Abstract
The need for communication with the least mistakes and smooth execution is a fast-developing interest of the present period. In optical communication, Free Space Optics (FSO) is one of the requesting fields as it gives more extensive transmission capacity, information security and has simplicity of establishment. FSO framework is license-free, effectively deployable, and gives a high information rate. Notwithstanding, turbulences in climate influences the exhibition of FSO. In the proposed model, Wavelength division multiplexing (WDM) is utilized with the FSO interface. A novel model is studied for multiple client free-space optical system (FSO) utilizing polarization shift keying (Pol-SK) modulation scheme with wavelength division multiplexers and demultiplexers. Bit error rate performance of Pol-SK modulation is investigated for different clients in the WDM-FSO framework and results are presented through BER analyzer. Theoretical examination of different schemes of modulation and numerical channel models for Pol-SK are clarified. The simulation of the WDM-based FSO framework has been tried under various climatic conditions like clear sky, light haze, hefty haze, light downpour, medium downpour and weighty downpour dependent on Bit error rate (BER) and fiber interface distance. Exploratory outcomes have been seen in the Opti wave Opti system software.
