Description: Low Alarm TX bias current in micro-Amps yielding a total range of 0 to 131 mA.

What is acdSfpThreshLbcLowAlm?

This OID specifies the low alarm threshold for TX bias current, catching when the laser's drive current falls too low (0–131 mA range). A weak laser bias causes poor optical output and link performance; this threshold alerts the team to a failing transmitter before the signal becomes unusable. A value of 20000 micro-amps (20 mA) triggers an alarm if the bias current drops below the module's minimum operating threshold.
