A dispersion‐free multi‐access RF dissemination link with phase jitter compensation

A dispersion‐free scheme for stable multi‐access radio frequency dissemination in a fibre loop link is proposed and demonstrated. The phase jitter and dispersion‐induced power fading are suppressed simultaneously by transmitting different single‐band signals in opposite propagating directions. Exper...

Zusammenfassung:A dispersion‐free scheme for stable multi‐access radio frequency dissemination in a fibre loop link is proposed and demonstrated. The phase jitter and dispersion‐induced power fading are suppressed simultaneously by transmitting different single‐band signals in opposite propagating directions. Experimentally, a 2.5 GHz radio frequency signal is steadily transmitted to different remote sites, with phase deviations less than 0.6 ps over 15,000 s.
