Abstract: In this study, a promotion of quantum frequency standard and precision measurement and other professional development are proposed in order to obtain a unified time benchmark, higher precision requirements have been put forward on the high-precision time frequency ratio. On the basis of 124KM optical fiber time transfer system platform, combined with the experimental data in the recent 2 years, analysis of various factors that affect the time comparison of optical fiber are presented and the adaptive threshold method is proposed to deal with the time difference of fiber optics in the system. In addition, simulation results show that the application of proposed method can obviously improve the accuracy of comparison which also prove the validity of the algorithm.
