Abstract

一种接入网用墙内直埋光缆，包括缆芯及外护套，缆芯内具有由光纤、纤膏、光纤套管共同构成的光纤单元以及中心加强件、阻水纱、填充绳，在缆芯与外护套之间设有皱纹钢带铠装层，在皱纹钢带铠装层与外护套之间设有撕裂绳。本实用新型光缆弯曲半径大、体积小，可在楼宇建设的过程中或楼宇建成之后直埋敷设在墙体内部，不会影响楼宇的整体美观效果，而且在敷设过程中光缆也不容易受损伤，方便光缆的敷设施工。

Description

接入网用墙内直埋光缆
技术领域
本实用新型涉及一种通信光缆，尤其是接入网用的用户引入光缆。
背景技术
现有接入网用的用户引入光缆普遍使用在已建成楼宇，由于这类光缆弯曲半径小、体积大，整个楼宇的布线多采用明线，影响整体的美观效果，而且在敷设过程中光缆容易受损伤，影响光缆的敷设施工。
发明内容
为了克服现有接入网用的用户引入光缆的不足，本实用新型提供一种接入网用墙内直埋光缆，可在楼宇建设的过程中或楼宇建成之后直埋敷设在墙体内部。这样，不会影响楼宇的整体美观效果，而且在敷设过程中光缆也不容易受损伤，方便光缆的敷设施工。
本实用新型提供的一种接入网用墙内直埋光缆，包括缆芯及外护套，缆芯内具有由光纤、纤膏、光纤套管共同构成的光纤单元以及中心加强件、阻水纱、填充绳，在缆芯与外护套之间设有皱纹钢带铠装层，在皱纹钢带铠装层与外护套之间设有撕裂绳。
本实用新型的有益效果是：光缆弯曲半径大、体积小，可在楼宇建设的过程中或楼宇建成之后直埋敷设在墙体内部，不会影响楼宇的整体美观效果，而且在敷设过程中光缆也不容易受损伤，方便光缆的敷设施工。
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、光纤套管，3、纤膏，4、阻水纱，5、中心加强件，6、填充绳，7、外护套，8、皱纹钢带铠装层，9、撕裂绳，10、缆芯，11、光纤单元。
具体实施方式
参照图1，在光纤套管2内设置光纤1和纤膏3制成光纤单元11，将中心加强件5、阻水纱4、填充绳6与光纤单元11一起绞合制成缆芯10，在缆芯10外包覆皱纹钢带铠装层8并设置撕裂绳9，再包覆外护套7，即制成本实用新型。
