Effect of signal wavelength and aperture area of detector on performance of free space optical link

Bit error rate performance of a FSO link and visibility range are adversely affected by, harsh weather conditions, and atmospheric turbulence like fog, rain, clouds and dry snow. Wavelength of signal and aperture area of optical detector affects quality factor of receiver. This paper presents performance of FSO link with different wavelengths and different aperture area of optical detector. Effects of different wavelengths on visibility range and quality factor of optical receiver have been simulated. For simulation, license versions of OPTSIM 5.2 and MATLAB 6.00 have been used.
