摘要

We demonstrate a new fiber-based radio frequency (RF) dissemination scheme suitable for a star-shaped branching network.Without any phase controls on the RF signals or the use of active feedback-locking components,the highly stable reference frequency signal can be delivered to several remote sites simultaneously and independently.The relative frequency stabilities of 6 × 10-15/s and 7 × 10 17/104 s are obtained for a 10 km dissemination.This low cost and scalable method can be applied to a large-scale frequency synchronization network.
