Just for clarity here, both switches were never moved. And since I installed a new switch and fiber module the connections were reseated on both units. Now where the switch sits in the NOC it could have gotten "nudged" as the NOC boys were in and around the other day looking for unused network ports on the walls in my area so they were most likely rummaging around the switch rack and could have done something none of them want to own up to but first I have to prove there is light at the end of that cable.
As for old equipment. The switch that was "dead" (which I believe is still good) was purchased at least 6 to 7 years ago. I replaced it with a refurbished unit but I trust my supplier. As for dust I never gave that a thought so I will try that route tomorrow when I do the paper test. Thanks again for the insight. John J.

So some of the other people have gone over some of the reasons why fiber is superior in theory. However, it sounds like you are using old gear, like I did when I was using fiber, and personally, I found fiber, for short runs with old equipment to be significantly less reliable than copper. The reason, for me, was twofold. 1. I was using old hardware that was poorly maintained by the previous owner, so there was dust, I believe, on the mating surface. There's only so much compressed air can do. 2. multi-mode fiber pulls out when jostled /much/ more readily than cat5/6, and this was in a rack where the clearance between the back of the rack and the chain-link was less than the girth of my largest sysadmin. Now, for the reasons other people on the list have stated, I do prefer fiber for long runs, or through electrically uncertain areas, but my personal experience? copper usually wins in terms of reliability, for the two above reasons. Of course, if you do fiber /right/ those two things aren't problems. But, in the case of me five years ago, well, I wasn't doing it right, but when I switched to copper, my problems in that department largely went away. -- Luke S.
