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: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of ONU activation for OLT Equalizer training. The method includes determining, at OLT, configuration information indicating a bandwidth allocation dedicated for an ONU and a first target preamble sequence associated with the bandwidth allocation, the first target preamble sequence to be used by the ONU for a transmission from the ONU to the OLT on a first wavelength; transmitting the configuration information to the ONU; and receiving the transmission from the ONU from the ONU on the first wavelength, the transmission is performed by the ONU based on the first target preamble sequence.
