Analysis of the propagation different wavelengths (632.8, 785, and 1330 nm) in Free Space Laser Link at Babylon City


Attenuation due to Aerosols, It restricts the distance of free space optical communication systems (FSO) and limits the availability for line -sight terrestrial link. This work is focused on the effect of Aerosols on the FSO link. The attenuations was studied in the Babylon city in the aerosols phenomena for three selected wavelengths (632.8, 785, and 1330 nm) for horizontal transmitting range (10 m-3 km).The results show the system availability as a function of the range, and indicate that FSO systems can be deployed with reliability in Babylon city of Iraq.
