From irvw at linfield.edu Fri Jan 16 13:49:33 2004 From: irvw at linfield.edu (Irv Wiswall) Date: Fri Jul 16 16:34:45 2004 Subject: fiber termination Message-ID: <1291623731.1074260973@[10.219.171.53]> We do some of our own fiber termination and are wondering what other people do. We have equipment that can measure dB lost, but nothing that can measure distances that would be useful when trying to determine failure point when things don't work. This additional piece of equipment is about 4 grand so we're not anxious to run out and buy it. So I'm curious how many campuses do any of their own fiber termination, and if you do, what test equipment you use.

We use a dB lost meter as well to test the terminated fiber. We usually know something is wrong with a fiber when it's dB loss differs greatly from the other fibers in the same cable. We use that as a sign that something is wrong and we redo the termination. The only distance measuring device we have is a wheel that we use to walk the route of the fiber and it tells us the distance in feet. We add extra length for the loops and between floor and come up with a good estimate of the length. It you need more information, please contact Mike Hubbard (hubbard@whitman.edu). He does most of our fiber termination.
