| Summary: | Free Space Optical (FSO) has a very good potential alternative
solution to Radio Frequency (RF) to provide high terrestrial wireless communication.
In tropical region, the only drawback of FSO is atmospheric attenuation
due to mainly haze and rain. This study investigates the performance of FSO
system over link distances that ranges between 9 km to 12 km as the average
visibility in Kuala Lumpur, Malaysia is 10 km. Two models used to predict the
atmospheric attenuation, namely Kruse model and modified Kruse model. These
models are valid to predict the haze attenuation for visibilities that range between
9 to 12 km. The modified/corrected Kruse model shows some limitations in the
prediction of haze attenuation over longer wavelength. However, the study indicates
that attenuation due to haze is low, while air quality in Kuala Lumpur,
Malaysia is acceptable. As the size of haze particles varies from 0.01 to 1 μm,
the longer wavelength is preferable as 1550 nm to enhance FSO performance
compared to 850 nm and 600 nm wavelengths. Thus, the longer wavelength is
the optimal choice to enhance the FSO performance as it caused low scattering. |
