摘要：

This paper successfully demonstrated simulated analysis and investigation of 100 multichannel DWDM-based FSO system having each channel data rate 10 GB/s separated by 100 GHz frequency spacing under adverse weather conditions such as haze, heavy rain and heavy dust fog. Apart from this, a comparison of two modulation formats RZ and NRZ has been performed to optimize the system performance under different climate conditions at diverse visibility ranges. The performances of the proposed work have been compared in terms of BER, Q-Factor, SNR, eye diagrams and received signal power on 193.1 THz. It has been observed that NRZ modulated system showed robust performance as compared to the RZ modulated system for transmitting 1 TB/s data rate over free space with acceptable values of BER ≥ e-22 & Q-Factor ≤ 9.6 dB. © 2023 Walter de Gruyter GmbH, Berlin/Boston.
