Radio over Free Space Optical Communication System Experimental Setup and Performance Analysis

Experimental study of RF over turbulent free space optics (FSO) channel on signal transmission was conducted in this paper. The results revealed the possibility of applying FSO links to transmit RF signals and using them as guidelines to design, predict and assess (DWDM) – Radio over FSO system that can transmit multiple signals of RF. In addition, modeling for analyses of the system is performed for recognizing the main parameters in assessing RF signal transmission function by applying the FSO links. By a simple estimation formula, results of our study confirmed the possibility of scintillation effect on system performance through estimation on RF over FSO system and obtaining satisfactory results through comparison of theoretical and experimental data under different turbulence conditions.
