Abstract: A method for activating an Optical Network Unit (ONU) is provided, where the ONU communicates with an Optical Line Terminal (OLT) through a plurality of paths. The method includes: finding the ONU by the OLT on a path of the plurality of paths; and/or selecting one path from the plurality of paths and performs a ranging on the ONU on the selected path, by the OLT. Through this solution, the OLT finds the ONU and performs ranging on each ONU on only one of the plurality of paths, that is, does not activate each ONU on all paths, thereby quickly completing an activation process of a multi-path PON in a multi-path PON structure and improving work efficiency.

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.
