In this paper, we demonstrate a radio frequency dissemination system via fiber link. An electric phase-shifter is used to active compensate the phase error in the transfer process. Furthermore, an improved error signal extraction component is used to extract the phase error induced via the fiber link. The system can compensate large phase range fluctuation rapidly and precisely. An experiment has been demonstrated with this structure to disseminate a 100 MHz frequency through 100 km. The relative frequency stability is 3 × 10(-14) at 1 s and 3 × 10(-17) at 4000 s. It means this scheme can be used to transfer the most stable microwave sources through fiber link.
