Using fuses in CAT 5 premise wireing

By janwhite@appliedcomputers ·
We have a vendor that wants use to use fuses to protect against possibe overloads on our building to building underground shielded CAT 5 cableing. Is this normal or even within specs. Most ports on hubs and switches will just spare themselves out ifthey have a problem, barring a lightning strike. Any ideas or feedback?

Electrical contractors are being called upon more to use fuses to prevent fires in conduits and bussways from overloaded cables.
I suspect that in a few years, this will become part of the N.E.C.

My only concern would be that the fuses and fuse holders need to be capable of 100MHz or higher so as not to impact your network traffic and reliability.

For safety reason

First of all I would like to clarify two things. There are two things that is need to be present at both ends of the underground cables. A ground cable should be present (lightning arrester and rod is higly recomended.) For the fuse your contractor that want to use is not the ordinary electrical fuse. There is a big diffrence between the data fuse and a electrical fuse. Electrical fuse is used to **** off if the current (ampere) that is flowing thru it exceded the rated capacity. On the data fuse... this is not an ordinary one. It is a gas fuse and it is sensitive. Here in the USA there is building code that covers that and it is a must to have it.
I know the switch are disposable, but how about if the lightning strike went thru the computer and there is a person infront of that computer.

Another thing which is worthwhile to note is that that data fuse is different from the noise filtering device.
Believe me it is a wothwhile investment to have those fuses installed
