当前光传送网络及技术发展策略

Current Optical Transmission Network OTN and Technological Development Strategies

首先介绍了目前国内光传输领域的一些新景象，接着介绍了光传送网络（OTN）演进中存在的困惑和问题，然后分别提出电层网络如何向光层网络平滑演进以及这期间光传输技术如何继续完善和发展的观点，最后对未来光传送网络做了一番展望。

In this paper, the new phenomena in optical transmission fields of China is introduced firstly, perplexity and problems in the evolution of OTN are followed, and then the means of electrical layer network being evaluated smoothly into optical layer network and viewpoints on the continuing improvement and development of optical transmission technology are presented． At last, it gives prospects of the future OTN．
