Abstract: In response to a first channel associated with a first OLT and a second channel associated with a second OLT being enabled for target traffic, a traffic scheduler for scheduling the target traffic is determined by the first OLT. The first channel and the second channel correspond to a first wavelength and a second wavelength, respectively. The first OLT transmits channel configurations and offset information to an ONU, based on scheduling of a first group of data units and a second group of data units of the target traffic by the traffic scheduler on the first channel and the second channel, respectively. The channel configurations indicate channel identifications associated with the first channel and the second channel, and the offset information indicates timing information of the first group of data units and the second group of data units corresponding to physical frames transmitted on the first and second channels.

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.

Abstract: A method for channel management in an optical network unit includes receiving a disable channel action message sent by an optical line terminal, wherein the disable channel action message is used to instruct disabling a first channel of the optical network unit; transferring the state machine of the optical network unit on the first channel from the association substate of the operation state to the pending substate according to the disable channel action message; and turning off the transmitter and/or the receiver on the first channel after a specified time is reached, transferring the state machine from the pending substate of the operation state to the disabling channel status, and starting a timer.
