Description

低烟无卤阻燃低摩擦蝶形引入光缆 技术领域
本实用新型低烟无卤阻燃低摩擦蝶形引入光缆涉及的是两款结构、颜色多样的蝶形引入光缆，其具备普通蝶形引入光缆难以匹及的优异表面摩擦性能，并通过使用特殊增强吊线，达到其与护套之间几乎无法发生滑移、施工时不会发生光缆扭结的目的，在保证其优良施工性能的同时，还兼顾到端面阻水，是国内外人口密集地区入户布线首选产品。
背景技术
随着人们的生产生活对于信息的消费需求空前高涨，光纤通信技术在各个领域得到大范围的应用，以及光接入成本的不断下降，铜缆价格和铜线接入往运维成本攀升，大小运营商网络正在高速向着以宽带为特征的网络转型。随着越来越多高带宽业务的出现，FTTH/FTTB(光纤入户、光纤入大楼)已经成为诸多运营商的首选。随着信息化的深入，带来对接入光缆逐渐递增的极大需求。
在FTTH建设中最常见使用的就是蝶形引入光缆，多年以来，凭借着其优良的施工分离性能以及小巧的尺寸而成为国内外众多电信运营商最为青睐的接入光缆之一，同时，在诸多发展中国家，蝶形引入光缆也正逐步成为光纤接入网最后一段的焦点产品。
在进行入户敷设时，随着施工环境越来越多的局限、施工效率的提升，传统的蝶形引入光缆在使用中逐渐曝露出许多缺陷，尤其体现在旧城区通信线路改造工程中，传统蝶形引入光缆无法顺利穿过敷设有多根光/电缆的地下/空中管道，此前，有国内供应商开发出基于低摩擦PE护套材料的小尺寸低摩擦室内蝶形引入光缆，该种光缆可以在一定程度上增加其管道穿过率，并减小一端牵引力，但是，由于PE材料强度远远大于LSZH(低烟无卤阻燃料)，导致作为蝶形引入光缆本身一大亮点的简易开剥 性能丧失，分离力由不到10N增大到20N左右，甚至需要借助工具才能保证在开剥的时候不至于因为力值过大而引起剥离方向偏离和加强件裸露，此外，PE材料制成的蝶形引入光缆(甚至号称阻燃PE的材料)结构均无法通过IEC60332-1-2(国际电工委员会)规定的单根垂直燃烧试验，对于室内光缆而言，阻燃性能是考量其是否适宜在室内使用的重要标准之一。
蝶形引入光缆的表面低摩擦性能可以通过多根同类型光缆之间直接接触表面的滑动摩擦试验来验证，大量材料试验表明，本实用新型涉及的多款低烟无卤阻燃低摩擦蝶形引入光缆可以将多根该类型蝶形引入光缆之间的直接接触表面摩擦系数有效降低至0.25以下，而传统蝶形引入光缆之间的直接接触表面摩擦系数高达0.4以上。
另外，室外架空型蝶形引入光缆通常使用的黑色系也越来越影响城市住房内外部美观，本实用新型涉及的室外型低烟无卤阻燃低摩擦蝶形引入光缆在不影响表面摩擦性能和材料低烟无卤阻燃性能的前提下设计灰色和黑色两种可供用户选择。
发明内容
本实用新型目的是针对上述普通蝶形引入光缆在施工和使用时的不足之处，提供一种低烟无卤阻燃低摩擦蝶形引入光缆，可制作成室内、室外蝶形引入光缆，并在保证其低摩擦系数、阻燃等特性的前提下涉及三种颜色(室内白色，室外灰色/黑色)，本实用新型中的接入光缆具备摩擦系数极小、低烟无卤阻燃无毒、燃烧时发烟量小等一系列结构和材料优势；并且保留传统蝶形引入光缆易施工剥离的特性；通过使用特殊钢丝用作悬吊线，有效避免在施工放线过程中由于光缆扭结、打卷等造成吊线以下的缆体过于曲挠而折断光纤。
低烟无卤阻燃低摩擦蝶形引入光缆是采取以下技术方案实现：
低烟无卤阻燃低摩擦蝶形引入光缆是由外护套、着色光纤、加强件组 成，着色光纤两侧设置有加强件，着色光纤和加强件封装在外护套内，外护套设置为长腰形。外护套设置有圆弧面，在工程建设中入户、室内敷设时可以减少摩擦力。
在外护套一端设置有增强吊线，可以作室外型低烟无卤阻燃低摩擦蝶形引入光缆。室内型低烟无卤阻燃低摩擦蝶形引入光缆可以不设置有增强吊线。
所述的外护套采用低摩擦型热塑性低烟无卤聚烯烃阻燃护套料。
低烟无卤阻燃低摩擦蝶形引入光缆的制作方法简介如下：(室内型无增强吊线)
将增强吊线(钢丝)在专用放线架上安装好，设置好放线张力并牵引至分线模出口待用；将两根光缆加强件(可以为金属钢丝，或非金属FRP)在放线架上安装好，设置好加强件放线张力，沿加强件导轮牵引至分线模出口固定待用；将着色光纤按要求在光纤放线架上安装好，并设置好光纤放线张力，沿光纤放线导轮将其牵引至分线模出口，固定好待用；选择合适的蝶形引入光缆模具装配好；将增强吊线与两根加强件合并在一起穿过分线模，经过烘箱，穿过模具，并打开挤塑机进行挤塑；将光缆护套缓慢牵引并绕到轮式牵引设备上；将着色光纤经过分线模和烘箱，导入模芯；打开烘箱设置好温度；调节模套位置和挤塑大小，使得光缆内部加强芯、光纤可以分布均匀、不偏芯，光纤松紧度(要求在50cm长度光缆上开剥20cm护套，不使用任何工具徒手拉不出光纤)、光缆外径符合要求(室内型外径要求为1.6*2.0±0.1mm，室外型外径要求为2.0*5.3±0.2mm)；将符合工艺要求的光缆绕上储线轮，并拉至收线架处上盘收线。
低烟无卤阻燃低摩擦蝶形引入光缆有益效果：
·表面摩擦系数小，非常利于各种管道引入敷设时减小阻力，提高施工效率；
·材料无卤、低烟、无毒，并且阻燃性能优异，适用于各项FTTH室内接入工程；
·室外型低烟无卤阻燃低摩擦蝶形引入光缆可以有效防止施工过程中由于放线方式不当导致缆体与吊线扭结，进而引起的衰减增大、插入损耗增大甚至断纤；
·室外型低烟无卤阻燃低摩擦蝶形引入光缆端面阻水性能和抗UV性能优异，十分适宜室外接入场合；
·完美兼容传统蝶形引入光缆快速连接器，方便快捷；
本实用新型涉及两种结构(室内/室外)的低烟无卤阻燃低摩擦蝶形引入光缆，在开辟低摩擦性能的同时，保留了传统蝶形引入光缆结构简单、施工开剥简易、低烟无卤阻燃等优势，特别适用于FTTH工程建设中入户、室内敷设，节省施工时间，降低入户成本。
附图说明
以下将结合附图对本实用新型作进一步说明：
图1室外型低烟无卤阻燃低摩擦蝶形引入光缆示意图。
图2室内型低烟无卤阻燃低摩擦蝶形引入光缆示意图。
具体实施方式
下面结合附图对本实用新型做进一步描述，本专利的保护范围不局限于以下所述。
参照附图1～2，低烟无卤阻燃低摩擦蝶形引入光缆是由外护套1、着色光纤2、加强件3组成，着色光纤2两侧设置有加强件3，着色光纤2和加强件3封装在外护套1内，外护套1设置为长腰形。外护套1设置有圆弧面，在工程建设中入户、室内敷设时可以减少摩擦力。
在外护套1一端设置有增强吊线4，可以作室外型低烟无卤阻燃低摩擦蝶形引入光缆。室内型低烟无卤阻燃低摩擦蝶形引入光缆可以不设置有增强吊线4。
室外型低烟无卤阻燃低摩擦蝶形引入光缆由外护套1、着色光纤2、加强件3以及增强吊线4(钢丝)组成，而室内型低烟无卤阻燃低摩擦蝶形引入光缆由外护套1、着色光纤2和加强件3组成，与室外型相比较没有增强悬吊线。
所述的外护套1采用低摩擦型热塑性低烟无卤聚烯烃阻燃护套料。
所述的着色光纤2为1～12芯。
所述的低烟无卤阻燃低摩擦蝶形引入光缆，多根该型光缆之间直接接触表面摩擦系数达到0.25以下，在此前提之下保证光缆本身的阻燃特性满足IEC(国际电工标准)要求的单根垂直燃烧、燃烧低烟密度满足IEC要求的烟密度。IEC所述的低烟无卤阻燃低摩擦蝶形引入光缆，在满足低摩擦、阻燃、烟密度前提下，有包含灰色、黑色、白色在内的三种颜色室内/室外型光缆可以提供。
所述的低烟无卤阻燃低摩擦蝶形引入光缆，对于室外型低烟无卤阻燃低摩擦蝶形引入光缆，采用增强吊线钢丝达到其与护套之间紧密粘结的目的，并且整体光缆端面阻水，满足IEC要求的渗水试验。
所述的低烟无卤阻燃低摩擦蝶形引入光缆，无论室内还是室外型低烟 无卤阻燃低摩擦蝶形引入光缆结构均可以生产1～12芯光缆，其整体光缆尺寸相应增大。
对于室外型低烟无卤阻燃低摩擦蝶形引入光缆，增强吊线4采用钢丝，在这种钢丝表面挤塑护套时可以达到护套与钢丝紧密粘结的效果，与传统室外型蝶形引入光缆相比，增强吊线钢丝与护套之间根本无法发生滑移，有效避免了在施工放线时由于操作不当引起的缆体部分与吊线部分扭结，进而导致光纤衰耗增大、接头损耗增大，严重的甚至引起断纤的问题。
对于室外型和室内型低烟无卤阻燃低摩擦蝶形引入光缆，加强件3一般可以选择金属型(钢丝)，选择该种加强件一般考虑的是光缆(室外型则是对于缆体部分)在弯曲布线环境恶劣条件下拉伸强度高、无法折断，对光纤保护能力强；当选择非金属型加强件(FRP类)时，一般考虑的是光缆在室内一般环境下弯曲布线时柔软度高、弯曲后回弹性好。
对于室外型和室内型低烟无卤阻燃低摩擦蝶形引入光缆，着色光纤2一般可以为1芯～12芯，相应的整体光缆尺寸也会增大，对于FTTH布线光缆而言，由于考虑到多弯曲场合，所以一般选用的是弯曲不敏感类单模光纤。
对于室外型和室内型低烟无卤阻燃低摩擦蝶形引入光缆，外护套1是影响光缆整体低摩擦性能的关键项目，大量试验论证表明，同一种护套材料改变颜色后表面摩擦系数会发生显著变化，护套材料的表面摩擦性能与其阻燃性能很难以同时保证。经过为期近1年时间研发，目前已经开发出了灰色、黑色和白色三种颜色护套材料，并且通过大量的试验论证。
低烟无卤阻燃低摩擦蝶形引入光缆制作方法如下：(室内型无增强吊线)
将增强吊线(钢丝)在专用放线架上安装好，设置好放线张力并牵引至分线模出口待用；将两根光缆加强件(可以为金属钢丝，或非金属FRP)在放线架上安装好，设置好加强件放线张力，沿加强件导轮牵引至分线模出口固定待用；将着色光纤按要求在光纤放线架上安装好，并设置好光纤放线张力，沿光纤放线导轮将其牵引至分线模出口，固定好待用；选择合适的蝶形引入光缆模具装配好；将增强吊线、两根加强件和着色光纤穿过分线模，经过烘箱，穿过模具，并打开挤塑机进行挤塑；将光缆缓慢牵引并绕到轮式牵引设备上；打开烘箱设置好温度；调节模套位置和挤塑大小，使得光缆内部加强芯、光纤可以分布均匀、不偏芯，光纤松紧度(要求在50cm长度光缆上开剥20cm护套，不使用任何工具徒手拉不出光纤)、光缆外径符合要求(室内型外径要求为1.6*2.0±0.1mm，室外型外径要求为2.0*5.3±0.2mm)；将符合工艺要求的光缆绕上储线轮，并拉至收线架处上盘收线。
