Abstract: The disclosure provides a method and apparatus for adjusting wavelength for an Optical Line Terminal/Optical Network Unit (OLT/ONU). The method for adjusting wavelength for an OLT includes that: a source OLT sends an adjustment notification message to a target OLT, wherein the adjustment notification message is used for indicating that an ONU is to be adjusted into a Time-Wavelength Division Multiplexing Channel (TWDM CH) of the target OLT; and the source OLT receives an adjustment acknowledgement message provided by the target OLT, wherein the adjustment acknowledgement message is used for indicating that an adjustment process of the ONU has been completed. By means of the technical solution provided in the disclosure, an ONU of a source OLT can still work normally after being switched to a channel of a target OLT, thereby achieving the effect that the continuity of a service between the OLT and the ONU may be maintained.

The method for channel switching includes that: an ONU acquires channel information of a first TWDM channel, wherein the channel information of the first TWDM channel is used for indicating an uplink wavelength and/or downlink wavelength of the first TWDM channel; and the ONU tunes the uplink wavelength and/or downlink wavelength of the ONU into the uplink wavelength and/or downlink wavelength of the first TWDM channel according to the channel information of the first TWDM channel. By means of the present disclosure, the problem of high cost caused by specially building a standby channel for each TWDM channel in a system for TWDM Passive Optical Network (PON) to provide service protection is solved, and the cost of deploying the TWDM PON system is reduced.

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.
