Comparative Analysis of Point to Point FSO System Under Clear and Haze Weather Conditions

Free space optics (FSO) is an optical mean of communication where free space acts as a medium between transmitter and receiver and both should be in the line of sight for successful transmission of signal. Free space can be air, outer space, or vacuum. This system is economically beneficial than other systems and deployed in a matter of hours. This system poses great advantages like high bandwidth. There are some factors which can affect the transmission in FSO. Presence of foreign elements like rain, fog, and haze, physical obstruction, scattering and atmospheric turbulence are some of these factors. In this paper, two FSO links are designed and compared using WDM to study under clear and haze weather conditions. The present system supports the transmission up to longer link distances of 350 and 47 km under clear weather and haze conditions respectively.
