Module: CDATA-GPON-MIB
OID (symbolic): CDATA-GPON-MIB::gponOltPortDdmTxBiasCurrent
OID (numeric): 1.3.6.1.4.1.34592.1.5.1.1.2.17.2.1.3
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: Description.
What is gponOltPortDdmTxBiasCurrent?
This read-only OCTET STRING reports the laser bias current of the PON port's transmitter via DDM, a classic health indicator where a rising trend over time typically signals laser aging. Admins track this trend specifically to schedule proactive optics replacement before a hard failure takes down every ONU on that port. For example, watching gponOltPortDdmTxBiasCurrent climb steadily over several months on one PON port lets an admin schedule a proactive SFP swap before the laser fails outright and drops every subscriber ONU on that port.
