Description
技术领域
本发明属于光收发一体单纤双向器件技术领域,具体涉及一种可有效降低内部串扰的光收发一体单纤双向器件。
背景技术
目前,单纤双向通信技术在光通信领域已取得非常广泛的应用,作为单纤双向光通信的核心部件---光收发一体单纤双向器件也有着多种多样的设计方案,这类器件存在串扰大的缺点,发射端的杂散光、发射端光经过光纤端面陶瓷端面发射会进入探测器,形成串扰干扰探测器正常工作;市面上的产品通过光纤端面镀增透膜可解决光纤端面发射问题,通过陶瓷插芯倒角降低部分发射;但无法有效解决发射端杂散光进入探测器的问题、也无法有效解决陶瓷端面发射光进入探测器的问题。
发明内容
本发明的目的是为了解决以上现有技术的不足,提出了一种可有效降低内部串扰的光收发一体单纤双向器件,包括单纤双向壳体、滤波组件、激光发射器、接收探测器和光接口组件,所述的单纤双向壳体为矩形壳体,单纤双向壳体两侧分别设有激光发射器和光接口组件,单纤双向壳体底部设有凹陷开口,所述的接收探测器设在凹陷开口内,所述的滤波组件设在单纤双向壳体内部,滤波组件包括滤波管和滤波片,所述的滤波管为圆柱型管件,滤波管外侧设有透光口,所述的滤波片倾斜的设在滤波管内部,滤波片与透光口对齐。
更进一步的,滤波组件与激光发射器和光接口组件同圆心,滤波组件通过滤波管与激光发射器和光接口组件相连。
更进一步的,透光口大小与滤波片大小相等。
更进一步的,滤波管内壁设有吸光涂料。
有益效果:
通过在滤波片、激光发射组件和光接口组件之间增加滤波管,从而避免光收发一体单纤双向器件内部在发射光纤时,单纤双向壳体内壁会折射激光而减小激光的串扰。
附图说明
图1是一种可有效降低内部串扰的光收发一体单纤双向器件的剖面示意图;
图中:1、单纤双向壳体,2、接收探测器,3、滤波管,4、光接口组件,5、光纤,6、激光发射器,7、滤波片。
具体实施方式
为了加深对本发明的理解,下面将结合实施例和附图对本发明进一步详述,该实施例仅用于解释本发明,并不构成对本发明保护范围的限定。
实施示例:
一种可有效降低内部串扰的光收发一体单纤双向器件,包括单纤双向壳体、滤波组件、激光发射器、接收探测器和光接口组件,所述的单纤双向壳体为矩形壳体,单纤双向壳体两侧分别设有激光发射器和光接口组件,单纤双向壳体底部设有凹陷开口,所述的接收探测器设在凹陷开口内,所述的滤波组件设在单纤双向壳体内部,滤波组件包括滤波管和滤波片,所述的滤波管为圆柱型管件,滤波管外侧设有透光口,所述的滤波片倾斜的设在滤波管内部,滤波片与透光口对齐。
如图1所示;
将光纤5插入光接口组件4,将接收探测器2插入单纤双向壳体1底部的凹陷开口,启动单纤双向器件,激光发射器6启动,光纤5通过滤波片7折射至接收探测器2,同时通过滤波管3内的吸光涂料减少光在通过滤波片7时在单纤双向壳体1内的折射,从而增加单纤双向器材的串扰。
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
