Abstract :
A simple, compact, cost-effective post-phase correction method for stable fiber transfer of RF signal is proposed and demonstrated. By employing only one LO source and two frequency mixers, a RF signal is transmitted to the local station with very small phase jitter. An experiment is performed. When a 6-GHz RF signal is delivered through a 20-km SMF, effective cancellation of the phase jitter induced by the environment perturbations is achieved. The residual jitter is less than 0.07 rad.
