Does anyone know of any ethernet extender type devices to establish a gigabit link over 2 pairs of copper? Have a short (100') inter-building link but can't run fiber or copper for that matter (historic buildings, concrete all around, squat for conduit). Have to use limited existing Cat 5 copper. Only 2 pairs available which are running at 100'TX now :( No cost effective wireless out there, is there?

It will be expensive, and worse it will be vulnerable to lightning. Any nearby strike will raise one buildings ground-stake above the others, so the ethernet will be a new ground path. When that exceeds the xfo isolation around 500V, electronics will fry unless separate protection has been provided.

Thanks... I did just dig up the BlackBox network book, but nothing good. Yeah on the voltage potential, that always bugs me. I've used various
10/100 extenders a few times with success. They're supposed to be optoisolated, but who knows! :) The best solution was to move to fiber of course... sounds like that will probably be the only solution here. Get the tractor. Unless they want some aerial line.Thx J
