Ahh, you're talking about stranded wire vs. solid core. Either one can be
certified CAT-5, but be sure that the connectors are for stranded wire. Most
are for solid wire, and there is a difference.

I've still never seen shielded CAT-5 before. I'm not saying it doesn't
exist, but be sure that the wire actually is CAT-5, and not CAT-3 or CAT-4.

Thanks Mike
 The wire is going in a machine shop.
 Mike I might be a little confused, (please correct me if I am wrong.) When
I say twisted, the cables are definently twisted around each other. The
copper wire inside is not twisted and is solid, is this Cat4? Also the Wire
that I have seen that claims to be shielded is coated in a foil type
substance with a bare wire running on the outside of it. Of course this is
all incased in you typical blue (or color of choice).
 The reason we worry about using "shielded" is that that we don't want to be
losing any data do to RF while it is running through the shop.
 Conduit would be about the same price to run with labor. As the so called
shielded wire.
Thank you again for you input.

As far as shielded Cat-5? I've never seen such a thing. There was a shielded
twisted pair that IBM used for token-ring, but that's Cat-4. Cat-4 is NOT
rated for 100mbps
Shielded Pros: Less outside interference in extremely noisy (electrical)
areas.
Unshielded Pros: 100mbps, much cheaper, resistant to electrical noise in all
but the worst environments when properly installed.
Use Cat-5 unless you're wiring a machine shop. If you're wiring a machine
shop, run Cat-5 in metal conduit.

 Hello everybody,
I was wondering the best place to buy shielded cat5 non twisted. I am
looking for around 2000ft.
 What are the pros to using shielded compared to non shielded?
