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。

粗波分复用器CWDM模块采用TFF(薄膜滤波器) 技术,由符合ITU-T G.694.2 标准,在1270-1610 nm范围内每间隔20nm一个通道。它可以通过一芯光纤承载2-18个CWDM波长,每个波长不会影响另一个波长,因此信号不会干扰。每个通道通常对数据的速度和类型是透明的,因此任何组合的传输业务类型都可以通过单根光纤或一对光纤同时传输。
