Improving of Wavelength Division Multiplexing Based on Free Space Optical Communication via Power Comparative System


In this paper, the performance of wavelength division multiplexing based on free space optical communication is enhanced via the power comparative system (PCS). The proposed system is simulated by OptiSystem 7 and investigated under three main conditions, namely, without missig–pointing losses (MPL), with MPL and with MPL and PCS. In addition, three weather conditions are adopting in this work, namely, very clear, clear and hazy weather. According to the results, the MPL caused degradation in the maximum achieved link range to the ratio of 44.06%, 41.66% and 27.77% for the weather condition of very clear, clear and haze, respectively when compared with the system without MPL. While the achieved link range of the proposed system is enhanced when the PCS is employed by 45.45% for very clear weather, 42.85% for clear and 23.07% for hazy weather, when compared with the system with MPL. Furthermore, the performance of the proposed system is investigated and compared with the previous work under the same weather condition as well as compared with Kim model and show good agreement with it.
