FSO (free-space optics) is a new technology used to solve last mile problem in point-to-point communication. As name indicated, FSO link is a seamless communication link using air as a medium for transmission of optical information. For successful transmission, medium should be free of attenuation caused by different weather conditions like rain, haze, fog. In this paper, analysis of FSO systems has been done using two 32-channel WDM systems and then compared at a constant data rate of 2.5 Gbps. The system with single laser outperforms the system employing an array of 32 CW lasers in terms of link distance under different rain conditions.
