    Abstract: A system and method for reducing power consumption in a Passive Optic Network (PON). The system comprises an optical line terminal (OLT), an optical network unit (ONU), a traffic-detection module configured to detect status of traffic to and from the ONU, and a power-management module configured to place the ONU in sleep mode based on the detected traffic status. The ONU includes transmitting and receiving components that are selectively powered down during the sleep mode based on a type of traffic in the ONU.

    Abstract: One embodiment of the present invention provides an optical line terminal (OLT) in an Ethernet passive optical network (EPON). The OLT includes a number of bi-directional optical transceivers. At least one bi-directional optical transceiver is coupled to an optical network unit (ONU) group that includes a number of ONUs. The OLT further includes a first downstream media access control (MAC) interface configured to provide a first downstream control signal and a splitter configured to split the first downstream control signal to a number of sub-signals. At least one sub-signal is configured to control downstream transmission of a corresponding bi-directional optical transceiver to a corresponding ONU-group.
