摘要

自由空间光通信（FSOC）为现代网络提供了安全、高速的连接，但极易受到恶劣天气引起的衰减的影响。本研究利用涟川SOC示范研究中心的先进设施，评估了受控强降雨和浓雾下的全双工移动FSOC系统。实验结果证实，在35毫米/小时的降雨量和10米的能见度下，数据传输稳定在2.3 gb /s，显示了系统的弹性。与现有天气衰减模式的对比分析揭示了其显著的局限性，特别是在极端条件下，突出了模式改进的必要性。这些发现为推进FSOC性能建模提供了有价值的见解，并支持FSOC在下一代通信基础设施（包括移动平台、智慧城市和灾难恢复网络）中的部署。

Measurement-Based Evaluation of a Mobile Free-Space Optical Communication System Under Controlled Severe Weather Conditions

Free-space optical communication (FSOC) provides secure, high-speed connectivity essential for modern networks, but is highly susceptible to severe weather-induced attenuation. This study evaluates a full-duplex mobile FSOC system under controlled heavy rainfall and thick fog using the advanced facilities at the Yeoncheon SOC Demonstration Research Center. Experimental results confirm stable 2.3-Gb/s data transmission at 35-mm/h rainfall and 10-m visibility, demonstrating system resilience. Comparative analysis with existing weather attenuation models reveals their significant limitations, especially under extreme conditions, highlighting the need for model refinement. These findings offer valuable insights for advancing FSOC performance modeling and support the deployment of FSOC in next-generation communication infrastructures, including mobile platforms, smart cities, and disaster recovery networks.
