摘　　要：采用SDH方案的线路,在线路延伸设计时需要考虑如何将延伸段骨干网接入既有SDH传输网,并确保不对线路运营造成影响.针对一期采用SDH传输方式的情况下如何对延伸线组网,提出了5种解决方案并进行了对比,可供相关地铁线路延伸建设参考.For a line that adopts SDH as its transmission system,the backbone network of the extension section of the line should be connected to its existing SDH transmission system in the design of the extension.section of the line and it is required that there is no impact on the operation of the line.As for the line that has adopted SDH in its first phase project,five solutions to the network of its extension section are proposed and compared,offering reference for the construction of the extension of other metro lines.
