Predicting optical transceiver failure

Abstract:

The amount of current provided to a laser diode of an optical network transceiver device is monitored, the amount of current reaching a threshold limit is detected, and the power output of the optical network transceiver device is monitored. Based at least in part on the detection that the amount of current has reached the threshold limit and the monitored power output of the optical network transceiver device, a likelihood of failure of the optical network transceiver device is predicted.
