Description: This contains the internally measured SFP TX laser bias current. Units are in microAmps, and range from 0 to 131000uA (131mA). Located at I2C address 0xa2, Bytes 100 & 101 (MSB, LSB)
What is sfpTxBias?
Reports the SFP's internally measured transmit laser bias current in microamps, up to 131000uA (131mA); an admin watches this for a drifting or degrading laser, since bias current typically rises as a laser diode ages toward failure.
