Effect of rain & haze on availability of terrestrial free space optical link under tropical weather conditions
Availability is a major concern to measure the QoS of Free Space Optical (FSO) communication link. In tropical areas, rain is the most dominant factor affecting the FSO link availability; whereas haze has no significant impact on FSO link availability compare to rain. In this paper,availability as...

| Summary: | Availability is a major concern to measure the
QoS of Free Space Optical (FSO) communication link. In
tropical areas, rain is the most dominant factor affecting the FSO link availability; whereas haze has no significant impact on FSO link availability compare to rain. In this paper,availability assessment of FSO was examined based on
predicted atmospheric attenuations due to rain and haze.
The predicted atmospheric attenuations due to rain and haze
were obtained using rain rate (mm/hr) and visibility (km)
data measured in Malaysia. The effect of individual weather
phenomena was analyzed and availability performance of
FSO was evaluated. Combine effect of both rain and haze
was also demonstrated using cumulative distribution
function (CDF) of both atmospheric attenuations due to rain
and haze. This study provides recommendations to FSO
researchers in general and local telecom service provider in
particular about possible availability figures that can be
useful for deployment of FSO system over one kilometer link
distance. |
