Abstract

We study the noise due to fiber dispersion in a scenario of phase dithering to suppress Stimulated Brillouin Scattering (SBS) in microwave fiber optic links. A novel large signal analysis is given to calculate the logarithm signal spectrum. Our experiment and numerical analysis show that, besides the random noise due to phase modulation, there are discrete spectral lines spaced at dither rate in the detected signal, which may act as interference. Our analysis reveals that these discrete spectral lines are caused by sharp rising/falling edges in the PRBS used for phase dithering. The study should also be useful to analyze noise in digital phase modulated microwave fiber optic system.
