Abstract

We demonstrate a precision frequency measurement using a phase-stabilized 120 km optical fiber link over a physical distance of 50 km . The transition frequency of the Sr 87 optical lattice clock at the University of Tokyo is measured to be 429228004229874.1 ( 2.4 ) Hz referenced to international atomic time. The results demonstrate the excellent functions of the intercity optical fiber link and the great potential of optical lattice clocks for use in the redefinition of the second.
