Abstract
In this paper, we investigate the transmission of a 100 Gbit/s signal with 0.1THz carrier frequency using radio over fiber (RoF) for a fiber length of 50km. In our study, the impact of chromatic dispersion on the wireless signals transported through the fiber link and its mitigation using different dispersion compensation techniques are discussed. The techniques discussed here includes the optical single sideband transmission using dual electrode Mach Zehnder modulator, external filtering using FBG and compensation using chirped fiber grating. We also evaluated the performance of the three compensation techniques by plotting the eye diagram. The results clearly depict that compensation using chirped grating is the best among the three methods. The investigation is done on detailed simulative analysis using Optisystem.
