Well...

Any type of modulated frequency carrying cable has a much larger capacity than a copper loop ever will. The problem is there are many more pieces of active electronics with RF/optical.

Copper loops are much more economical.

Cable telephony for instance is going to be interesting. We're going to be placing active VOIP boxes fairly soon. In some systems, they have taps that have access doors with 110 blocks in them, and that part takes care of dialtone off of the cable system.

Very interesting stuff.

Fiber is a great thing, it just sucks to splice. Some of the larger trunk fiber we use to feed remote headends is 144 strands plus. Takes over a day to splice the whole thing.

Give me a 25 pair 710 press any day.
