光通信技术的发展趋势展望

Outlook on development trend of optical communication technology

光通信技术处于一个高速发展时期,当前电信网的主要传送体制SDH走向网络边缘,向融合的多业务平台转型;FTTH使得"最后一公里"部分的接入网络从"贵族"走向"平民";IP OVER WDM在IP业务承载方面具备不可替代的优势;由于技术上的重大突破和市场的驱动,这几年WDM发展十分迅猛;自动交换光网络(ASON)是近几年中出现的智能光网络的主流技术;未来通信将是全光网络,网络的优化、路由、保护和自愈功能在未来光通信领域越来越重要。

At present, the optical communication technology is in a fast development time and current telecommunication network＇s main transmission system SDH moves toward the network edge to fusion multi-service platform reforming.FTrH causes ＂the last kilometer＂ the part turning on network to move towards the civilian population from the nobility.IP OVER WDM has the irreplaceable superiority in the IP serviee load bearing aspect.Because of the technical important breakthrough and the market-driven, the WDM has developed rapidly. In the recent several years the Automatically Switched Optical Network （ASON） has become the intelligent light network mainstream technology.Future communication will be all optical network and the network optimization, the route, the protection and the self-recovery function are getting more and more important in the future optical communication domain.
