| Summary: | Free Space Optics is a promising optical wireless
technology in broadband networks. It uses laser as a medium
of transmission between two transceivers. In tropical
climate, haze is one of the weather phenomenons which
reduce the visibility. Low visibility increases atmospheric
attenuation and reduce the availability of optical signals for free space optics (FSO) links. In this paper, the effect of atmospheric attenuation due to haze on free space optical
link in tropical climate has been demonstrated. The analysis
based on one year measured visibility data in Malaysia.
Predicted attenuation varies with different wavelengths.
Thus, two wavelengths were considered. The predicted
atmospheric attenuation was compared across the two
wavelengths. Measured visibility data and predicted
attenuation were used to estimate the link availability of free space optical links. From the results higher wavelength has lower attenuation compare with lower wavelength. This
paper indicates useful information for the deployment of
FSO link in tropical climate. |
