Abstract: A method is implemented by an ONU in a 50G-PON. The method comprises receiving an encoded DS PHY frame from an OLT, the encoded DS PHY frame comprises an FEC codeword, the FEC codeword comprises an SFC field and a payload, and the SFC field and the payload are encoded with a same FEC; decoding the FEC codeword using the FEC to obtain a decoded SFC field and the payload; performing a first verification of the decoded SFC field while in a sync state of a synchronization state machine; and staying in the sync state when the first verification is successful or exiting the sync state when the first verification is unsuccessful.

Abstract: A communication method and device are provided for communication in a point-to-multi-point communication network. A communication method includes receiving, by a node of a plurality of multi-point nodes, a transmission frame comprising a header including a repetition information and a data section comprising multiple modulation symbols, with at least two repeated modulation symbols that are repeated to represent a first modulation symbol; extracting, by the node, the repetition information of the header; recovering, by node, the amplitude of each modulation symbol of the at least two repeated modulation symbols; and combining, by the node, the amplitudes of the at least two repeated modulation symbols, based on the repetition information, to reconstruct the first modulation symbol represented by the at least two repeated modulation symbols.

Abstract: A method implemented by an optical network unit (ONU) in a passive optical network (PON). The method includes receiving an encoded downstream (DS) signal from an optical line terminal (OLT), searching for a physical synchronization sequence (PSync) pattern in all possible alignments for all possible OLT bit-interleaving modes within the downstream signal, and transitioning to a pre-synchronization state once the PSync pattern has been found.

Abstract: An Optical Line Terminal (OLT) includes a downstream transceiver coupled to a Passive Optical Network (PON). The downstream transceiver is configured to communicate over a plurality of bonded channels. The OLT also includes an upstream transceiver configured to receive a downstream Service Data Unit (SDU) including user data. A processor is coupled to the upstream transceiver. The processor is configured to split the downstream SDU into a plurality of downstream blocks. The processor distributes the plurality of downstream blocks amongst selected bonded channels based on bonded channel availability for transmission over the PON via the downstream transceiver.
