Abstract


This study aims to study the compensation of different atmospheric attenuations of eleven-channel dense-wavelength division multiplexing (DWDM) over free-space optics (FSO). The channels operate over (1561.42 nm, 1559.79 nm, 1558.17 nm, 1558.55 nm, 1554.94 nm, 1553.33 nm, 1551.72 nm, 1550.12 nm, 1548.51 nm, 1546.92 and 1545.32 nm) wavelengths that have separated based on the traditional International Telecommunication Union (ITU) grid. The performance of an eleven-channel DWDM system is evaluated in FSO link under the clear air, haze and rain atmospheric attenuation based on low pass raised cosine electrical filter at the receiver. In the experiments, the system transmits 110 Gbit/s for FSO distances 9500 m, 3000 m and 2500 m in superbly clear air, haze and heavy haze atmospheric attenuations, respectively. Over different atmospheric attenuations, we evaluated our system performance using BER, eye diagram and the quality factor (Q-Factor).
