Abstract
Disclosed is a wavelength division multiplexing optical switching system, which is connected with a plurality of nodes of an optical network and supports communication between the nodes. The optical switching system includes a wavelength division demultiplexing unit which demultiplexes optical signals received from each of the plurality of nodes and outputs them as channels with different wavelengths. A routing unit which classifies the channels in accordance with destinations thereof. A fixed wavelength converting unit which converts the classified channels into channels of a single wavelength, the single wavelength being allocated in accordance with corresponding starting places. A wavelength division multiplexing unit which collects the wavelength-converted channels in accordance with destinations and then outputs them as multiplexed optical signals.
