摘　　要：针对通信系统中逐步大量应用的低损耗、超低损耗光纤的现状,本文参考了行业内的相关技术资料,分析了低损耗、超低损耗光纤的相关特性,探讨了低损耗、超低损耗光纤的应用与发展前景,提出了光缆衰减链路值作为科学评价光缆衰减的参数,并列出了应用的实例及成本概算,最后结合现有标准的状况和生产实际提出了衰减指标的修改建议。In view of the present status of low loss and ultra-low loss fiber which been gradually applied to commnnication system, this paper reviews the characteristics of low loss andultra-low loss optical fiber, investigated their application and prospects. This paper explored and proposed link design value as an improved approach to assess attenuation. Actual application cases of low loss fiber and ultra-low loss fiber and associatedcost analysis have been presented. With the existing standards and actual data from mamffacturers, the paper puts forward file suggestions for modification of attenuation specification.
