摘要

研究了基于光纤环形网的多点高精度时频传递的方法,提出了终端站对钟差自感知的方案,将对钟差的感知测量以及补偿转移到终端站执行,实现网络中各个终端站与中心站的时频同步。搭建了长度为100 km的光纤环形网多点时频传递系统,实验研究了链路中色散带来的不对称性偏差的校消方法,验证了链路温度变化下的多点时频传递性能,测量的时频传递同步误差的峰峰值低于400 ps,均方根误差小于60 ps,表明终端站可以在光纤环形网的任意位置灵活接入。

Abstract

We study a ring fiber network based multipoint time-frequency dissemination method with high precision. Further, a novel scheme that can realize self-perception for clock difference is proposed; the sensing measurement and compensation for the clock difference are located at remote stations. Time-frequency synchronization can be achieved between the remote stations and the local station. Subsequently, we perform a time-frequency dissemination experiment via a 100-km ring fiber network to study the correction method of asymmetry deviation introduced by dispersion. The multipoint time-frequency dissemination performance is verified under link temperature variation. The measured peak-to-peak value of synchronization error of time-frequency dissemination is smaller than 400 ps, and the root mean square error is smaller than 60 ps. The results show that the remote stations can be accessed anywhere in the ring fiber network.
