Abstract: Provided are wavelength switching and configuration methods and devices for a Passive Optical Network (PON). The switching method includes the following operations. An Optical Network Unit (ONU) responds to a ranging request message sent by an Optical Line Terminal (OLT) on a first uplink wavelength supported by the ONU. The ONU receives ranging information sent by the OLT. The ONU uses the received ranging information as ranging information about a second uplink wavelength of the ONU, and performs data transmission on the second uplink wavelength according to a bandwidth allocation from the OLT. A path transmission time difference caused by a wavelength interval between the first uplink wavelength and the second uplink wavelength is less than a corresponding fault tolerance range when the OLT receives data. The ranging information is obtained by the OLT according to a ranging response sent by the ONU on the first uplink wavelength.

Abstract: Embodiments of the present application provide a method and apparatus for opening a quiet window, and a registration method, apparatus and system. The method for opening a quiet window includes that: a first quiet window is opened when it is determined that the first quiet window needs to be opened, wherein the first quiet window is used for Optical Network Unit (ONU) discovery. According to the embodiments of the present application, a first quiet window is opened only when it is determined that the first quiet window needs to be opened, rather than periodically opening the first quiet window, such that the efficiency of the first quiet window is improved and the impact of the first quiet window on a data transmission delay is reduced, thereby reducing a transmission delay of a Passive Optical Network (PON) system.
