Abstract. We present experimental and theoretical results on signal transmission in analog fiber-optic links (AFOLs) with direct or external RF/microwave modulation of laser light intensity, transportation of the optical signal through a fiber and direct detection of the optical signal by a photodiode at receiver end of the fiber. We consider in detail the linear and nonlinear signal distortions caused by the group velocity dispersion of light waves in the optical fiber, by the frequency chirp of light produced by directly modulated semiconductor laser and by the intrinsic nonlinearity of electro-optic Mach-Zehnder modulator. Theoretical calculations are in a good agreement with the experimental results and will be useful for the engineering design of analog fiber-optic links.

Keywords: analog fiber-optic links, frequency chirp of laser light, dispersive signal distortions, Mach-Zehnder modulator
