    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.
