Abstract
Frees Space Optical (FSO) system employs empty space to transfer information between the transmitter and receiver using light. The single-beam Single Input Single Output (SISO) technology is well known for being subject to air attenuation induced by weather conditions, which decreases the performance link range and data quality. The proposed system in this research is a combination of DWDM and MIMO approaches to address this issue. The research is based on Optisystem simulations with various weather reduction in many of FSO systems: the FSO-DWDM-SISO (FDS) scheme and the suggested FSO-Hybrid-DWDM-MIMO method (FHDM). FHDM technology has considerably enhanced connection distance, received power, scalability, and data speed. At a data rate of 500 Mb/s, an evaluation is made between the suggested method and the FDS with respect to quality-factor during varied weather reduction using different numbers of optical transmission beams. The results show that the FHDM system improves connection distance, received optical power, minimum bit error rate (BER), and highest quality-factor significantly during various weather conditions.
