Method and system for high-precision two-way fiber-optic time transfer
A method and system for high-precision two-way fiber-optic time transfer comprising pre-adjusting, including calculating a local timing signal adjustment amount for a first fiber-optic time synchronization unit and a second fiber-optic time synchronization unit, and the corresponding adjusting. and following steps including the two fiber-optic time synchronization units conducting two-way time transfer based on a time division multiplexing transmission over an optical fiber link. The present invention realizes high-precision fiber-optic time transfer by combining two-way time transfer and bidirectional time division multiplexing technique.
