摘要
An optical communication system includes a plurality of Customer Premises Equipment (CPE) each having a reverse power supply and configured to transmit and receive data and provide power over a wire pair connected thereto. An optical network unit is formed as a plurality of communication ports. A respective communication port is configured to provide communications data service with a respective CPE by transmitting and receiving data therewith. A power management circuit is connected to the communication ports and configured to receive power provided by each reverse power supply at a respective CPE and manage power consumption in the ONU. A processor is configured to receive alarms generated by at least one of a CPE and ONU indicative of a power fault condition and process the alarms and discriminate between different power fault conditions.
