Description

一种用于室内布线的隐形带状光缆 技术领域
本发明涉及室内光缆领域，具体涉及一种用于室内布线的隐形带状光缆。
背景技术
随着光纤通信的飞速发展，光纤通信在极大地便利了人们的生活的同时，也使得用户对网络带宽的需求急剧增加，FTTH(fiber to the home，光纤到户)已成为必然。在FTTH的工程中，用户室内布线是最为复杂的环节，考虑的因素较多，既要保证线路安全，又要兼顾室内美观，同时还要施工便利。
目前室内布线主要采用蝶形和圆形引入光缆，蝶形和圆形引入光缆在室内布线时，均需要通过在墙体上打洞、并布置卡钉来固定。在墙体上打洞和布置卡钉均不仅破坏了室内装修，而且操作过程比较复杂；与此同时，由于蝶形和圆形引入光缆的尺寸较大，不同尺寸光缆的颜色对比鲜明，因此尺寸较大、颜色对比鲜明的光缆布放在用户墙面上显得很不协调，不够美观，降低了用户的满意度，难以满足现阶段光纤到户工程室内布线的要求
发明内容
针对现有技术中存在的缺陷，本发明解决的技术问题为：在简化带状光缆走线过程的同时，不会破坏室内装修、并保证室内的美观。本发明能够在满足用户极速上网的同时，不会破坏精心装修的家居，特别适用于室内布线、工业控制和文物保护等环境要求较高的领域。
为达到以上目的，本发明提供的用于室内布线的隐形带状光缆，该隐形带状光缆包括2～10根隐形光纤单元，每根隐形光纤单元的外径均为500～1500μm；每根隐形光纤单元的外部均覆有保护层，每根隐形光纤单元与其外部的保护层一次挤塑成型；保护层的材质为聚氯乙烯、低烟无卤阻燃聚烯烃或低烟无卤阻燃热塑性聚氨酯弹性体；
所述隐形光纤单元包括涂覆光纤、以及包覆于涂覆光纤外部的隐形被覆层；隐形被覆层的材质包括尼龙和聚氯乙烯。
在上述技术方案的基础上，所述涂覆光纤采用技术指标为G.657A1、G.657A2或G.657B3的单模光纤。
在上述技术方案的基础上，所述涂覆光纤采用涂覆有特殊树脂的光纤。
在上述技术方案的基础上，所述隐形光纤单元的数量为5根，每根隐形光纤单元的外径均为800～1200μm。
在上述技术方案的基础上，所述每根隐形光纤单元的外径均为900μm。
在上述技术方案的基础上，所有隐形光纤单元外部的保护层的整体横截面呈连续的横向8字形。
与现有技术相比，本发明的优点在于：
(1)本发明的隐形光纤单元的外径为500～1500μm，与现有技术中的蝶形和圆形引入光缆相比，隐形光纤单元的外径较小，重量较轻。因此，本发明的隐形带状光缆布线时，可直接粘覆于墙体走线，不需要在墙体上打洞、并布置卡钉来固定，不仅不会破坏室内装修，而且操作过程比较简单。
与此同时，本发明的所有隐形光纤单元外部的保护层的整体形成连续的横向8字形的带状结构，连续8字形的带状结构使得剥离保护 层和隐形光纤单元时比较简单，简化了隐形光纤单元分别布线到不同的用户室内的走线过程。
(2)本发明的保护层和隐形被覆层的均采用透明材质，透明材质的带状光缆能够与室内装饰融为一体，不会影响室内的美观。
综(1)和(2)所述，本发明的带状光缆的尺寸小、重量轻、光纤弯曲不敏感、易安装，易与环境结合为一体，不仅不会影响室内美观，而且能够同时为多个用户布线。因此，本发明能够在满足用户极速上网的同时，不会破坏精心装修的家居，特别适用于室内布线、工业控制和文物保护等环境要求较高的领域。

图1为本发明实施例中用于室内布线的隐形带状光缆的横截面示意图。
图中：1-保护层，2-隐形光纤单元，2a-隐形被覆层，2b-涂覆光纤。
具体实施方式
以下结合附图及实施例对本发明作进一步详细说明。
参见图1所示，本发明实施例中的用于室内布线的隐形带状光缆，采用平拖方式生产，该隐形带状光缆包括2～10根隐形光纤单元2，每根隐形光纤单元2的外径均为500～1500μm。每根隐形光纤单元2的外部均覆有保护层1，保护层1的材质可以为聚氯乙烯、低烟无卤阻燃聚烯烃或低烟无卤阻燃热塑性聚氨酯弹性体；每根隐形光纤单元2与其外部的保护层1一次挤塑成型，所有隐形光纤单元2外部的保护层1的整体横截面呈连续的横向8字形(即形成连续8字形的带状结构)。
隐形光纤单元2包括涂覆光纤2b、以及包覆于涂覆光纤2b外部的隐形被覆层2a；涂覆光纤2b采用技术指标为G.657A1、G.657A2或G.657B3的单模光纤，涂覆光纤2b还可以采用涂覆有特殊树脂的光纤；隐形被覆层2a的材质主要包括尼龙和聚氯乙烯等。
