In radio-over-fiber (ROF) systems, optical carrier is modulated by the electrical signal and thus, converts the electrical signal to optical domain. This leads to the generation of up-converted signal bands. Although modulation is a necessary process for the faithful transmission of a signal, but it also degrades the modulated signal by generating distorted sidebands which causes reduction in the dynamic range of the system. Dispersion originated from the transmission fiber and other optical devices also change the phase relationship between the optical carrier and the modulated sidebands. This causes degradation of the modulated signal due to power fading. Mach-Zehnder modulator (MZM) is the most preferred modulator used in RoF systems. The performance of RoF system depends upon various parameters of Mach-Zehnder modulator (MZM) like RF bias, bias voltage, extinction ratio and insertion loss. In this paper the behavior of Lithium Niobate (LiNbO3) MZM is studied on various bias and extinction ratio ranges and a particular bias and extinction ratio is fixed at which the proposed ROF system gives the optimum results.Keywords
