Effect of Atmospheric Weather Condition on the performance of FSO

Abstract

Free Space Optical is a data transmitting method, which requires a point-to-point connection for reliable communication. It is the transmission of data through unguided propagation media. FSO communication operates 10 Gbps with a high data rate up to a few kilometers distance. Despite all the advantages, the performance of the FSO system is degraded by atmospheric turbulence such as absorption, scattering, etc. This investigation deals with the performance analysis of atmospheric attenuation over different atmospheric weather conditions. Here in this work, comparing the attenuation coefficient in different atmospheric conditions for the FSO system. The objective of this work is to produce an analysis result of the different weather attenuations, due to the rain, and hazard, that affect the FSO link. The suitability of three optical transmission Windows, those are 850nm, 1310nm, and 1550nm is analyzed, and compared with the previous works. In the proposed work, the Weather Forecast database has been used to take as an input, which would make the visibility model more accurate. The mostly used three wavelengths are used in the proposed model. Subsequently, the simulation software has also been used to extract the output parameters, which makes this model more accurate.
