net backbone over cat 5 cable

what is the opperational distance of cat 5 cable the gigabit version?could the esb use this cable to connect households to there new backbone [ the cable would only run 5 or 10km] or would it be possible to use this over longer distances instead of fiber?

I don't know what the capabilities of CAT 5 / 6 are, but I suspect under 100 metres. However, seeing as you are running the cables on pylons / wires (in practice the only alrternative local loop) along with high voltage power lines there would be excessive interference and the risk of shorting out.

As I understand it most of the ESB infrastructure is fibre optic and microwave.

dam taught i had a good idea there a well back to the drawing board

So it seems that you could do it up to 5km (depending on cost), but you would need it in a separate conduit / duct.

which adds to the cost of setting it up

In fairness the fibre optic solution loos good as its capacity can be upgraded as time goes on (As I understand it).
If there was one 'breakout box' in each major area of focus it could be workable to link them up using shielded CAT5e.

{aside} btw, what's cat6 rated for? {/aside}
