Now-a-days, Free Space Optical (FSO) Communication is one of major hot topics in the world of optical & wireless communication. FSO communication is based on optical communication with only difference that here the light signal which carries the information is not confined in to physical channel such as optical fiber. This paper is focused to carry out the investigations of free space optical transmission system under the impact of different atmospheric attenuation factors. In this paper A 10 Gbps data is transmitted through free space optical link of 1 km and the performance is measured in terms of SNR, BER and eye diagrams. Further the role of modulation format is also investigated.
