gponOltPortDdmRxPower
Module: CDATA-GPON-MIB
OID (symbolic): CDATA-GPON-MIB::gponOltPortDdmRxPower
OID (numeric): 1.3.6.1.4.1.34592.1.5.1.1.2.17.2.1.5
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: Description.
What is gponOltPortDdmRxPower?
This read-only OCTET STRING reports the aggregate optical receive power the OLT is seeing from all combined upstream ONU bursts on that PON port, via DDM. Admins use an unusually low aggregate reading to suspect a shared-plant fault affecting many ONUs at once, rather than a single subscriber's issue. For example, an unusually low aggregate gponOltPortDdmRxPower reading can indicate a bad splitter or fiber cut affecting many ONUs on that PON leg simultaneously, versus a per-ONU optical alarm that would point at just one subscriber.
