Abstract: Techniques, apparatus and systems are described for accommodating the optical network units (ONUs) having different nominal upstream bitrates on the same passive optical network (PON) system by making the specified burst preamble and the bandwidth map allocation record format invariant with respect to the nominal upstream bitrate of a target ONU. The disclosed techniques, apparatus and systems allow seamless evolution of the lower-bitrate services to higher-bitrate services offered to an end-user without need to upgrade the central office equipment. In addition they can avoid the adverse consequences of inadvertently connecting a high-upstream-bitrate ONU to a lower-upstream-bitrate network.

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.
