Abstract: PURPOSE: An optical branch/coupler using one arrayed waveguide grating is provided to accommodate N optical signal channels, and to suppress the influence of crosstalk. CONSTITUTION: An arrayed waveguide grating(10) branches a multiplexed optical signal inputted through an input optical fiber into N connected ports, and multiplexes the optical signal inputted from N connection ports and then outputs it to an output optical fiber. N optical passive devices are connected to the N connection ports one by one, and branch the multiplexed optical signal into at least two outputs. And N optical switches receive inputs from at least two of the plurality of optical passive devices, and transfer the input to a channel receiver by selective switching, and transfer the optical signal received from a channel transmitter to the optical passive device. A fold back path is formed with one of two inputs of the optical switch and an optical passive device connected to the same.
