hwOpticsTxBiasCurrent
Module: HUAWEI-ETHERNET-OPTICMODULE-MIB
OID (symbolic): HUAWEI-ETHERNET-OPTICMODULE-MIB::hwOpticsTxBiasCurrent
OID (numeric): 1.3.6.1.4.1.2011.5.14.6.4.1.3
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Transmitted bias current. Unit: 0.000001A
What is hwOpticsTxBiasCurrent?
Reports the optical module's real-time laser transmit bias current, in units of 0.000001A. A bias current that drifts upward over time is a classic early-warning sign of laser aging/degradation, so admins trend this value to anticipate optic replacement.
