Performance Characterization of the Free Space Optical Communication System using Laser at Different Wavelength

FSO is a communication process that uses light containing information to travel in free space to exchange data between two or more points. Use of Multiple TX/RX in the FSO system increases the performance of FSO system under different atmospheric disturbances. This paper analyzed the performance of TX/RX FSO system using Q factor, Bit Error Rate (BER) etc. The Free Space Optical link is designed and simulated using OptiSystem. Free space optical (FSO) communication has emerged as a viable technology for broadband wireless applications which offers the potential of high bandwidth capacity over unlicensed optical wavelengths. This research considering the first step to create a scientific base for optical and electro-optical designs operating in communication field. In this research paper FSO link is optimized for operation under different wavelength and simulated on different parameters like Q-factor, eye diagram. Simulation results provide proposed FSO link for a long range communication link more than 1000 meter with increased data rate of up to Gbps. Also the performance of proposed link can be improved for sustainability of communication channel in normal and critical weather condition, which can be evaluated on the basis of parameters like Q factor, BER , eye diagram and eye height.
