EPON技术在铁路区间通信系统的应用

以兰青二线内试验段区间通信系统改造工程为背景,在普通铁路区间通信系统中植入EPON技术,占用长途光缆中的光纤传输介质,即铁路长途光缆+光区话柱方式,实现铁路车站与区间语音、数据、图像综合通信业务的区间宽带接入,既符合普通铁路区间通信系统用户的使用习惯,又弥补了接入业务的不足,降低了维护成本,提升了工作效率。

Application of EPON Technology in Section Communication System

Taking the section communication system renovation project of the test line in Second Lanzhou -Qinghai Line as an example, EPON technology is implanted in the ordinary wayside communication system with long-distance optic cable as transmission medium, e.g. the combination of railway long-dis- tance optic fiber and optical column, to achieve the broadband access of an integrated communication services of voice, data, and images to railway stations. So, the user~ operation habits in ordinary wayside communication systems can be kept on while the deficiency of access services in ordinary wayside commu- nication systems can be compensated, reducing the costs of maintenance and improving the efficiency of work.
