摘要： A method and a system for fiber-optic time transfer in the field of fiber-optic time and frequency transfer. The system for high-precision long-distance distributed fiber-optic time transfer is composed of a first clock source, a first fiber-optic time transfer unit, N relay and user units, M bidirectional optical amplifying units, a second fiber-optic time transfer unit and a second clock source. Each relay and user unit can obtain timing signals synchronized with the first clock source according to the time interval between the received forward and backward timing signals and realize distributed fiber-optic time transfer while realizing the optical-electric-optical relay of the forward and backward transmitted optical signals. The invention makes the bidirectional time signals pass through the same link to ensure maximum symmetry of the main link bidirectional delay; the effect of multiple optical amplifications of noise such as Rayleigh scattering on the stability of the fiber-optic time transfer is effectively avoided by the optical-electric-optical process; the distributed time transfer is realized by the bidirectional timing signal time interval received by the relay and user units.
