Abstract

The free space optical communication system addressed as optical wireless communication has recently received huge attention. Communication acts as the possible way to address the link capacity and spectral efficiency issues. Due to the requirement of fundamental features like higher data rate transmission, improved data security and congestion-free transmission through the atmosphere, effective research interest is aroused in Free space Optic communication systems. As the Free space Optic technology exchanges a technological legacy with optical fibre communication, the Free space Optic links can deliver effective bandwidth. Even though it provides effective link reliability, the disastrous effect is faced due to the accordance of atmospheric attenuations like rain, snow, fog and so on. Hence, to promote effective data transmission, a hybridized model called spectrum slicing–wavelength division multiplexing–polarization division multiplexing (SS–WDM–PDM) is projected in this research work. The major objective of the projected work is to maximize the link capacity and enhance spectral efficiency. The attenuation noises like light rain, heavy rain, medium rain and light fog are considered to evaluate the outcomes of a Free space Optic communication system. The outcomes of the SS–WDM–PDM-FSO system are analyzed for numerous building heights and wind speeds for distance and received power. The parameters like an optical signal-to-noise ratio (OSNR), bit error rate (BER) and Q factor are contemplated to evaluate the performance. The simulation tool adopted to analyze the performance is MATLAB.
