摘要：

<正>Two 87Sr optical lattice clocks（OLCs） are being developed and operated at the National Institute of Metrology（NIM）, located on different campuses that are 40 km apart. In order to compare the optical frequencies of these two Sr OLCs, a 58-km noise canceled fiber link is built to transfer both a 1542-nm transfer laser and a microwave reference from Changping campus to Hepingli campus.
