摘　　要：数字光纤直放站的良好特性和在公网GSM系统上的大规模应用,使其在铁路GSM-R系统上也开始得到应用。数字光纤直放站与模拟光纤直放站有诸多不同的特性,其在铁路上的应用对动态检测提出了新的要求。在动态检测过程中,深入探讨采用数字光纤直放站环形组网模式延伸基站覆盖方式可能影响铁路GSM-R服务质量的几个方向,为今后采用数字光纤直放站延伸GSM-R基站覆盖的铁路进行动态检测提供新思路。The good characteristics of the digital optical fiber repeater and its large-scale application in the public network GSM system have made it gradually applied in the railway GSM-R system.Because of the many differences between the digital optical fiber repeater and the analog optical fiber repeater Therefore,the application of digital optical fiber repeaters on railways puts forward new requirements for dynamic inspection.In this paper,the use of digital fiber repeater ring network mode to extend the coverage of base stations,and several directions that may affect the quality of railway GSM-R service,have made an in-depth discussion in the dynamic inspection process.It provides a new idea for the use of digital optical fiber repeater to extend the railway covered by GSM-R base station for dynamic inspection.
