The communication transmission system occupies the most important position in urban rail transit. It is the platform for carrying information in various communication subsystems and related business systems. Taking Shanghai Metro Line 13,which is open to traffic, as an example, this paper analyzes the characteristics and advantages of MSTP transmission technology by comparing the various types of transmission systems in current urban rail transit. From the selection of communication transmission equipment, system networking and network Protection and other aspects, the implementation of SDH-based MSTP transmission technology in urban rail transit applications.
