Abstract

As a prospective test of the countrywide high-precision time and frequency transfer optical fiber network, we recently demonstrated an optical frequency transfer link over commercial fiber networks in Shaanxi Province. A fractional frequency instability 8.4×10^-19 at 10⁴ s is achieved over the 400-km round-trip optical frequency link from NTSC, Lintong District to Tongchewan, Ningshan County. Further study on optical frequency transfer over 1000 km is carrying on. This work will contribute to the construction of the High Precision Ground-based Time Service System (GTSS) in China.
