I have a client who has been experiencing a significant amount of performance issues in regards to their telemarketing floor. On my initial assessment, I found that where the ethernet is punched down, the last 1-2 feet of the cable jacket is stripped leaving a massive bunch of the individual pairs all bound together with no jacket protection. Basically, the guy who installed the cable stripped the ethernet where it enters the patch panel, leaving the remaining pairs bare all the way up to the punches.
I know that the jacket primarily protects the cable from physical and environmental damage, but with this amount of exposed wiring (48 punches = 384 pairs) in such a concentrated location, I'm wondering if the exposed pairs would have any effect on network performance? And if so, how would I go about testing it?
