Optical Wave Communication In Free Space Under Different Weather Conditions

Abstract

The use of laser light for communication is referred to as free space optics. Between the transmitter and the receiver, Free Space will operate as a conduit. This open-source space optics system will provide information on a variety of weather events. Free space communication is a type of optical communication that operates at near-light speed. Air, outer space, or vacuum are all examples of free space. This technology is less costly than others and may be installed in a matter of hours. This method offers a number of benefits, one being the fact that it saves a lot of bandwidth. FSO distribution can be influenced by a number of variables. Rain, fog, and haze, as well as physical barriers, diffraction, and environmental turbulence, are examples of foreign particles. Turbulence is one of these characteristics. In exploring clear and hazy weather scenarios, current technology can broadcast up to extended connection distances of 350 metres and 47 kilometres. As a result of differential heating, the refractive index of the air varies at random. The received signal intensity fluctuates as a result of these oscillations, the beam refocuses, and the transmitting beam widens towards the end. The bit error rate (BER) and maximum quality factor (Q) of any system help to determine transmission quality. The BER receiving data increases as attenuation and transmission power are reduced. The FSO link's performance, which is to be quantified in receiving power, BER, and can also be used to determine the signal's noise.
