RF Transfer by Optical Comb Over 50-km Fiber Link With $4.7\times 10^{-18}$ Instability

Autor: Jianxiao Leng, Guoyong Luo, Dawei Li, Shanglin Li, Cheng Qian, Jianye Zhao

Publikováno v: IEEE Photonics Journal, Vol 8, Iss 1, Pp 1-9 (2016)

A radio-frequency (RF) dissemination system using an optical comb over a 50-km fiber link has been demonstrated in this paper. An optical filter is utilized to suppress the dispersion influence of the optical comb in the transfer fiber link. The comp
