摘　　要：传输光纤受环境温度变化和振动的影响,会造成射频光频率信号相位漂移,导致时频传输精度下降。为了降低光纤相位漂移对传输系统的影响,采用基于光纤干涉仪条纹计数法的光纤稳相传输技术,进行了光纤相位漂移检测和相位补偿实验验证。实验结果表明:168 m传输光纤28 h自然相位漂移了32.3 ps,采用压电陶瓷和温控光纤协同相位补偿,相位漂移量降低到1.29 fs。The transmission fiber is affected by the change of ambient temperature and vibration,which will cause the phase drift of radio on fiber frequency signal,and lead to the decrease of time-frequency transmission accuracy.In order to reduce the influence of phase drift on transmission system,the optical fiber phase drift detection and phase compensation experiment verification are caried out by using the optical fiber phase-stabilized transmission technology based on fringes counting method of optical fiber interferometer.The experimental results show that the natural phase drift of 168 m transmission fiber for 28 h is 32.3 ps,and the phase drift is reduced to 1.29 fs by using piezoelectric ceramics and temperature-controlled optical fiber to compensate the natural phase.
