An rf dissemination system using an optical fiber link has been developed. The phase noise induced during optical fiber transmission has been successfully cancelled using what we believe to be a novel fiber-noise compensation system with a combination of electrical and optical compensations. We have performed rf transfer in a 114 km urban telecom fiber link in Tokyo with a transfer stability of 10(-18) level at an averaging time of 1 day. Additionally, a high degree of continuous operation robustness has been confirmed.
已经开发出一种使用光纤链路的射频分配系统。我们成功地使用一种新颖的光纤噪声补偿系统,结合电气和光学补偿,抵消了光纤传输过程中产生的相位噪声。我们在东京的 114 公里城市电信光纤链路中进行了射频传输,在 1 天的平均时间内达到了 10^(-18)水平的传输稳定性。此外,还确认了高度的连续运行鲁棒性。
