摘　　要：本文首先分析了光纤SCM通信系统中存在的噪声,然后深入讨论了光检测器的散粒噪声及其与光器件工作参数的关系和对载噪比C/N的影响,结论可作为实际系统设计时的依据。This paper gives the analysis of the noise existing in the optical fiber subcarrier Multiplexing(SCM) communications system and in-depth discussion of the shot noise of optical detector, the relation between it and the work parameter of optical devices and the influence of it on the carrier noise ratio(C/N).The results may be regarded as the foundation of the reality system design.
