“…The distortions of front-wave can be observed as intensity changes referred as scintillation. Aerosols, moisture, temperature and pressure fluctuations produce variations of the air density and thus also its refractive index [3]. Air eddies can bend the optical path if their size is larger than the beam diameter (Fig.…”

“…The range of the link for evaluating the performance is chosen as 500m and the transmission wavelength chosen for the working of laser is 1550 nm which is the 3rd optical window of wireless transmission. It is chosen to work on this wavelength as the functioning of FSO link is more robust and safe for human eye at this value [2][3].…”

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.

“…Attenuation produced by air conditions reduces the wireless channel's range and capacity [10]. Therefore, limiting the places and periods where the 302 free space optic link can be used will limit its potential [4] free space optic technology relies on careful weather analysis and the use of different optical windows to limit the effects of rising signal attenuation for its bandwidth to be maximized [11].…”

Gigabit - per - second data speeds can be achieved via free space optics (FSO) lines, which needless system complexity. On the other hand, the link's availability across a wide range of atmospheric circumstances is a major worry. As a result of the increased signal attenuation caused by the linkages being weather - dependent, their efficiency decreases. Up to 70 dB/km of attenuation can be caused by bad weather on a 500 - meter free space optics link. In this work, transmission windows of 1310 nm, 850 nm , and 1550 nm are analyzed and compared using the free space optics link. by using the Simulation program o pti system such as the q uality factor, the minimal bit error rate (BER), and the e ye diagram is taken into account. Analyzer findings are compared to establish the optimal wavelength for a transmitter under poor weather conditions.
