And that's easier than terminating fiber?

Since the IEEE has a committee (802.3bq) that is establishing the electrical parameters for 25GBase-T and 40GBase-T, the emerging specifications all point to shielded, 2 pair, 22 gauge cable which can be terminated on RJ-45 or the Siemon TERA connectors. Right now, this is all in development.

Here's The Link

One thing that stands out, for me, is that this is being specifically developed for Edge data centers and the distance limitation is 30 meters and that is ONLY if the committees can develop a working standard. Just because there is an IEEE committee and a TIA/EIA standard, that doesn't mean any of this will actually be deployed as it is being discussed now. There are too many variables that have not been addressed, yet.

IEEE recognizes 2,000 MHz data rates as being practical over fiber not copper. The 802.3bq committee is trying to resolve the copper 2,000 MHz limitations and the resulting connector problems.

Cha Ching!

I hear the sound of money rolling in, as all the yahoos insist on the latest and greatest!

Two questions for all of you .

Who has installed Cat 7 ? Was it needed ?

Who needs?

• steam engines
• telegraph
• wireless telegraph
• radio
• television
• airplanes
• automobiles
• antibiotics
• inside plumbing
• jet planes
• flush toilets
• color television
• polaroid cameras
• vaccines
• Category 8 cabling

Since TIA/EIA never adopted the international Cat 7 standard, we have not had any requests to install, just a lot of IT weenies wanting to know when it's going to be available. My response, to them, is never.

The category was adopted in Europe but has not been formally set as a standard in the U.S. The category was in IEEE committee, however, the 802.3bq committee which is setting the electrical conformation codes for Cat 8 basically, negated the committee that had been considered for Cat 7.

The operative word is exactly what Silversam wrote: "Cha-Ching."

I'm a dreaded IT geek by trade. I always spec CAT5e unless the client specifies otherwise. I find it is still less expensive than CAT6 and easier to work with. It's plenty fine for 99% of the small businesses that I work with, now and into the future. Most of their apps are going to the "cloud" anyway, so even less data being transmitted back and forth. I personally don't see the reason to keep stringing copper along with new specs every few years. Just go fiber and be done with it. Then you just change out the optics on the end for whatever faster specs come out. Glass doesn't change too much.

There is no such thing as Cat7 in the states. The TIA skipped it.

Even the fiber specs have changed over the years. I used to run 62.5/125, but if you wanted to go to 10Gb or faster, then you would want OM3 50/125 fiber end to end instead.

Still after all these years nobody does fiber to the desktop because copper is still the cheaper, backwards compatible, and just as good for most applications.
