Abstract: This paper presents, for the first time, the rain effect upon FSO link system in a tropical region. This region which suffers from a high rain density requires further understanding and analysis in FSO propagation, due to the fact rain has been one of the major and classical contributors to atmospheric attenuation. Investigation of local rain pattern and estimation through simulation, a prediction of the rain density level which could impair the link was carried out. In this work, a local rain model was introduced and analyzed. A sample was collected in Perlis state, and was provided by the Malaysian Meteorological Department (MMD). Theoretical analysis was used to determine the scattering coefficient, atmospheric attenuation and total attenuation. On the other hand, simulations using OptiSystem software were also executed in order to analyze the FSO performance due to atmospheric attenuation. Based on this proposed model, the maximum threshold rain level was estim!
ated at a fixed distance, while other parameters which could improve the link were also proposed. Through this study, several parameters such as beam divergence, aperture size and receiver sensitivity were identified to to be critical in improving the quality of FSO transmission.
