Comparison in Behavior of FSO System under Clear Weather and FOG Conditions

Abstract

Free space Optical (FS0) communication has been emerged as a more conventional means of communication rather than the traditional optical communication. Its high speed of up to 2.5GHz and the license free long range operations makes its more superior system over other communication systems. Not only have these factors made it a better communication system but there are many other advantages of these systems like, small size, high bandwidth and low cost. Free space optical communication has some limitations also like its degradation in bad weather conditions. Weather effects the performance of the free space optical communication by means of scattering. In this paper we will design a FSO system which has range of 1 km and data rate of 2.5Gbps and check its performance in clear weather and fog conditions.
