    Abstract: An OLT comprises a processor configured to: obtain optical powers associated with ONUs, and generate an instruction instructing a transmit order of transmissions based on the optical powers; a transmitter coupled to the processor and configured to transmit the instruction to the ONUs; and a receiver coupled to the processor and configured to receive the transmissions from the ONUs based on the instruction. An apparatus comprises a receiver configured to receive an instruction instructing a transmit order of transmissions based on optical powers associated with ONUs; a processor coupled to the receiver and configured to process the instruction; and a transmitter coupled to the processor and configured to transmit a transmission based on the instruction.

    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 first apparatus in an optical communications network, the first apparatus comprises a transmitter; a receiver; a first MAC; and a first oDSP coupled to the transmitter, the receiver, and the first MAC and configured to communicate a message via a dedicated C&M channel with at least one of the first MAC, a second MAC in a second apparatus in the optical communications network, or a second oDSP in the second apparatus. A method comprises receiving an FS message comprising a PLOAM field, the PLOAM field contains oDSP-related C&M information, and the oDSP-related C&M information comprises a message type ID field and a Message_Content field; reading the message type ID field; and deciding, based on the message type ID field, whether to read the Message_Content field.
