摘要
城域网是连接传统长途网与接入网的桥梁,是传统电信网与新兴数据网络的交汇点及今后三网融合的基础。本文比较了目前常用的城域网技术,并分析了CWDM技术应用于城域网的优势,同时给出了目前国内的CWDM厂商和CWDM技术的应用现状。文章最后预测了CWDM技术的应用前景。
Metropolitan area network is a bridge linking traditional long-distance network with access network, an intersecting point of the traditional telecom network and the new digital network, and the foundation of the merger of the three networks. Metro technologies, which are commonly in use at present, are compared, and the advantages of CWDM technology of its application in Metro are analyzed, and at the same time the information of CWDM manufacturers and application status of CWDM technology are listed in this article. Application prospect of CWDM technology is also forecasted before conclusion of the paper.
