Keywords:FSO, MIMO, DWDM, EDFA, BER, Q-Factor, OSNR
The present article aims to investigate and evaluate the performances of DWDM (or Dense Wavelength Division Multiplexed) system under MIMO-FSO (or multiple input multiple output-free space optical) channel. However, the proposed system is configured and simulated in the worst-case meteorological conditions, and we base here on the variation of the attenuation coefficient. In this article, the proposed system is devoted to 90 users, every user exploits 30 Gbps. So, the total capacity of system is 90x30 Gbps. In addition, the use of MIMO technique in FSO channel ensures us the stability of the proposed system in the worst-case meteorological conditions and especially when the system exploits a high throughput. To assess the acceptable performance levels of the proposed system, it is necessary to use the following criteria: the minimum bit error rate (or BER) performance, the maximum quality factor (or Q-Factor) and the optical signal to noise ratio (or OSNR) performance. Finally, the proposed system in this paper provides a promising solution for 5G networks as back-up optical link.
