摘　　要：介绍了一种单模超低损耗G.652光纤,其与普通G.652D光纤的实验对比表明,该光纤在损耗、受激布里渊散射阈值、偏振模色散等方面具有较大优势,而其他指标则处于相当水平。分析表明,在一定条件下该光纤也具有相对的经济性优势。在"十二五"智能电网大发展时期,这种光纤无疑将成为延长配套光纤通信传输距离的另一有效解决方案。This paper introduces a single-mode ultra-low loss optical fiber, which complies with the industry＇s standard ITU-T Recommendation G.652. The experimental comparison between this fiber and G.652D fiber shows that it has the advantages in loss, stimulated brillouin scattering threshold, and polarization mode dispersion, while other indicators at a considerable level. In addition, the article analyses that under certain conditions, this fiber also has a relative economic advantage. During the development of smart grid in the ＂Twelfth Five-Year Plan＂ period, this fiber will undoubtedly be another effective solution to extend transmission distance.
