Abstract: The method includes receiving, at a first optical communication device, feedback information on training of a neural network from at least one second optical communication device, the neural network configured to process a signal received from the first optical communication device, the feedback information at least including a training performance indication for training of the neural network conducted at the at least one second optical communication device; updating, based on the feedback information, a first initial parameter value set for the neural network maintained at the first optical communication device, to obtain a second initial parameter value set for the neural network; and transmitting the second initial parameter value set to at least one further second optical communication device, for training of the neural network to be conducted at the at least one further second optical communication device based on the second initial parameter value set.

Abstract: A network element includes at least one processor and at least one memory. The at least one non-transitory memory including computer program code configured to, when executed by the at least one processor, cause the apparatus to determine whether a bit error rate (BER) of a FEC codeword is at or below a correctable BER, wherein the FEC codeword is transmitted between an OLT and ONU, a first percentage of the FEC codeword is at a lower order modulation, and a second percentage of the FEC codeword is at a higher order modulation, establish, based on a determination that the BER is at or below the correctable BER, a connection between the OLT and the ONU at the higher order modulation, and maintain, based on a determination that the BER is greater than the correctable BER, the connection between the OLT and the ONU at the lower order modulation.
