【NO.】PMFWDM-R1480T1550-26Nv06
滤玻片型PMFWDM保偏光纤波分复用器(1480/1550nm)

波分复用器是能将两种或两种以上不同波长的光型号光耦合在一芯光纤中传输的器件,反之也能将在一芯光纤中的两种或两种以上不同波长的光信号在分别分离解复用。由图可见,两束不同的光由公共端(Common)输入,WDM器件会允许将其中一束特定波长的光透射过去,在透射端输出,而将剩余波长反射耦合至反射端输出,即光波分的过程。同理,WDM器件光路可逆。

介质膜滤波片采用薄膜干涉原理,使某些波长的光在薄膜上产生较强反射而不能透过薄膜,而其他波长的光则可以透过薄膜。为提升反射效率,介质膜滤波器片通常采用多层薄膜(一般为50-100层),通过多层介质膜的干涉使某一波长通过,其他波长反射。
