Analysis of the effect of haze on free space optical communication in the Malaysian environment

摘要

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. Deployment distance of less than 1km can reduce the effect of atmospheric attenuation. These challenges limit FSO to the short distance application.
