Abstract

The utility model discloses a protection switching device with a plurality of gigabit light outlets integrated in one board, comprising an interface board, a processing board, a standby processing board, and a switching board. The switching board comprises a parallel optical transmission module and a parallel optical receiving module; the interface board and the processing board are connected with the parallel optical transmission module and the parallel optical receiving module separately by parallel optical fibers. The utility model has the advantages that implementing the user side data access and the interconnection between boards by the parallel optical fiber belt, and the 1:N protection with a plurality of gigabit light outlets integrated in one board with simple method and high quality of the data transmission.

Description

technical field [0001] The invention relates to the technical field of optical network communication, in particular to a device for realizing protection switching for a single board with multiple gigabit optical ports. Background technique [0002] Common optical network equipment mainly consists of sub-boards (processing boards) that realize various functions, interface boards that realize signal input and output, and motherboards (backplanes) that complete the connection between sub-boards and interface boards. composition. The high-speed signals between the motherboard, the daughter board and the interface board are connected through differential lines. At the same time, in order to improve the reliability of the equipment, some important boards are usually backed up or 1:N protected. That is, N same boards in the device are used as the main board, and one board is used as the backup board. When one of the N boards fails, all services on the board are switched to the ba...
