Abstract

In order to meet the demand of high precision remote traceability, a remote traceability system based on optical fiber was designed and implemented. The system traced the time of the local time to the remote high-benchmark time source based on the high precision and high stability of two-way time transfer via optical fiber, and adopted the dual backup mechanism of primary and standby circuits to ensure its reliability. Experiment showed that the system can achieve the traceability effect with the time difference less than 2 ns and the daily frequency stability within 7×10^-15.
