Abstract: A device for pre-emption in passive optical networks may include a first media access control (MAC) module configured to receive a first type of data traffic and transmit the first type of data traffic to a MAC merge module. The device may further include a second media access control (MAC) module configured to receive a second type of data traffic and transmit the second type of data traffic to the MAC merge module. The device may further include the MAC merge module configured to receive the first and second types of data traffic from the first and second MAC modules, respectively, and provide the first and second types of data traffic for transmission over a port. The MAC merge module may be configured to pre-empt the transmission of the first type of data traffic over the port in favor of the second type of data traffic.

Abstract: A device for shared protection in an optical network may include a processor circuit. The processor circuit may be configured to transmit optical signals over an optical network port to a first set of optical network units (ONUs), receive an indication that an optical line terminal (OLT) is unavailable to service a second set of ONUs, transition to a protection operation mode from a normal operation mode in response to indication, and transmit optical signals over the optical network port to the first and second set of ONUs. The optical signals may include resource allocation information for at least some of the first and second set of ONUs. The device may operate as a working OLT for the first set of ONUs when in the normal operation mode. The device may operate as the working OLT for the first and second set of ONUs when in the protection operation mode.

Abstract: Embodiments provide systems and methods for a probabilistic reporting mode, where an Optical Network Unit (ONU) sends a REPORT message only when it has data to transmit. The absence of a REPORT message from an ONU is treated by the Optical Line Terminal (OLT) as indicating absence of data to transmit at the ONU. In another aspect, embodiments include systems and methods for an unsolicited burst mode, where an ONU can be configured to transmit data in the upstream in an unsolicited manner. The unsolicited burst mode includes mechanisms to ensure that no data is lost due to potential collisions between ONUs.

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.
