Feasibility analysis and design of multi-mode optical switching

The combination of satellite optical switch and transmission can realize the direct switch of satellite optical data, and avoid the problem that it is difficult to realize the super large data capacity switch under the condition of limited processing ability of satellite electric devices. In this paper, the characteristics and application requirements of satellite network are analyzed deeply. By combing with the constraints of space environment, device selection, and engineering implementation, a multi-mode optical switching technology scheme of satellite network based on the optical burst switching system is proposed. The scheme can support the three modes of optical circuit switching, optical flow switching and optical burst switching at the same time. It is often suitable for satellite networks with limited resources of satellite to ground and inter satellite links. It needs to support the application environment of multiple service systems optical link multiplexing.
