Not to confuse things, but my understanding was that corrosion would be a problem but only if the wire was corroded when you hooked it up. The wire will corrode over time but only in the parts exposed to the air -- the part which actually makes contact normally stays shiny.

As to why cable quality makes a difference in enterprise networking, my 2 cents would be that (a) the distances are much longer, (b) the signals are digital and extremely high frequency, (c) the differences between cheap cables and crappy cables tend to be in termination and twist consistency, not in the wire itself.

Oh yeah, and (d) there are a bazillion cables so if 0.01% have problems you still spend half your life troubleshooting ;\)
