Corrective chirp adding for minimizing distortion in Radio-over-Fiber System fiber optic line

Corrective chirp for distortion minimization in fiber optic line in Radio-over-Fiber systems is considered in the paper. It is suggested to use Mach-Zehnder modulator for corrective chirp adding. Corrective chirp is added by tapering the bias point of Mach-Zehnder modulator. Corrective chirp mathematical model is considered in the paper. Also mathematical model of the signal with corrective chirp that transmitted in Radio-over-Fiber systems is considered in the paper. Simulation model of suggested construction scheme of fiber optic section is considered. Experimental results of Radioover-Fiber system with corrective chirp is presented in the paper.
