摘要:

提出了一种准确、快速的光纤传输时延测量方法。作为一项关键技术,采用了一种基于鉴相测频的简单解模糊过程,克服了测量精度与系统复杂度之间的矛盾。优化后的系统实现了0.3 ps的高精度与0.1 ps的分辨率,和一个大的动态范围高达50公里,以及没有死区。

英文摘要:

An accurate and fast fiber transfer delay measurement method is demonstrated. As a key technique, a simple ambiguity resolving process based on phase discrimination and frequency measurement is used to overcome the contradiction between measurement accuracy and system complexity. The optimized system achieves a high accuracy of 0.3 ps with a 0.1 ps resolution, and a large dynamic range up to 50 km as well as no dead zone.
