The effect of haze attenuation on Free Space Optics Communication (FSO) at two wavelengths under Malaysia weather
Free Space Optical FSO is a promising optical technology that has a great chance of complementing the traditional wireless communication. It offers unlicensed, higher speed, broader, unlimited bandwidth and excellent security. However, the quality of FSO links is greatly affected by weather co...

| Summary: | Free Space Optical FSO is a promising
optical technology that has a great chance of
complementing the traditional wireless
communication. It offers unlicensed, higher speed,
broader, unlimited bandwidth and excellent security.
However, the quality of FSO links is greatly affected
by weather conditions and link distance. In the
tropical regions, the quality of the FSO links is
affected mainly by rain attenuation while the air
quality is presumed to have little or no impact.
However, a state of emergency has consecutively been
declared in some part of Malaysia during the past
three years due to high air pollution index (API).
Since the range of FSO link is limited by air pollution,
haze attenuation must be considered as one of the
important factors in FSO link design. The aim of this
paper is to provide an analysis and simulation of the
FSO link with real data from Meteorological
Malaysia department (MMD) on haze weather under
two different wavelengths 850nm and 1550nm. This
paper will discuss the different rate of attenuation
operating in the medium between transmitter and
receiver and their impact on the link margin
calculation. In addition, it will evaluate the maximum
distance link for wavelengths and consider the
different visibility under the attenuated weather. |
