optMuxPhysInstValueBackreflectionTx
Module: ADVA-FSPR7-PM-MIB
OID (symbolic): ADVA-FSPR7-PM-MIB::optMuxPhysInstValueBackreflectionTx
OID (numeric): 1.3.6.1.4.1.2544.1.11.11.17.2.1.1.1.31
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Physical Port Backreflection power, measured at Tx Port.
What is optMuxPhysInstValueBackreflectionTx?
This OID reports the backreflected power detected at the transmit port in dBm, indicating reflections from the transmission fiber. Anomalously high backreflecion signals connector problems, connector contamination, or fiber cracks that degrade the link. A typical value is -45.2 dBm.
