h3cOnuLaserOnTime
Module: A3COM-HUAWEI-EPON-MIB
OID (symbolic): A3COM-HUAWEI-EPON-MIB::h3cOnuLaserOnTime
OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.42.1.5.5.1.5
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The ONU laser on time measured in TQ units. If the object value is 0x7FFFFFFF, it means h3cOnuLaserOnTime is unknown.
What is h3cOnuLaserOnTime?
This read-only integer reports the cumulative time the ONU's transmit laser has been active, measured in TQ units (125-microsecond quantum), or 0x7FFFFFFF if unknown. It indicates laser aging and helps predict lifespan or detect failures. A high on-time might justify preventive replacement.
