1. An optical signal dropper comprising:

  • a plurality of drop wavelength selection/input units, each having a first output port and a second output port, for outputting received input wavelength-specific optical signals from the output ports; and

    a drop output unit for outputting wavelength-specific optical signals output from the first output ports of the drop wavelength selection/input units, to respective different optical paths;

    wherein said drop wavelength selection/input units correspond respectively to a plurality of routes for transmitting wavelength-multiplexed optical signals, and each of said drop wavelength selection/input units receives a wavelength-specific optical signal included in the wavelength-multiplexed optical signal transmitted through a corresponding route and wavelength-specific optical signals output from the second output ports of other drop wavelength selection/input units, as the input wavelength-specific optical signals, and outputs each of the wavelength-specific optical signals from either said first output port or said second output port depending on the wavelength of the wavelength-specific optical signal.
