摘要
全光网一直被认作光通信网的终极目标。近年来随着液晶、微电子机械系统(micro-electro-mechanical system,MEMS)技术的发展和波长选择开关(wavelength selective switch,WSS)等可配置光器件的成熟,全光网再次成为研究和应用的焦点。在介绍全光网技术现状和系统架构的基础上,重点梳理了相关标准化研究的最新进展,进一步探讨了全光网有待解决的技术问题,最后对其未来发展前景进行了展望。
All-optical network has been considered as the ultimate goal of the optical communication network.With the development of liquid crystal and MEMS technologies and the maturity of configurable optical devices such as WSS,all-optical network has once again become the focus of research and application.Based on the technical status and system architecture of the all-optical network,the technical problems to be solved in the all-optical network were discussed,the latest developments in standardization research were sorted out,the typical problems existing in the all-optical network standardization were further analyzed,and its future developments were finally forecasted.
