Abstract

本实用新型涉及一种1×n光开关,所述光开关包含有光缆(1)、透镜(2)和反射镜(3),所述光缆(1)内包含有n根光纤(n≥2),所述光缆(1)的出光端正对透镜(2)的一侧,所述透镜(2)的另一侧正对反射镜(3)。本实用新型1×n光开关,结构简单、体积小且成本低廉。

Description

1×n光开关
技术领域
本实用新型涉及一种光开关,属于光学技术领域。
背景技术
目前,随着人们对网络带宽的更好要求,光通讯被人们寄予厚望。在光通讯中,光开关作为基础元件,其直接关系到整个光通讯系统的通讯质量。常规的1×n光开关时在1×2光开关的基础上进行级联而成,因而当n较大时,其结构也相应的更为复杂,体积变大,成本也相对提高。
发明内容
本实用新型的目的在于克服上述不足,提供一种结构简单、体积小且成本低廉的1×n光开关。
本实用新型的目的是这样实现的:一种1×n光开关,所述光开关包含有光缆、透镜和反射镜,所述光缆内包含有n根光纤(n≥2),所述光缆的出光端正对透镜的一侧,所述透镜的另一侧正对反射镜。
与现有技术相比,本实用新型的有益效果是:
采用本实用新型光开关后,随着n的增大,只需增加光缆内的光纤数量即可,因而结构简单,体积和元器件也不会随着n的增大而大肆增加,从而节约了整个光开关的成本。
附图说明
图1为本实用新型1×n光开关的结构示意图。
图2为本实用新型光缆的横截面示意图(其中中间打阴影线的光纤为入射光纤)。
其中:
光缆1、透镜2、反射镜3。
具体实施方式
参见图1和图2,本实用新型涉及的一种1×n光开关,所述光开关包含有光缆1、透镜2和反射镜3,所述光缆1内包含有n根光纤,所述光缆1的出光端正对透镜2的一侧,所述透镜2的另一侧正对反射镜3(n≥2)。
本实用新型的工作原理为:入射光源经由光缆1内的某一光纤(中间打阴影部分的光纤)后进入透镜2,经透镜2后入射到反射镜3上,随后由反射镜3反射经透镜2后从光缆1内的另一根光纤出射。实际使用时,可在反射镜3的背面加装微机电系统,从而可以对反射镜3的角度进行调节,使得光线可以进入某一特定的选择好的光纤内出射。
