英文摘要	To achieve high-stability and high-precision dissemination of radio frequency signals over a long distance optical fiber link, a pure-electric phase compensation system is proposed. It can be easily modularized and achieve highly compensation speed and range. This system mainly uses two analog phase shifters to balance the phase fluctuation introduced by the round-trip fiber link. Due to the simple structure, it is easy to debug and test. By introducing the digital signal processing and proportion integration differentiation (PID) control algorithm, the system can effectively compensate the fiber-induced phase noise and ensure a high-accuracy frequency distribution. Finally, using this system in a 100 MHz frequency transfer experiment via 100 km optical fiber, an stabilities of 3.9??10-14/s and 1.1??10-16/4000 s are achieved. The experiment proves that this system is feasible in the long-distance radio frequency transfer and provides a technical support for the frequency synchronization needed in the cooperative working of remote stations, such as navigation, aerospace and space exploration. ?, 2015, Science Press.
