Optical fiber short base pin and optical module employing same

光纤短插针及使用其的光模块

Abstract

本实用新型提供光纤短插针及使用其的光模块,其能够降低光损失且可实现小型化。光纤短插针具备:套圈(2),其在轴中心形成有可插入光纤的贯通孔(2a)的套圈(1)的局部侧面设置有在贯通孔(2a)的中途与贯通孔(2a)连通并使贯通孔(2a)露出到外部的切口部(2b);光纤(3、5),其从贯通孔(2a)的各端部插入,前端具有斜研磨面;光学滤波器,其形成于光纤(5)的斜研磨面,将波长复用的光信号进行分离,使设有光学滤波器的光纤(5)及光纤(3)的各前端在贯通孔(2a)露出的部分的大致中央以包括光学滤波器各斜研磨面彼此成同一平面的方式抵接,且以将通过光学滤波器分离的光信号至少导向切口部(2g)的方式将各光纤(3、5)固定于贯通孔(2a)。
The utility model provides an optical fiber short base pin and an optical module employing the fiber short base pin. The optical fiber short base pin can reduce light loss and realize miniaturization. The optical fiber short base pin comprises a ferrule (2), optical fibers (3) and (5) and an optical filter; a through hole (2a) for allowing optical fibers to be inserted is formed in the center of the shaft of the ferrule (2), and a notch part (2b) which is communicated with the through hole (2a) midway and enables the through hole (2a) to be exposed outside is arranged on the local side surface of the ferrule (2); the optical fibers (3) and (5) are inserted in from each end of the through hole (2a), and an inclined grinding surface is arranged at the front end of each optical fiber; and the optical filter is formed on the inclined grinding surface of the optical fiber (5), the wavelength multiplexing optical signals are separated, so that the respective front ends of the optical fibers (3) and (5) which are provided with the optical fibers respectively are propped in the approximate center of the exposed part of the through hole (2a) in the way that all the inclined grinding surfaces of the optical fiber constitute the same plane one another, and the optical fibers (3) and (5) are fixed in the through hole (2a) by at least guiding the optical signals separated through the optical fiber into the notch part (2g).
