Abstract:	In this paper, we present a preliminary experiment on two-way time transfer through a 25-km optical fiber link. The fiber link based on a common-path configuration can provide good reciprocity in both directions. Therefore, the propagation path delays in the fiber can be cancelled out almost entirely by employing the two-way method. The resulting data exhibit the time deviation of less than 7 ps for the averaging times from one second to one day. The frequency stability of 1×10-16 at one day has been demonstrated.
