Description: This contains the internally measured TX output power. Units are in uW (micro Watts), and range from 0 to 6554uW (6.535mW). This value is not valid if the transmitter is disabled. Located at I2C address 0xa2, Bytes 102 & 103 (MSB, LSB)
What is sfpTxPower?
Reports the SFP's internally measured transmit optical output power in microwatts, up to 6554uW (6.535mW), not valid while the transmitter is disabled; an admin compares this against the expected launch power for the fiber type to confirm the transceiver's laser is healthy.
