swSfpRxPower
Module: FA-EXT-MIB
OID (symbolic): FA-EXT-MIB::swSfpRxPower
OID (numeric): 1.3.6.1.4.1.1588.2.1.1.1.28.1.1.4
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: This object identifies the Rx power consumption of SFP.
What is swSfpRxPower?
This value reports the optical receive power level measured by the SFP transceiver, in dBm. Admins compare it against the transceiver's specified receive sensitivity range to diagnose weak or degraded fiber links before they fail outright. An Rx power reading of -25 dBm on a transceiver rated down to -20 dBm would indicate an unacceptably weak signal, likely from a dirty connector or excessive fiber loss.
