Well, they quote distances over CAT6 but not CAT7 cable... Wonder why not. I have an interest in this, as its what was installed when our ship was built. Uses slightly different connectors called GG45, but they're backwards compatible with RJ-45.

I am SO glad I ignored ALL unsolicited advice to just install Cat5e instead of Cat6 in our new offices ("Why the hell do you need cat6?!"). We have a gigabit setup currently, moving around lots of large video files, and we can never have a fast enough network... fibre is too expensive and tricky for us - at least I won't have to disruptively rip out our copper when the day comes to upgrade networking equipment..
