In this paper, the Optical Wireless Communication (OWC) channels for different optical filters are analysed and compared with their previous model. Performance analysis is done using different optical filters namely Bessel, Trapezoidal, Gaussian and Fabry Perot optical filters. The results have presented maximum quality factor compared to the previous model in terms of both optical range and beam divergence. The proposed model has achieved maximum quality factor with different optical filters in terms of optical range, transmitter and receiver aperture diameters. It is found that the maximum quality factor can be achieved using Gaussian optical filter in comparison with different optical filters. The entire numerical results have been taken by optical communication system design software product by the optiwave team.
