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 | |||||
