铁路的快速发展对通信系统提出了更高的要求,大容量、抗干扰、高速率的光通信系统必将成为铁路通信系统的骨干。主要叙述除铁路光缆干线长途通信之外的光通信应用,包括列车定位追踪系统的光纤传感技术、融入铁路无线移动网络的光纤无线技术和铁路系统应用无线光纤技术的前景,并提出以标准化工作为先导,推进光纤技术在我国铁路中的应用。
The rapid development of the railway has put forward higher requirements on the communication system. The optical communication system with large capacity, anti-interference and high speed will surely become the backbone of the railway communication system. This paper mainly describes the application of optical communication besides long-distance communication of railway optical trunk lines, including optical fiber sensing technology of train positioning and tracking system, optical fiber wireless technology integrated into railway wireless mobile network and wireless optical fiber technology applied to railway system. The standardization work As the guide, promote the application of optical fiber technology in our country’s railway.
