摘　　要：FSO以其巨大的传输带宽而倍受瞩目,但是需要对FSO的实用性和可靠性进行深入的研究。论文主要讨论雨和雾对光信号传输的衰减,给出了理论模型,并对模型进行了仿真,得到一些有益的结论。论文最后把两种衰减模型进行对比分析,得出了两个模型的相似性。论文分析结果给FSO系统设计提供了理论支持和技术保障。FSO is well known for its enormous transmission bandwidth, but we need go deep into studying the availability and reliability of FSO. The paper mainly discuss the transmission attenuation of light signals through rain and fog, propose the theory model, simulate the model and get some beneficial conclusions. Finally the paper oompare and analyze the two attenuation models and achieve the oomparability of the two models. The analysis results provide the theory and technology support for FSO system design.
