Will this ethernet "splitter" work satisfactorily?

[Bryan O'Neal]

How well did it work?  I was thinking about this just the other day.  I
have two CAT6 cables and jacks in one cube.  In that cube I have a
device requiring 3 of the four pairs and two devices requiring only 2
pairs.  I thought about just re-punching on both ends to split the
pairs, but not being very good with CAT6 and not having a high end
tester, I felt I would end up destroying my lovely tested GIG-E
connection. Since I plan on actually utilizing it in the next two years
I really did not want to do that, and I am just too lazy to run a cable
and make it look pretty.

This doesn't solve the originally posted problem, since using it still
requires a switch, but once you understand what it does, it makes a lot
of sense.

It doesn't splice two connections onto one.  Since 100bT only needs two
twisted pairs and a cat-5 cable has 4 pairs, a cat-5 cable has enough
wires to support two independent 100bT connections.  You put one of
these
"splitters" on each end of a cat 5 cable, and now it operates like two
independent cables.  We used these regularly at Motorola where we needed
an extra network connection in a cubicle, but didn't want to pull an
extra
cat-5 cable.  It won't work for gig-E because a single gig-E connection
uses all 4 pairs of the cable.
