Free space optical communication (FSO) is a promising technology where optical fiber installation is not feasible. Performance of FSO system is affected by atmospheric attenuation caused by changing weather condition, such as haze, fog, snow, rain, etc., and scintillation induced by atmospheric turbulence. This article demonstrated the performance of coherent optical orthogonal frequency division multiplexing FSO (CO-OFDM FSO) system under the atmospheric turbulences and haze weather condition which performs better than traditional direct detection system. System is analyzed for different number of subcarriers under the influence of moderate to strong turbulence by adjusting the value of refractive index structure parameter. There is a degradation of 2–8 dB in SNR from moderate to strong turbulence up to the range of 30 km.
