5e, but am not sure about solid, UTP, shielded, plenum, etc. Any information would be most appreciated.

You can build a small patch-panel equivalent very inexpensively with a double-gange electrical box (cut out back) with two 6-keystone plates. > The one question I have is, is there a preferred cable to

Solid (to make punchdowns work), non-plenum (cheaper and fine for residential use in most places). UTP is fine, shielded is overkill unless you do a lot of arc welding. -- Robert | ||||||||||||||||||||||

Named after air handling plenum spaces that is common above suspended ceiling offices. Harder to work with. Solid works better with punchdown terminations, and is less expensive. this is what most folks use in the walls. Shielded is useful if you are in a RFI rich environment. Arc welders, radio transmission towers, thermoelectric welders and so on. --Dale | ||||||||||||||||||||||
