摘要

In order to make the fiber-based frequency synchronization system suitable for the use of large-scale scientific and engineering projects in which the ambient temperature of the fiber links change dramatically,we design a non-harmonic frequency dissemination system immune to strong temperature fluctuation.After the lab tests,in which the ambient temperature of the fiber fluctuates 40℃/day and 20℃/h,respectively,the relative frequency stabilities of this system reaches 4.0 × 10-14/s and 3.0 × 10-16/104 S.It is demonstrated that the proposed non-harmonic scheme shows a strong robustness to complicated working environment with strong temperature fluctuation.
