acdSfpThreshStatusLbcHighAlm
Module: ACD-SFP-MIB
OID (symbolic): ACD-SFP-MIB::acdSfpThreshStatusLbcHighAlm
OID (numeric): 1.3.6.1.4.1.22420.2.4.4.1.11
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-only
Description: This is to indicate if the Laser Bias Current reaches or overpasses the High alarm threshold.
What is acdSfpThreshStatusLbcHighAlm?
This OID returns true/false to indicate if the SFP laser's bias current has exceeded the high alarm threshold, signaling possible laser degradation or failure. Excessive bias current causes the laser to age rapidly and eventually fail, reducing module lifespan from years to months. A true alarm value means the laser is drawing too much current—for example, 100 mA when the alarm is 95 mA—and should be replaced soon.
