| 摘 要： | 为了研究单模光纤对城域网和接入网以及FTTH的容量与性能的提升，使用大功率、窄线宽的高性能光纤激光器作为系统光源，分别测量了3种光纤到户用单模光纤的受激布里渊散射（SBS）阁值。从理论上分析了光纤SBS阂值估算公式及影响阂值的因素，理论估算值与实验测量值吻合很好。实验发现的一种G．652D光纤具有高达12mw的SBS阈值，对此进行了分析。

| Abstract: | In order to study the capacity and performance enhancement on the MAN, access network and FTTH by single mode optical fiber, a fiber laser with high-power and narrow bandwidth is used as a light source, for measurement of the stimulated Brillouin scattering threshold of three kinds of single-mode fibers used for FTTH. The experimental results are well agreed with the theoretical analysis. It is found that the threshold of a G. 652 fiber has a SBS threshold as high as 12 mW by experiment, and is analyzed in this paper. |
