Provided is a wavelength configuration method for a multi-wavelength passive optical network (PON), comprising: an ONU scans downlink reception wavelengths and receives, during the downlink reception wavelength scan process, the downlink reception information of each downlink wavelength channel separately broadcasted by an OLT on the downlink wavelength channels of the multi-wavelength PON system; the ONU establishes a downlink reception wavelength mapping table according to the downlink wavelength information, the entries of the downlink reception wavelength table including downlink reception wavelength information, downlink optical receiver drive current information, and ONU reception optical physical parameter information; the ONU selects a downlink wavelength from the downlink wavelength information broadcasted by the OLT, and configures, according to the downlink optical receiver drive current information recorded in the related entries of the downlink reception wavelength mapping table, the working wavelength of the downlink optical receiver to be the selected downlink wavelength. Also provided are a multi-wavelength passive optical network system, and a wavelength configuration device thereof. |
