摘要
40Gbit/s波分复用(WDM)系统是未来技术发展的方向 ,也是目前技术研究的热点。本文将首先分析40Gbit/sWDM系统所面临的关键技术问题 ,然后介绍美国PhotonEx公司已经商用化的40Gbit/sWDM系统及其主要技术特点 ,最后提出40Gbit/sWDM在我国的应用前景 。
40 Gbit/s WDMsystem has been the target of technology development for the future,and has drawn more attention from researchers at present.In this paper,its key technologies are presented and analyzed,and then a commercial40Gbit/s WDMsystem,offered by PhotonEx corˉporation in USA,is introduced,including its solution and main technical features.Finally we will analyze the emerging40Gbit/s WDMsystemand its applications in China,including:introduction of40Gbit/s WDMinto the real operational networks,application fields,and realization proceˉdures for its deployment.
