Maybe I misunderstand the DOM parameter, but would attenuation have an influence on what the TX power is according to the transceiver itself? To me it sounds like a faulty transceiver, though an optical power meter could qualify that a bit. Not really related but we have previously had a few transceivers logging "Voltage low alarm; Operating value: 0.00V". We ignore these since they work fine and since 0.00V sounds more like a measuring bug than actual low voltage. -- Peter _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
