摘要
随着各种新兴宽带业务的不断涌现与发展,在城域网中引入DWDM(Dense Wavelength Division Multiplexing:密集波分复用)技术已成为大势所趋。从DWDM技术发展现状出发,讨论了其原理与关键技术。重点介绍了DWDM技术在城域网中的应用及阿尔卡特产品1696MSPAN,接着讨论使用1696MSPAN组建城域网的组网方式。
With the fact that various new broadband services spring up and develop, the introduction of DWDM （Dense wavelength division multiplexing） into Metropolitan Area Network has already become an irresistible trend. From the status quo of DWDM technology, this paper discusses in detail the technical principle and key technologies of DWDM, including its applications in Metropolitan Area Network, then stresses the introduction of Alcatel product 1696MSPAN, and describes the design mode of MAN by using it.
