Description

一种高性能光纤快速成端组件
技术领域
本发明涉及一种高性能光纤快速成端组件，具体涉及各种型号预埋式光纤快速成端组件。
背景技术
目前，随着光纤通信技术的飞速发展，PON接入技术已成为全球FTTH（光纤到户）全面推广的最主要解决方案。然而，在这最后的一公里接入安装，如何做到入户成本低、安装方便、快捷高效，同时又要具备好的光学性能、高的可靠性能是十分关键的。
对于FTTH（光纤到户）的接入安装，传统的光纤熔接技术，由于其成本高、安装时受场地的限制，安装人员需要专业培训等原因而无法得到大面积的推广。光纤快速成端组件以其安装方便、快速、高效等优势，已成为目前FTTH接入的最优选择方案。
在现有的快速成端组件中常见的有直通式（也称直插式或干式）和预埋式。直通式快速成端组件由于现有技术的限制，性能指标不够稳定，无法满足光纤到户的连接需求。一般的预埋式快速成端组件，是在陶瓷插芯内孔中预埋一根光纤，一端与陶瓷插芯经研磨抛光后形成与正常连接器对接的端头，另一端则露出一定长度并保证端面平整，然后将露出端光纤安装在一个V型槽中，V型槽配备相应的光纤压贴块用来固定外入光纤和预埋光纤的对接，对接时在V型槽中提前预置匹配凝胶，同时还附带光缆锁紧装置。在现场施工时，将光纤切割后通过V型槽和预埋光纤对接实现快速连接。但是，该方案存在很多问题，如：1）由于预埋光纤一端外露在插芯外，整个工艺流程中容易折断，造成产品的报废；2）V型槽制作的精度不高，对接光纤无法实现同轴对接导致插损偏大；3）V型槽与插芯成独立配件，一般经过胶合固定，在温度变化时，产品的可靠性得不到保证；4）产品材料长时间服役容易老化、变形；5）现场组装一次成功率低，约10%需进行二次装配。
发明内容
本发明的目的是提供一种高性能光纤快速成端组件，利用陶瓷插芯的高精度内孔对接取代现有的塑料V型槽，它不仅可以做到安装方便、快速、高效且入户成本低，同时又具备好的光学性能和高的可靠性。本发明完全解决了目前快速成端组件存在的各种失效或不良问题。
本发明的技术解决方案是：一种高性能光纤快速成端组件，包括插芯体及位于插芯体内的内孔，所述插芯体削除部分柱体后露出内孔形成一对接平台,预埋光纤与对接光纤在所述对接平台的内孔处实现对接，对接平台上设有一用于压紧两光纤对接点的压紧结构。
本方案中，预埋光纤与对接光纤在内孔中实现对接，避免预埋光纤外露而造成易折断的缺陷；另外，对接平台与插芯体为一体成型材料，制作工艺更为简单，产品的可靠性更佳；利用压紧结构及内孔自身的管束作用， 解决了现有技术光纤对接时容易出现的错位或倾角问题导致的插损偏大。
进一步地，所述压紧结构包括用于抵压光纤对接点的压块及用于固定压块的紧箍套。
进一步地，所述压块设有一槽，用于预置保护光纤匹配凝胶 ，匹配凝胶在长时间使用时挥发或流失，预置匹配凝胶可以随时补充，同时多次穿入光纤时保证了对接面有足够的匹配凝胶。
所述插芯体及压块的接入端上均设有光纤导入孔。具体地，所述插芯体一端为常规活动连接器端头，另一端设有V型导入孔，方便光纤从其导入穿入内孔中。
本发明使用陶瓷插芯内孔对接点代替现有的V槽内对接的优点在于：
一、高性能光纤快速成端组件，具备好的光学性能和高的可靠性。
二、在整个制作流程中，预埋的光纤保护在插芯体的内部不易被损伤，保证了其在工厂加工的质量和成本。而目前的光纤快速连接器都是预埋光纤外露，在组装时容易折断，同时会出现光纤端面受损或粘有赃物，导致对接失效。
三、两光纤对接点是高精度的陶瓷插芯内孔形成的C型槽，插芯内孔容易做到1um以内的公差精度，使两光纤对接后损耗小于0.1dB。
四、光纤对接处的插芯内孔在外力挤压下不变形，不失效。而使用有机材料的V型槽在外力挤压或者自身携带弹簧的挤压下，容易变形失效。
五、在压块凹槽内预置足够的匹配凝胶，多次对接或长时间服役后可以补充匹配凝胶。
六、现场组装一次成功率高，性能优越。

具体实施方式
如图1、图2及图3所示，本发明公开一种高性能光纤快速成端组件，包括插芯体1及 位于插芯体1内的内孔，其中，所述插芯体1削除部分柱体后露出内孔形成一对接平台9,预埋光纤2与对接光纤8在所述对接平台9的内孔处实现对接，对接平台9上设有一用于压紧两光纤对接点7的压紧结构。具体地，所述压紧结构包括用于抵压光纤对接点的压块4及用于固定压块4的紧箍套3。
本发明所加工的插芯体，其可由挤出或注射成型工艺制成坯体后经过打磨抛光并通过精密磨床进行修磨加工而成，也可以利用磨床切刀或腐蚀工艺等完成形状修改。插芯体内孔直径控制在1um的误差内。该尺寸范围在工艺上容易实现，内孔直径相对光纤直径 大1um，可以容易实现穿入对接光纤，同时达到1um以内的同轴对接，确保光纤对接插损小于0.1dB。
在插芯体1内孔接入一段预埋光纤2，预埋光纤2一端和插芯体1端面经工厂打磨抛光后和正常的连接头对接，另一端预埋之前确保端面平整清洁，并将对接端面定位在对接平台9中。
所述压块4设有一槽5，用于预置保护光纤匹配凝胶6。在预埋光纤2端面处预置足量的光纤匹配凝胶6。当对接光纤8进入对接平台9和预埋光纤2对接后，在紧箍套3的作用下压块4和插芯体1的对接平台9闭合，对接光纤8在对接平台9的内孔中实现同轴对接。
