چکیده
Free Space Optical (FSO) communication is a very recent and emerging technology to establish broadband wireless data transmission system using modulated optical beams. The adoption of FSO system is mainly needed when any physical connection between the transmitter and receiver is practically impossible and where high bandwidth data transmission is expected. The performance of FSO communication technology is highly dependent on atmospheric attenuation which is related to the visibility of the different weather conditions as well as operating wavelengths. This paper presents our study about the effect of visibility as well as operating wavelengths on atmospheric attenuation in different weather conditions for point-to-point free space optical link. Moreover, it also discusses the methodology to find out the optimum link distance for point-to-point FSO link which will be operated in different weather conditions. It is found that, atmospheric attenuation is changed with the change in weather condition as well as operating wavelengths.
