Abstract-Free-space optical (FSO) communication is a cost effective and high data rate access technique, which has been proving itself a best alternative to radio frequency technology. FSO link provides high bandwidth solution to the last mile access bottleneck. However, for terrestrial communication systems, the performance of these links is severely degraded from atmospheric loss mainly due to fog, rain and snow. So, a continuous availability of the link is always a concern. This paper investigates the dreadful weather effects such as rain, fog, snow, and other losses on the transmission performance of FSO systems. The technique of using an array of receivers for improving the performance of FSO links is explored in this paper. It involves the deployment of multiple photo detectors at the receiver end to mitigate effects of various weather conditions. The performance of the proposed system is evaluated in terms of bit error rate, received signal power, Q-factor and height of eye diagram. The influence of various weather conditions of plain and hilly areas are taken into consideration and results are compared with conventional FSO links.

“…Whiteout conditions might attenuate the beam, but this problem for FSO systems can be coped with as the size of snowflakes is large in comparison to the operating wavelength [11]. The amount of attenuation in snow condition is 3 dB/km to 30 dB/km [6] Rain Condition: Rain has a distance-reducing impact on FSO, but still its influence is significantly less than that of other weather conditions.…”

“…In general, snow tends to be larger than rain. Whiteout conditions might attenuate the beam, but scattering doesn't tend to be a big problem for FSO systems because the size of snowflakes is large when compared to the operating wavelength [6]. The impact of light snow to blizzard and whiteout conditions falls approximately between light rain to moderate fog, with link attenuation potentials of approximately 3 dB/km to 30 dB/km.…”

-Over the last two and half decades Free Space Optical (FSO) communication is preferred over the radio frequency communication and microwave systems because of its license-free long-range operations. Also it is having many advantages like small size, high bandwidth, low cost and lease of deployment. Free Space Optical communication has few limitations also like beam dispersion, scintillation etc. A well known limitation of FSO is the effect of weather conditions on it. In this paper we have designed a 2.5 Gbps FSO system and presented analysis of 2.5 Gbps FSO system with different weather condition by distance of 9 km. From the result it is clear as we move from clear weather to heavy fog Q factor as well as transmission range will decrease.
