摘　　要：　分析现有城域传输网络的特点,并说明其局限性.介绍城域粗波分复用(Metro-CWDM)和密集波分复用系统(Metro-DWDM)的最新发展状况,比较波分系统网络与现有传输网络(MSTP)的各种特性.提出在城域网建设方面,采取由现有传输网络过渡到粗波分复用网络,最后再升级到密集波分复用网络的策略.Main features of the MAN network and its disadvantage are described. The development of Metro - CWDM and Metro - DWDM are introduced. The main features of MSTP, Metro- CWDM and Metro - DWDM are discussed. For a new telecom company, the MAN network can be build up from MSTP to Metro - CWDM. Finally, constract the desired Metro - DWDM, with benefit of investage and income.
