Using CAT5 Outside. I have no choice.. What do you think?
tuyyo2000 Jun-21-00 01:38 AM
Im trying to network 2 PC's. 1 on the forth floor and one on the first of my building., I understand that i should not lay cable from the outside of the building. Do i have an alternative? Can i use something to insulate it?

I would fish it through the walls or use wire mold on the inside of the building. I suppose you could use a metal conduit on the outside of the building if it is correctly grounded, but it still might present a lightning danger. Until you have actually seen a couple of PC's fried by lightning striking a network wire and the potential danger it presents to the users of those PC’s, it is hard, I presume, to be as serious about it as I am. You might be able to use a phoneline connection (e.g., http://duxcw.com/digest/Reviews/Network/dlink/dhn910/dhn910.htm) or wireless product (e.g., http://intel.com/network/products/wireless.htm). Move one of the PC’s, people? Larry

Installing a metal Condiut on the outside of the building? Can the CAT5 be installed in some kinda of Rubber coated tubbing or pipe. I feel anything metal will be a hazard.

I don't believe you can insulate it against lightning. I would at least look at possible ways to run it inside. Larry

I appreciate your feedback. Would i be able to insulate it with something other than a metal conduit? Some kind of Plumbing or rubber Tubing?
It may be easier to install from the side of the building. Again. I appreaciate all your comments.

As I said, I don't believe you can insulate the cable from lightning—the voltages are extremely high. If it can be done safely at all, and I doubt it, the cable should be shielded with metal conduit, which is properly grounded (a rod in the ground several feet deep). Theoretically, if lightning strikes, it should be conducted to ground through the conduit instead of to computers via the network cable. However, in my experience lightning can be quite unpredictable and I would not trust this scheme to protect computer users. I have repeatedly said enough on this subject: all that I know about it is now in the forum. Larry

if you MUST run your cable outside, then why don't you use a outdoor type cable, preferably gel-filled. you can also ground it. not only do you need to protect it from lightning, but also the weather elements.
