This says that high power VFLs can burn them out too.

Is there a rule of thumb to guess that based on the dynamic range? I’m trying to determine if a dark fiber provider might have blasted a ZR optic with an OTDR at close range. We know they were out testing recently, and the manufacturer is saying receiver may have been overloaded and the link is way too long for the far end transceiver to have done it. I’m not out to blame anybody, this is just an educational exercise. -------------------------------------------------------------------------------- -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -------------------------------------------------------------------------------- -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
