Joint Time and Frequency Dissemination Network Over Delay-Stabilized Fiber Optic Links

Joint Time and Frequency Dissemination Network Over Delay-Stabilized Fiber Optic Links

A precise fiber-based time and frequency dissemination scheme for multiple users with a tree-like branching topology is proposed. Through this scheme, ultrastable signals can be easily accessed online without affecting other sites. The scheme is tested through an experiment, in which a modulated fre...
