Abstract

The invention discloses a protection switching device for a single board with multiple gigabit optical ports, including an interface board, a processing board, a spare processing board and a switching board, and the switching board includes a parallel optical sending module and a parallel optical receiving module modules, the interface board and the processing board are respectively connected to the parallel optical sending module and the parallel optical receiving module through parallel optical fibers. The invention utilizes parallel optical fiber ribbons to realize user-side data access and inter-board interconnection, thereby realizing 1:N protection of a single board with multiple gigabit optical ports, and has the characteristics of simple design method and high quality of transmitted data.

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 single 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...
