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. © 2015 Chinese Optocs Letters.
