A timing distribution system with femto-second stability has been developed for the RF synchronization of accelerator and the laser synchronization of the pump-probe experiments. The system uses a phase stabilized optical fiber(PSOF) and an active fiber length stabilization. The PSOF has 5ps/km/degeeC of the temperature coefficient. The active fiber length stabilization uses the phase detection of the round-trip sinusoidal wave and the deviation is compensated with the fiber stretcher. The time delay stability reached to 20fs in the case of a 900m long PSOF.

为实现加速器的射频同步和泵浦-探测实验的激光同步，研制了一套具有飞秒稳定度的时间分配系统。该系统使用相位稳定光纤（PSOF）和有源光纤长度稳定。PSOF的温度系数为5 ps/km/degeeC。主动式光纤长度稳定是利用往返正弦波的相位检测，并利用光纤展宽器进行补偿。在900 m长的PSOF中，时延稳定度达到20 fs。
