Abstract
The effect of Mach-Zehnder modulator (MZM) direct current (DC) extinction ratio on single sideband (SSB) radio over fiber (RoF) link is analyzed and simulated, finite extinction ratio and drive signal unbalanced ratio of dual-drive MZM (DD-MZM) are considered. Our results show that power variation of target signal increase and harmonic suppression ratio decrease with the decline of extinction ratio. However, for a nonideal modulator with low extinction ratio, optimum drive signal unbalanced ratio could be applied to obtain a high quality microwave signal.
