Significance and Limitations on Free Space Optical Communication Using Wavelength Division Multiplexing (WDM)

Dealing with wireless communication has been one of the most significant milestones in the history of technology. Free Space Optics is one of the leading wireless communication technologies related to secure data transfer in modern times as well as providing communication flexibility by making it more complex compared to Optical threads. In this paper, the significance of the FSO and its various variables in the various models are presented. Also, free space communication is done using Wavelength division multiplexing (WDM). The behavior of system has been observed for different attenuations in the propagation medium. Simulation is done with the help of Opti system software.
