摘要 密集波分复用(DWDM)技术在长途通信中已经得到了广泛的应用,但其高昂的系统成本极大地限制了它在城域网中的应用。粗波分复用(CWDM)技术具有较好的性能价格比,为城域网应用提供了一种低成本、高容量的解决方案。通过对城域网特点的分析,探讨了粗波分复用技术的优势及其在城域网建设方面的应用方案及网络拓扑结构,并指出了粗波分复用技术有待进一步解决的问题。 DWDM technology has been widely used in long-distance communications, but its high system cost has greatly limited its application into metro area networks (MAN). Boasting of its excellent functions and low price, the CWDM technology provides a convenient application plan into MAN that is characterized by its lost cost and high capacity. The characteristics of MAN are analyzed, and the merits of CWDM technology, its application into MAN and its network topological structure are discussed hereafter. Besides, the problems to be solved in CWDM technology are also pointed out.
