Title: Time synchronization system and time synchronization method
Inventor: SAKUMA HIROKI
IPC: H04B10/077
Filed: 2019-02-15
Abstract: [Problem] To synchronize timings at which regularly spaced pulse signals (1PPS signals) are transmitted and received between communication devices even when the optical characteristic or optical fiber length of an optical fiber connecting the communication devices changes. [Solution] A time synchronization system 20 transmits/receives and synchronizes regularly spaced pulse signals between a local device L (device L) and a remote device R (device R) that are connected by two-core bidirectional optical fibers F1, F2. The device L calculates the propagation delay amount τ1 of the fiber F1 from: the ratio between a propagation delay time difference T1 between pulse signals P1, P4 of the same wavelength λ 1  returned in reply after transmitting, to the device R, a pulse signal P1 of the wavelength λ 1  and a pulse signal P2 of a wavelength λ 2  different from the wavelength λ 1 , and a propagation delay time difference T2 between pulse signals P1, P3 of different wavelengths λ 1 , λ 2 ; and a proportional relationship with a round-trip delay time τud between the devices L and R. The device L transmits the pulse signals P1, P2 with a time difference td corresponding to a difference in calculated propagation delay amount τ1 between this time and last time such that the difference becomes zero.
