摘　　要：本文针对我国通信行业标准《通信线路工程验收规范》(YD5121-2010)的规定,阐述了光纤色散指标对传输系统技术性能的影响,建议修改现行通信线路工程验收标准的有关规定,增加光纤色度色散指标验收测试项目,限定偏振模色散的验收测试条件,有利于进一步有效保证传输系统的质量,并便于工程中实际操作。Based on the analysis of national telecommunication standard《Acceptance Standard for Communication Cable Engineering（YD5121-2010）》,this paper introduces the influence of optical fiber cable metrics on traditional transmission technology and proposes suggestions for the current communication cable engineering acceptance standard.The proposed suggestion includes adding testing programs for optical fiber chromatic dispersion and limiting the testing acceptance requirements for po-larization mode dispersion.The proposal can enhance the quality of transmission system and facilitate the practical deployment.
