Studyon High Precision Disciplined Time-Frequency Transferring Experiments through Optical Fiber Link

阐述了光纤高精度时间频率伺服传递的基本原理、误差来源和系统技术方案。实验上完成了100km光纤链路温度缓变和剧变条件的授时实验,实验授时同步误差峰峰值小于400ps。实验结果表明光纤高精度时间频率伺服系统的性能可以满足商用原子钟间的高精度时间比对与传递要求。

The basic principle of high precision disciplined time-frequency transfer through optical fiber link, the analysis of error sources and the structure of the disciplined clock system are expatiated. Experiments through 100 km optical fiber are done when the temperature slowly changes and extremely changes. The result presents that the peak-to-peak value of synchronization error is smaller than 400 ps. And the performance of the system can satisfy the demand of high precision and synchronization time transfer between commercial atomic clocks.
