Module: CDATA-GPON-MIB
OID (symbolic): CDATA-GPON-MIB::gponOltPortDdmVoltage
OID (numeric): 1.3.6.1.4.1.34592.1.5.1.1.2.17.2.1.2
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: Description.
What is gponOltPortDdmVoltage?
This read-only OCTET STRING reports the SFP transceiver's supply voltage via DDM, a health indicator that can flag a failing optical module before it causes a full outage. Admins watch for drift outside the expected supply range as an early warning sign. For example, a gponOltPortDdmVoltage reading drifting outside the expected roughly 3.3V range flags a transceiver nearing end-of-life, prompting a proactive swap before it fails completely.
