      For newer cable types, like cat 7, unshielded don't exist anymore as they are all shielded.

      CAT 7 is UTP. That CAT system is a designation of unshielded.

        From what I've seen only residential and small office installations run unshielded. Enterprise runs shielded and fiber.

        Never seen an enterprise run STP. Someone, somewhere does, but even in 2000 we were using fiber anytime UTP couldn't handle the interference in the enterprise. Every enterprise I've seen since 2000 was UTP for last "mile" and fiber in the long runs.

          I'm seeing a lot of shielded cable used in AP installations in new construction. The architect/engineers are requiring it and calling for 2 cables per AP. I don't feel its necessary but they won't allow any deviations from their plans.

            I wonder if this is a UK thing? I've definitely not hear anything like that around here.

              @Dashrender No. I'm in Texas. I've had multiple different architectural firms require this in new schools and other commercial buildings. Its never on the normal data drops or for cameras, etc. Only on AP locations.

                that's even more stupid! All those cables likely run through the same space.. yet somehow the APs are special? is that because they are fully expected to be POE and perhaps Texas has passed new laws surrounding usable levels of power?

                  @Dashrender My opinion is that the contractors charge more for for shielded cable drops therefore the architect makes more money. Yes, they are in the same cable trays and same j-hooks. They don't require shielded patch cords though. It all comes down to money.

                      Sounds like maybe one regional architect that is all screwed up?

                          Yup, now THAT is more of what I would expect.

                            I work with a few enterprises on a regular basis. Global 500 companies. None of them use unshielded cables.

                            They commonly use air blown single mode fiber anywhere you have some distance (100m) and shielded copper to the network devices. Now, this is for the campus network, not in the datacenter.

                            That said, it's what I've seen. But none of these companies have just a sales office.

                              You are mistaken Scott. Cat7 have individually shielded pairs. And usually a shield around that as well. So S/FTP (or U/FTP with just shielded pairs).

                                @Pete-S You are correct, I forgot CAT7 wasn't a real thing and is de facto STP not UTP, but uses a UTP designation for marketing purposes. That's probably why the UTP council doesn't recognize the whole family of 7 and 8 branded things. It's really crappy that they gave it a fake UTP designation just to be tricky. Argh.

                                    The shielding on CAT7 allows for longer twists, making it not as hard to work with as you might think.

                                      The twists aren't the annoying part. Trying to line up the tiny wires just right and clip the end of the plastic spacer. With CAT7 you have to deal with 5 layers of shielding instead of a spacer, and make sure the grounding wire is connected to the ground loop. No thank you, pre-terminated cable sounds like so much less work.

                                            In one of the companies that I worked, they have an "Initial Test" for any Engenier;

                                            They ask you, Are you an Engenier?, then do a Patch cord, here are the tools, make 1 with B Standard.

                                            That is the way to show that you are a good engenier... jajaja
