I purchased a tooless IDC Keystone Jack and it has 8 slots to fit the 4
pairs of twisted wire for the cat5. The cat5 cable that I'm using has an
extra bare wire, for ground possibly ??
Where would this bare wire go on the jack ?? I don't see an extra slot for
Are you sure the cable is labelled 'category 5'? Cat 5 is supposed to
be unshielded; there should be nothing like a foil or mesh wrapper
around the cable pairs. There are (or were) kinds of shielded twisted
pair that were used for other things (IBM token ring, for instance),
not 10/100baseT ethernet.
Are you sure it's a copper wire? Some cables have strands of
non-conductive fibre for strength, to decrease damage when the cable is
If it is shielded twisted pair, it may not work for ethernet. If it is
really cat 5 with an odd wire, then, well, I dunno. I'd leave it
Maybe you could post back with the exact brand of the cable and any
markings on it.
The bare wire is stranded steel and not copper. It also has a foil jacket
underneath the plastic covering.
Here's the info stamped on the cable: Belden Datatwist(R) Five 1624P ScTP
CMP Powersum Verified (UL) Catergory 5 E108998.
Hope this helps you...
It's Catagory 5E shielded (ScTP - "screened" twisted pair), plenum rated
(CMP). You would normally use it with a shielded keystone jack. You would
then use shielded patch cables, etc. The shield helps keep outside
interference from affecting the data. It's good quality cable, but
typically not needed in a home environment, and more expensive than the
standard Unshielded Twisted Pair (UTP).
If you purchased the wire and haven't used it, see if you can return it and
get UTP. If you can't return it, go ahead and use it and just ignore the
bare wire. In a commercial environment, with hundreds (or thousands) of
feet of wire, that's not a good idea since the unconnected shield can act as
an antenna, but for the distances you're working with in a home, it's not
going to be an issue.

Thanks for the come back ! This cable was given to me by a friend and I
already have it burried in conduit out to the workshop, about 200 feet
So replacing it would be a tremendous effort. I'll do what you suggested
and cut off the bare wire and go with the 4 twisted pairs.
This will be used for an Ethernet connection. I believe I failed to mention
that in my Original Post.
Thanks to all who replied.
