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.
