Abstract

一种双护套微型气送光纤单元,包括光纤及其外护套,在光纤与外护套之间设有内护层,光纤与内护层之间设有硅油填充物。本实用新型可以在管道内气送较长的距离,满足敷设需要,而且光纤不易受损伤。

Description

双护套微型气送光纤单元
技术领域
本实用新型涉及一种通信光纤单元,尤其是用于气送敷设的光纤单元。
背景技术
现有用于接入网系统的室内场合或局域网之间、小区之间的室外场合的气送光纤单元,一般在光纤外包覆外护套。这种光纤单元在管道内气送敷设距离短,一般在500米以内,不能满足较长距离的气送敷设需要,其机械性能也较差。
发明内容
本实新型的目的是克服现有气送光纤单元的不足,提供一种双护套微型气送光纤单元,能够满足较长距离的气送敷设需要,其机械性能也得到增强。
本实用新型提供的一种双护套微型气送光纤单元,包括光纤及其外护套,在光纤与外护套之间设有内护层,光纤与内护层之间设有硅油填充物。
本实用新型的有益效果是,可以将光纤单元气送较长的距离,满足敷设需要,而且其机械性能也得到增强,光纤不易因侧压力和拉伸力的作用而受损伤。
附图说明
图1是本实用新型的横截面示意图。
在图1中,1、光纤,2、硅油填充物,3、内护层,4、外护套。
具体实施方式
参照图1,先在数根光纤1之间充入硅油填充物2,再包覆内护层3和外护套4,即制成本实用新型。
