I have seen the cables Cat 3 - Cat 7 classified as UTP cables. But now I've learnt that there are some UTP cables that have shielding. Shouldn't cable types like CAT 6 with "each wire pair wrapped in foil and foil to cover the wire pair bundles..." be also classed as STP?

Please help clarify.

I am fairly sure you will get a 4 paragraph answer to your question but it boils down to: They come in both flavors. Normally if you walk into a Best Buy and buy a Cat6 cable its going to be UTP its just a lot more common. But you can get Cat6 in STP too.

Hope this helps thumbup.gif

Technically, there are no shielded UTP cables. There are shielded twisted pair cables (STP), and unshielded twisted pair cables (UTP), but shielded UTP (SUTP??) is an oxymoron. Sometimes the term UTP is used as shorthand for just twisted pair. It's not correct, but there you go. Technically, barbed wire qualifies as UTP as well, but I'm not sure what Category rating it might have.
