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^-17/10^4 s are obtained for a 10 km dissemination. This low cost and scalable method can be applied to a large-scale frequency synchroniza- tion network.展开更多
