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.

Abstract: One embodiment provides a media access control (MAC) module facilitating operations of an Ethernet passive optical network (EPON). The MAC module includes a frame formatter configured to generate a MAC control frame. The generated MAC control frame includes at least one of: an organizationally unique identifier (OUI) field, an QUI-specific operation code (opcode) field, and a number of fields associated with the QUI-specific opcode. Transmission of the MAC control frame facilitates realization of an EPON function based on the fields associated with the QUI-specific opcode.
