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.
