Abstract: In this paper the design and simulation of wireless optical communication system (FSO) through the use of software (Optisystem 7.0) and study the effect of fog on the performance of communication system (FSO), where the fog attenuation calculate wavelengths are (1550 nm, 784nm) and the types of fog (thin Fog and The dense fog and very dense fog). And also studied the effect of the attenuation of the fog on the transmitted Laser Power and transmitter range (propagation distance) where they were taking five different values of transmitted laser power They (50mw, 40mw, 30mw, 20mw, 10mw) and calculate the maximum send range each value of the values of the power transmitted under the effect of Fog attenuation of wavelength (1550nm, 784nm).
