Customer is interested in (future) 100Mb over UTP. Questions wether Level 5 is absolutely a requirement or will Level 4 be ok? Could someone comment on this and/or point me to a primer on Level 4 and Level 5 cable technology? Thanks, LH

Is the customer pushing for category 4 cable? The standard will require category 5 cable for the general case (i.e. works without thinking to 100m meters). Shorter distances may be able to use category 4 cable, but the proof of this (radiated emissions performance in particular) has yet to be seen. Gioven the current info, it will be difficult to guarantee that all category 4 runs will be usable in the future. If they want to wait a few months until the standard becomes firm, they could also do that. Try Data Communications December issuse (I think). They had a story on cabling. You can also order a copy of EIA/TIA Technical Service Bulletin 36 by calling Global Engineering Documents at 1.800.854.7179 This document has the techniocal details of the different UTP cables. | |||||

If you have a choice of which wire to run, the only answer I can see that makes sense is to go category 5. That way you maximize your chances at no significant cost increase. paul |
