| Abstract: | All-Optical Network(AON) can realize the transfer, switch, route and error recovery of high speed info-stream. The key to realization of photonic network is to replace electrical switch with optical one. Photonic switching technology is the essential precondition of the implement of key functions of AON, and it is also the hotspot of research and development of communication companies . This paper, introduces the development of processes and characteristics of AON, and analyzes the basic principle, performance guideline of photonic switching technology. These techniques are also compared and the future of photonic switching technology is envisioned in the paper. |
