| 中文摘要 | 在清华大学与中国计量科学研究院之间往返80 km的商用光纤链路上进行了时间频率同时传输与同步实验。采用时间频率同时传输与同步的方法,获得了7×10-15/s,5×10-19/d的频率传输稳定度结果;通过在发射端主动探测并补偿时间脉冲信号在光纤中传输的时间延迟,实现了±50 ps的时间同步稳定度指标。鉴于目前基于光纤链路的频率传输方案均受限于点对点传输的问题,设计并完成了可多点下载的频率接收系统,使时间频率传输与同步网络的建设成为可能。; The continuous, precise time and frequency synchronization system was built on an 80 km single urban fiber link,between Tsinghua University and the National Institute of Metrology. Through precise time and frequency synchronization, the frequency dissemination stability of 7�0-15/s and 5�0-19/d was obtained; with active transfer delaycompensation at the transmitting site, the time synchronization inaccuracy was< 50 ps. For the current fiber based frequency dissemination schemes, the disseminated frequencysignal can only be recovered at specific location. A multiple-access RF dissemination scheme was proposed and demonstrated. Using this method, the stable disseminatedfrequency signal can be recovered at an arbitrary node along theentire fiber pathway, which provides a solution for the time-frequency synchronization network in the future. |
