Abstract
A full-duplex radio-over-fiber (RoF) link providing multiband wireless accesses including 20GHz, 40GHz and 60GHz millimeter (mm)-wave signal using a 10GHz RF signal source is proposed. According to our theoretical analysis and simulation of the transmission performance of the signal along the single mode fiber, the code form distortion caused by the sideband walk-off effect due to the fiber chromatic dispersion can be eliminated, and the degradation caused by the fading effect on the down-stream signal is removed by adjusting the relative phase shift between the two sidebands. The upstream signal carried by the optical carrier abstracted from the downlink signal is also immune to the code outline distortion. The numerical simulation results show that the 20km full-duplex RoF link with our generated optical mm-wave signal maintains good performance.
