| Summary: | This paper presents the effect of atmospheric attenuation during hazy days for free space optical (FSO)
communication in point-to-point connection. The analysis focuses on scattering coefficient and atmospheric
attenuation effects on low visibility, which falls in the range of 1.8 km to 4.5 km. The performance comparison
is also done for the wavelength of 850 nm and 1550 nm. The result shows that the performance of 1550 nm is
better than 850 nm in both performance parameters. As the link range between transmitter and receiver
increases, the atmospheric attenuation increases too. Using small divergence, small transmitter aperture, and
large receiver aperture and deployment distance of less than 1km can reduce the effect of atmospheric
attenuation. These challenges limit FSO to the short distance application. |
