Spectrum slicing WDM for FSO communication systems under the heavy rain weather

Abstract In the paper, the spectrum sliced wavelength division multiplexed (SS-WDM) is proposed for Free Space Optic (FSO) communication in the heavy rain weather of Changsha, China. The study seeks to investigate the possibility of communication links up to 3 km with 1.56 Gb/s data rate on the wavelength of 1550 nm. A WDM-Demux is used to operate as slicing system. The SS-WDM-FSO system has been realized and investigated for 4 channels with data rate up to 1.56 Gb/s using a continue wave (CW) laser source with and without SS technique. The simulation results show that, using the SS-WDM technique, a data rate of 1.56 Gb/s is achieved over a transmission distance of 2.5 km with the bit error ratio of nearly 9.816×10 –11 and the power of 0 dBm. Meanwhile transmitting over FSO channel using WDM without spectrum slicing, the sampled data rate is achieved over a transmission distance of 2.5 km with the BER of 10 −3 on power supply of 10 dBm. In addition, the proposed SS-WDM scheme can improve the FSO communication system performance compared to WDM-FSO scheme. Also, its adaptive and scalable network architecture support high bandwidth and wide coverage area over the heavy rain weather, without power penalty.
