Free space optical (FSO) communication is a growing technology to handle high data rate and it has very large
information handling capacity. However, the biggest bottleneck in FSO systems is the atmospheric effects that limit their use in
long reach applications. Research is consistently being carried out for merging different techniques which aim at reducing these
effects, however, they are less efficient during different weather conditions. Thus to make the previous system more efficient, a
work is proposed in this paper in which the multi-beam FSO is used instead of single-beam.
