We have developed a laser distributor for highly accurate optical frequency transfer of optical lattice clocks. Each output has a phase stabilizer based on a Michelson interferometer with all‐fiber architecture. Varying the optical path length in the residual uncontrolled optical path to introduce phase noises between output branches, we found the residual frequency transfer instability to be much smaller than the frequency instability of current optical lattice clocks. All fiber configuration provides robustness, which allows optical lattice clocks to be used in wide range of applications not only in a laboratory, but also outside laboratory, for example, geodetic applications.
