Abstract
In this paper, the performance study of free space optical (FSO) systems is completely analyzed, when the atmospheric channel is affected by atmospheric conditions such as haze and fog. Comparison of the FSO system’s performance with semiconductor optical amplifier (SOA) and erbium doped fiber amplifier (EDFA) under the influence of haze and fog is studied. The received power, eye diagram, and quality factor (Q-factor) are the performance metrics taken into consideration in this paper. Through simulations, it is demonstrated that the fog has a detrimental effect on FSO system performance, when compared with the haze. Further, the distance over which the FSO system can work reliably will be improved by using EDFA in the place of SOA for performing pre-amplification and post-amplification.KeywordsFree space optical (FSO)Atmospheric channelErbium doped fiber amplifiers (EDFA)Quality (Q) factorSemiconductor optical amplifiers (SOA)Fog and haze
