2 quick things come to mind- single mode vs multimode, or the signal is too hot and you need attenuators. -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu] Sent: Tuesday, August 24, 2004 12:48 PM To: nanog@nanog.org Subject: Weird GigE Media Converter Behavior Hello all, wondering if anyone has seen or experienced this same problem. Currently deploying an OC12 on a campus network and am using Netgear media converters. Set up the lines and had lit fiber to the building I needed it to go to. On one end (main drop) I had light and tested the connectivity which worked fine, on the other side, when I jacked up my Netgear, it flickered. Now, when I went to swap out the fiber, I noticed a full contact between the wires and the converter dropped it out. Meaning if I had the wires not fully plugged it lit, if I plugged them entirely in, it dropped. So... I ran to the other building and tried to replicate it there, and it did the same. I figured bad media converter so I swapped it out, next one worked fine. However, I took the media converter and swapped the funky acting one to yet another building and it worked fine. Anyone care to offer a thought on this? Relevant to my media converter? Bad line, "Murphy's Law", etc? =+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ J.
