摘要
为提高BPL长波授时系统时频基准信号传输的稳定性和抗干扰能力,采用了光纤链路替代了中同轴电缆传递时频信号。介绍了该光纤链路的组成和工作原理,提供了该系统传递时频信号的稳定性实测结果。与中同轴电缆传输结果比较光纤传输有明显的优势。
With the purpose of improving the stability and anti-interference ability of time-frequency signal transmission for BPL long wave time service system, the optical-fiber link is adopted instead of the coaxial cable to transfer time-frequency signals. In this paper, the composition and principle of the optical fiber link are introduced and the measurements of the stability of time-frequency signal transmission for this system are presented. The time-frequency signal transmission via optical fiber has obvious advantages compared with that via coaxial cable.
