摘要：

To compare the increasing number of optical frequency standards, highly stable optical signals have to be transferred over continental distances. We demonstrate optical-frequency transfer over a 1840-km underground optical fiber link using a single-span stabilization. The low inherent noise introduced by the fiber allows us to reach short term instabilities expressed as the modified Allan deviation of 2 X 10(-15) for a gate time tau of 1 s reaching 4 X 10(-19) in just 100 s. We find no systematic offset between the sent and transferred frequencies within the statistical uncertainty of about 3 X 10(-19). The spectral noise distribution of our fiber link at low Fourier frequencies leads to a tau(-2) slope in the modified Allan deviation, which is also derived theoretically.
