nbsSigCondVoaPortTxAttenuAdmin
Module: NBS-SIGCOND-MIB
OID (symbolic): NBS-SIGCOND-MIB::nbsSigCondVoaPortTxAttenuAdmin
OID (numeric): 1.3.6.1.4.1.629.227.1.2.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Persistent and immediately updated. User-requested attenuation to be applied before transmitting signal, expressed in millidecibels (mdB). Not supported value: -200000
What is nbsSigCondVoaPortTxAttenuAdmin?
This read-write value is the operator-requested attenuation, in millidecibels, to apply to the signal before it is transmitted out this optical port. Network engineers use it to trim launch power on a fiber run that's too strong for the receiving equipment or amplifier at the far end, and the request is applied and saved immediately. Writing 1500 mdB (1.5 dB) knocks the transmit power down by that amount; -200000 marks ports where transmit attenuation isn't supported.
