    • An light input/output unit has at least three first ports, including a first input port for inputting light and a first output port for outputting light; at least three second ports, including a second input port for inputting light and a second output port for outputting light; and an alignment port for inputting and outputting alignment light. An optical axis of the input/output light of the first port and an optical axis of the input/output light of the second port differ from each other. The dispersive element changes the optical axes of input/output lights of the first and second ports by an angle corresponding to a wavelength. The light deflective element has a first part for directing the light from the first input port to the first output port and a second part for directing the light from the second input port to the second output port.
    • 光输入/输出单元具有至少三个第一端口,包括用于输入光的第一输入端口和用于输出光的第一输出端口; 至少三个第二端口,包括用于输入光的第二输入端口和用于输出光的第二输出端口; 以及用于输入和输出对准光的对准端口。 第一端口的输入/输出光的光轴和第二端口的输入/输出光的光轴彼此不同。 分散元件将第一和第二端口的输入/输出光的光轴改变对应于波长的角度。 光偏转元件具有用于将光从第一输入端口引导到第一输出端口的第一部分和用于将光从第二输入端口引导到第二输出端口的第二部分。
