We're about to rewire our office with a high-grade, shielded Cat6 cable that is supposed to support 10gig up to 55 meters (yes, I know there's no guarantee since there's no ratified standard yet). Our hope is that this high-grade wire will eliminate the need to do another network rewire for at least another 10-15 years. But there's a good chance that our server room may move from it's current location in the next couple of years. We could always use feeder cables to extend all the cable runs from the old server room to the new, but my question is, should we?
If we hope to someday run 10 gig over this copper, will a properly-done feeder cable be as good as a single unbroken run of the same cable over the same length? Do I run the risk of performance loss, increased exposure to EMI, or any other problems by using feeder cable in this scenario, or would I need to do another complete rewire to get the cable integrity I'd need for10gig? I realize I'm trying to predict the future of a technology that barely even exists today, but I'm hoping someone with particular expertise or experience in this area can tell me, on a gut level, what they think. I'd like to make the choices now that stand the best chance of serving us well for the future. In case it matters, we'll be running PoE over this wire today, and I can't image that 10gig networks won't try to do the same thing.
All comments appreciated, and thanks in advance.
