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.

Predicting optical transceiver failure

A device comprises an interface, a transmitter, a receiver, a processor, and a dynamically updating indicator on the device. The interface is configured to connect to an optical network transceiver. The transmitter is configured to send to the optical network transceiver a binary signal generated by the device. The receiver is configured to receive data provided by the optical network transceiver in response to sending the generated binary signal. The processor is configured to analyze the received data and the dynamically updating indicator is configured to indicate a test status of the optical network transceiver.

The amount of current provided to a laser diode of an optical network transceiver device, the power output of the optical network transceiver device, and the device temperature of the optical network transceiver device is monitored. Based at least in part on a detected fluctuation in at least one of the amount of current provided to the laser diode, the power output of the optical network transceiver device, and the device temperature of the optical network transceiver device, a determined expected life of the optical network transceiver device is dynamically adjusted.
