我们演示了一种基于频率梳的时间传输技术，该技术安装在159公里长的光纤链路上。时序信息利用强度调制方案叠加到itu信道滤波锁模激光器的光脉冲序列上。利用往返相位噪声消除技术补偿环境引起的光程长度波动。当光纤链路稳定时，在5秒时的时间偏差为300fs，精度为100ps。
We demonstrate a frequency comb-based time transfer technique on a 159 km long installed fiber link. Timing information is superimposed onto the optical pulse train of an ITU-channel-filtered mode-locked laser using an intensity modulation scheme. The environmentally induced optical path length fluctuations are compensated using a round-trip phase noise cancellation technique. When the fiber link is stabilized, a time deviation of 300 fs at 5 s and an accuracy at the 100 ps level are achieved.
