Abstract: The present disclosure discloses a method and an apparatus for implementing registration. The method includes: tuning, by optical network units (ONUs), own reception wavelengths to a downlink wavelength corresponding to any one of time-wavelength division multiplexing (TWDM) channels; and receiving, from optical line terminals (OLTs) by the ONUs, downlink frames containing operator information, judging that the operator information in the received downlink frames is same as operator information preconfigured in the ONUs, searching for an uplink wavelength corresponding to a current received wavelength in a corresponding relationship between the uplink wavelength and the downlink wavelength received from the OLTs, and tuning own uplink wavelengths to the searched uplink wavelength for registration.
