Abstract

A novel passive phase correction method for stable fiber transfer of radio-frequency (RF) signal is proposed and demonstrated. By employing only one local oscillator and two frequency mixers in the local station, an RF signal received by an optical remote antenna unit 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 single-mode fiber, effective cancellation of the RF signal’s phase jitter induced by environmental perturbations is achieved. The residual jitter is less than 1.33 ps (about 0.05 rad). The proposed scheme requires no active mechanism to compensate the fiber-length fluctuations, and is thus compact, cost-effective, and easy to implement.
