前言我国光纤通信科技工作者常讨论松套光纤和紧套光纤的优缺点,国际上许多文献将此问题归结为光缆的松结构和紧结构问题。因这属于光缆的结构设计范畴,而且光缆中的光纤不一定采用套管或者不一定每一根光纤有一根套管。本文是根据一些国际资料,对此两种结构光纤进行一些综合评述,并建议我国应加速进行松结构光缆的研制。
Preface China’s optical fiber communication technology workers often discuss the advantages and disadvantages of loose sleeve optical fiber and tight sleeve optical fiber, many international literature attributed this problem to the loose structure and tight structure of the optical fiber. Because this belongs to the category of fiber optic cable design, and fiber optic cable does not necessarily use the casing or not necessarily a fiber each casing. This article is based on a number of international information, some of the two kinds of structural fiber for a comprehensive review, and suggested that China should speed up the development of loose structure of the optical cable.
