摘要： An electrical layer subnetwork connection protection includes determining, by a network device including a processor, signal status information based on a power of an obtained optical signal. The signal status information is used to indicate a state of a subnetwork connection carrying the optical signal. The method also includes filtering, by the network device, the signal status information based on a preset first threshold. The first threshold indicates a minimum duration in which the optical signal is in a valid state. The method further includes determining, by the network device based on the filtered signal status information, whether to switch a currently used first clock to a second clock different from the clock. The first clock or the second clock is used to initialize connection monitoring information in response to the determination of whether to switch the currently used first clock to the second clock.

摘要： Embodiments of the present invention provide a method and a device for sending data in a passive optical network. A central office processing device records a downstream superframe number of a downstream data frame. A loop delay between the central office processing device and a terminal processing device is obtained according to the recorded downstream superframe number in combination with an upstream superframe number and an upstream frame synchronization sign in an upstream channel-associated data frame sent by the terminal processing device, so that the central office processing device may, after subtracting the loop delay, accurately determine, by using cached bandwidth map information and an obtained equalization delay of the terminal processing device, a start time point and an end time point for sending an upstream service data frame to an optical line terminal.
