This work introduces a scheme for transmitting dual-polarized quadrature amplitude modulated (QAM) signals through a sixteen-channel wavelength division multiplexing (WDM) and free-space optics (FSO) communication link, achieving a transmission rate of 120 Gbps per channel. The system's performance is evaluated by calculating atmospheric attenuations in different weather conditions and compared to previous reports.
This work presents the dual-polarized quadrature amplitude modulated (QAM) signals transmitted via a sixteen-channel wavelength division multiplexing (WDM) and free-space optics (FSO) communication link. Through an FSO link up to 98 km, it achieves a transmission rate of 120 Gbps per channel. The system's performance is evaluated by calculating atmospheric attenuations in clear, hazy, rainy, and fog situations. Optisystem, an optical network design tool, examined the proposed link. Bit error rate, received signal constellation, error vector magnitude, and geometric loss for various FSO channel lengths were calculated. According to the results, the system can successfully transmit a data rate of 1.92 Tbps over the 98 km range of the FSO link under clear weather, 18.5-3.8 km under haze, 6.25-2.3 km in the rain, and 4.55-2.15 km in fog conditions. Comparing results to previous reports showed that the proposed system was found to be better in dynamic atmospheric circumstances.
