Design of novel hybrid WDM/multiple-beam FSO system to improve the link length in rainy season

摘要

As single laser beam cannot deal with the effect of turbulent atmospheric channels in free space optic (FSO) system, so we have proposed a novel hybrid WDM/multiple-beam system which can reduce the effects of tropical rain weather condition and provide a significant enhancement in the link range, scalability and received optical power. The result indicates that the SNR and FSO link ranges are improved by 20 dB and 3 km, respectively, by using the proposed technique in contrast to previous techniques.
