AB  - Free-Space Optical (FSO) is considered to be one of the key technologies for high-speed and
large-capacity wireless communications. The reliability and availability of the optical path for wireless
broadband communications is influenced by the local weather conditions. The countries of the Middle East
including Iraq suffer from frequent Sand and Dust Storms (SDS) reach the maximum during the period
(2010-2012). In the present study, optimized design was implemented to investigate the fluctuations of
transmitted optical signal along the path and determining system performance. By using (OptiSystem7)
software, simulation employs with Multiple-Input Multiple-Output (MIMO) technique. The obtained results
show that bit error rates BER goes on decreasing when the signal to noise ratio is decreased at the beginning
of 2010 then increasing the BER performance for next season's leads to the reduced received optical power due
to weather turbulence effect. The results presented in this study are useful for designing a stable FSO system
for dry and dusty regional environments.
