gponOltPortDdmTxPower
Module: CDATA-GPON-MIB
OID (symbolic): CDATA-GPON-MIB::gponOltPortDdmTxPower
OID (numeric): 1.3.6.1.4.1.34592.1.5.1.1.2.17.2.1.4
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: Description.
What is gponOltPortDdmTxPower?
This read-only OCTET STRING reports the actual optical transmit power the PON port's laser is putting onto the fiber, via DDM. Admins compare it against a port's expected rated output to catch a degrading transmitter before it causes widespread signal problems. For example, a gponOltPortDdmTxPower reading well below its rated value on one port, while sibling ports on the same OLT read normal, points to a degraded transmitter on that specific card rather than a fiber plant problem.
