    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.

    Abstract: A method of registering or de-registering, by an optical line terminal (OLT), one or more optical network units (ONUs) in an optical communications network. The method may include: setting one or more sub-channels for registration or de-registration among two or more sub-channels, and a size of a contention window in the one or more sub-channels; transmitting, to one or more ONUs, a registration information message including information of the one or more set sub-channels and the size of the contention window; receiving, through one of the set sub-channels, a registration or de-registration request message from the one or more ONUs, which receive the registration information message; and registering and de-registering the one or more ONUs.

    Abstract: A method of tuning a wavelength in a TWDM-PON which has a plurality of operable channels is provided. First, a second channel is added as an operating channel of the TWDM-PON in which at least a first channel is working, and then an OLT that is providing a service to an ONU through the first channel requests the ONU to tune to the second channel. In response to receiving the request, the ONU determines whether a downstream wavelength of the second channel has been recorded thereon. According to the determination result, the ONU sends to the OLT an ACK message that indicates that the ONU is able to perform wavelength tuning and then commences wavelength tuning to the second channel, or the ONU sends to the OLT a NACK message that indicates that the ONU is unable to perform wavelength tuning.
