    Abstract: A method of tuning a wavelength of a tunable ONU in a TWDM-PON is provided. The method includes transmitting a wavelength change request message from a source OLT to request the ONU to change a wavelength thereof from a first wavelength to a second wavelength and in response to the wavelength change request message, transmitting a wavelength change response message from the ONU to the source OLT to indicate whether or not the ONU can change a wavelength thereof. The wavelength change request message is ID information for specifying an ONU that is requested to change a wavelength thereof, and the message may comprise one of the following: system ONU ID, channel ONU ID, and individual ONU ID.

    Abstract: Provided are a power management method and apparatus of an ONU supporting a slicing function. A power management method performed by a power management apparatus of an ONU supporting a slicing function includes receiving a first message for discovering a power management attribute of an ONU including at least one slice from an optical line terminal (OLT), transmitting a second message including the power management attribute of the ONU to the OLT in response to the first message received, receiving a third message for setting up a power management parameter for each slice included in the ONU from the OLT, setting up the power management parameter for each slice included in the ONU based on the third message received, and transmitting a fourth message including a set up result of the power management parameter for each slice included in the ONU to the OLT.

    Abstract: Disclosed is a method of registering a new optical network unit (ONU) to be performed by an optical line terminal (OLT). The method includes transmitting a ranging notification message to a centralized unit (CU)/distributed unit (DU) to register the new ONU, receiving scheduling information for registering the new ONU from the CU/DU in response to the ranging notification message, transmitting a serial number request message to a service region in which ONUs are present based on the received scheduling information, and when the serial number response message is received from the new ONU in response to the serial number request message, registering the new ONU that transmits a serial number request message. The transmitting of the serial number request message is performed through a multi-quiet zone of a short period.
