What is gponOnuOpticalTxPower?
This reports the ONU's upstream laser transmit power in dBm, read via the transceiver's DDM. A steadily dropping Tx power over weeks or months is the classic early warning sign of a laser diode aging out, well before the subscriber notices any slowdown. For example, a reading sliding from -3dBm down to -8dBm over several months signals a laser worth scheduling for replacement before it fails outright and the customer loses service entirely.
