In this paper, we demonstrate a cascaded transfer of optical frequency with a relay station
over a fiber link. The station is outfitted to cascade numerous lines with independent phase …

We demonstrate optical-carrier transfer over a 112-km single-span urban fiber link. By
actively compensating the phase noise induced along the fiber link, a noise suppression of …

In this paper, we demonstrate a wavelength division multiplexing (WDM)-based system for
simultaneously delivering ultra-stable optical frequency reference, 10 GHz microwave …

为了保证长距离多站点间的高精度时间同步, 在利用双向时间比对法实现高精度长距离时间同步
的基础上, 提出了一种利用一个波长信道同时对1 PPS (pluse per second) 信号 …

Abstract We demonstrate a 300-km+ 200-km cascaded coherent phase transfer via fiber link.
The transfer is divided into a 300-km span and a 200-km span with independent phase …

We demonstrate a coherent phase transfer via a 224 km cascaded fiber link comprising two
112 km links stabilized by two phase-locking loops, respectively. The optical signal is …

In this paper, we present a high-precision optical frequency noise detection and comparison
technique using a two-way transfer method over a 260 km field fiber link. This method allows …

We demonstrate a novel polarization control system based on a gradient descent algorithm,
applied to a 450-km optical frequency transfer link. The power of the out-loop beat note is …

摘要利用西安和咸阳之间的电信省级骨干光纤网构建了210km 的光学频率信号传递测试链路,
链路损耗为0.23 dB/km. 实验中采用可搬运, 基于光纤干涉仪, 线宽约为200 Hz …

In this study, a sliding mode control (SMC) algorithm was proposed based on a novel
reaching law to solve the nonlinear disturbance problem of a ground-based laser …
