PROJECT TITLE :
Joint Time and Frequency Dissemination Network Over Delay-Stabilized Fiber Optic Links
A precise fiber-primarily based time and frequency dissemination scheme for multiple users with a tree-like branching topology is proposed. Through this theme, ultrastable signals will be easily accessed on-line without affecting different sites. The theme is tested through an experiment, in which a modulated frequency signal and a synchronized time signal are transferred to multiple remote sites over delay-stabilized fiber optic links that are over 50 km long. Results show that the relative stabilities are at 1 s and at ten four s. Meanwhile, compared with each website, time synchronization precision is less than 80 ps. These results will pave the method to sensible applications in joint time and frequency dissemination network systems.
