Analyzing the Internal Parameters of Free Space Optical Communication

Free Space Optical (FSO) Communication is an efficient technology as it offers higher signal bandwidth and less power for transmission. There are some internal parameters on which the performance of the FSO communication depends such as beam divergence, wavelength. The purpose is to optimize these factors to achieve the maximum output and throughput. In this paper FSO model has been designed using PIN Photodiode and Avalanche Photodiode(APD) at receiver’s side. Using the model, Q-Factor has been estimated for different beam divergences and wavelengths at varying bit rates. The results have been compared and analyzed for the two types of photodiodes.
