Fiber-based Radio Frequency Dissemination for Branching Networks with Passive Phase Noise Cancellation

We demonstrate a new fiber-based radio frequency dissemination scheme for branching networks. Without any phase controls on RF signals or usages of active feedback locking components, the highly stable reference frequency signal can be delivered to several remote sites simultaneously and independently. Relative frequency stability of 6E-15/s and 7E-17/1E4s is obtained for 10km dissemination. The proposed low cost and scalable method can be applied to some large-scale frequency synchronization networks.
