Optical module bias and mod current
The two factors that affect the extinction ratio in the fiber optical module,bias current (bias) and modulation current (Mod), tentatively regarded as ER=Bias/Mod. Laser bias current degradation indicates declining optical transmitter performance, risking elevated BER and link instability. Our field telemetry shows real-world bias drift often precedes FEC alarms. Bias typically refers to how much DC current is required by the laser to keep it functioning within specs. If one of the five parameters is abnormal, ONU registration will be abnormal or packet nt are all for the PON port. Transmitted and received powers.
