In this paper we have analyzed free space optical communication system affected by atmospheric attenuation in spatial diversity. Spatial diversity means different numbers of transmitters and receivers in FSO link. We have taken five configurations of FSO which are: 1x1, 2x2, 4x4, 8x8, and 16x16. 2x2 configuration means there are 2 transmitters and 2 receivers in FSO link. FSO link is analyzed at 1550 nm wavelength for different values of input power. Attenuation is taken as clear (0.43 dB/Km), haze (4.3 dB/Km) and fog (43 dB/Km). Maximum optical range of FSO link is calculated for constant Q factor of value 5.17. Eye diagrams are generated to produce the desired results.
