The role of optical fiber branching device and working principle

:

(1) to a primary light source the light into 1 - via the shunt N of the light path;

1 - (2) is N of the optical path through the bypass to synthesize into a bunch of recycling the main light.

工作原理:

在单模光纤传导光信号的时候光的能量并不完全是集中在纤芯中传播,有少量是通过靠近纤芯的包层中传播的也就是说在两根光纤的纤芯足够靠近的话在一根光纤中传输的光的模场就可以进入另外一根光纤光信号在两根光纤中得到重新的分配
