Free space optical (FSO) link design under diverse weather conditions

摘要

This paper presents the link budget calculations for Free Space Optical (FSO) communication system under diverse weather conditions. It discusses various factors involved in the medium between the transmitter and receiver, which affect link budget calculations. For free space optical communication, atmospheric losses are the dominating factor in the link budget. These losses should be catered in such a way that sufficient power is available at the receiver to retrieve the information. It also describes the limitations of free space optical system under adverse weather conditions.
