摘要

本文报道了北京地区100公里城域光纤链路的稳定射频传输实验。连接大牛坊和方庄的链路由两条平行的50公里暗光纤组成，总损耗为31 dB。在我们的稳定光纤射频传输系统中设计了双锁相环(双锁相环)结构。测量到的2.4 GHz射频信号传输系统的分数频率稳定性(ADEV)接近$1.7\乘以10^{-14}@1 \mathrm{s}$和$2.5\乘以10^{-17}@10000\ \mathrm{s}$。

Field Trial of Stable Radio Frequency Transfer System in 100 km Metropolitan Optical Fiber Link

We report on a stable radio frequency (RF) transfer experiment via 100 km metropolitan optical fiber link in Beijing area. The link connecting Daniufang and Fangzhuang is composed of two parallel 50-km dark optical fibers with a total loss of 31 dB. The dual phase locked loops (dual-PLL) configuration is designed in our stable fiber-optic RF transfer system. The measured fractional frequency stability (ADEV) of 2.4 GHz RF signal transmission system approaches $1.7\times 10^{-14} @1 \mathrm{s}$ and $2.5\times 10^{-17} @10000\ \mathrm{s}$.
