Hi guys, I've been running CAT5 in businesses and homes for a while but I have an installation question (before we do something really wrong!)
We have been rolling out a fibre WAN install over a large site in several stages... One of these stages has us putting a fibre link into a remote building that has a porta-cabin next to it... As the power to the porta-cabin comes from the same building along a route we will want to run CAT5 (from the fibre switch to PC's in the porta-cabin) we have purchased some Shielded (solid-core) CAT5.
Now my question is around the shielding, as the cable will be going outside (and isn't armoured) we want to protect it in some way, it's only travelling a short distance (3-4 feet?) so I was thinking just a length of hosepipe. It would be protected from the environment and would protect the shielding from ever being 'out in the open'?
Now we enter into the grounding aspects of shielding and earth differentials!
It is my understanding that as the porta-cabin is on the same power supply as the building the earth differential is not a problem, but as we are still using shielded CAT5 do we still need to ground it in some way - as the shielding runs the risk of picking up lots of RF interference where is it being laid (right next to a big multi-phase power feed)? As none of the other equipment (patch leads, switches & PC's) will be grounded additionally (than the existing power connections) is this dangerous to leave ungrounded?
