Abstract :
In this paper, we present a novel scheme using dual-wavelength lights to suppress the nonlinear intermodulation distortion in intensity-modulated radio-over-fiber link both theoretically and experimentally. More than 26 dB suppression of the third-order intermodulation distortion (IMD3) is achieved after 5.1km single mode fiber transmission; and the error vector magnitude of the proposed scheme is reduced from 18.26% to 8.06% after linearization.
