Abstract

Free space optics communication (FSO) system can be considered as the fibreless fiber optic, using the atmosphere as its transmission medium. FSO offers the flexibility and low cost solution for high bandwidth communication and optical connectivity especially in urban and metropolitan areas. Using the atmosphere as a communication medium FSO is exposed to damaging effects caused by bad weather and atmospheric conditions. These condition triggers some unwanted consequences ranging from attenuation scintillation etc. Simulations are made to demonstrate and present the extent of attenuation and other elements based on simulated condition and predetermined parameters. Simulation using measured parameters instead of estimation is important to gain certain understanding and some level of estimation regarding to the pulse behavior in free space. Using MATLAB as the simulation platform and the help of sufficient experimental or measured parameter, an accurate model can be obtain and studied. In order to gain some level of prediction of the likelihood and behavior of the propagating light pulse in the atmosphere and to further improve FSO performance.
