Improved performance of hybrid optical communications system

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