摘　　要：气吹微型光缆(微缆)的结构极度微型,使其低温特性面临较大挑战。通过完善传统光缆的设计方法和思路,并借助光缆的综合线膨胀系数对气吹微缆的低温极限值进行了预估,以判断其能否在指定的低温环境下正常工作。同时,给出改善气吹微缆低温极限值的方法。The extremely micro of air-blown microcable makes the low-temperature performance face greater challenges.By improving the design methods and ideas of the traditional fiber optic cable and using integrated linear expansion coefficient,the low-temperature limit of air-blown microcable is estimated.The result is used to judge whether the air-blown microcable can work in the given low-temperature.In addition,the method to improve the lowtemperature limit of the air-blown microcable is pointed out.

关 键 词：气吹微缆 光缆设计 线膨胀系数 低温极限值
