I am installing an 802.3 campus network "backbone" that will use unshielded
twisted pair extensively within buildings.  The buildings sizes are such
that 100 meters doesn't quite reach from a central point to the most
distant lab/office in most buildings.  125 or 150 meters would.

What cable is available that is suitable for this length of run?  I need
cable that is described by the manufacturer (or "certified") to meet
10baseT specs out to this distance.  And I need it to be available in
100-pair cables.

I know about AT&T 2601A, which appears to be great and appears to work
well beyond 150 meters.  But it is only available in 4-pair sheaths so I
would end up with literally hundreds of these sheaths in many wiring
closets which isn't practical.  Also, it is very expensive.

Is there a 100-pair Hitachi cable of this type?
