Abstract—In recent years, free space optical communication (FSO) has received considerable attention as a cost-effective, free-to-license and broadband approach to high data rate applications. However, the performance of the FSO connection suffers greatly from fading caused by the disturbance caused by different weather conditions. The weather considers a worthy influence on the laser beam to transmit over the atmosphere. The attenuation weather results in the quality of the receiver signal. This paper investigates the quality of the FSO communication system under foggy weather conditions. The analysis of the system based on the measured receiver signal, bit rate error and signal to noise ratio in an optical communications link. 

Index Terms—FSO, optical communications, OptiSystem 7.0, atmospheric attenuation, SNR, BER.
