ABSTRACT:
An optical communication network system that communicates by wavelength division multiplexing. The optical network system includes a plurality of communication devices for communicating with one another. At least one of the communication devices is connected as a connection communication device to each of plural multi/demultiplexing devices. A plurality of optical signals are assigned to as assigned optical signals to the communication devices, respectively. The optical signals have wavelengths different from one another, respectively. Each of the optical multi/demultiplexing devices includes a supplying section for supplying the connection communication device with a specific one of the assigned optical signals that is assigned to the communication device. The supplying section may be a bandpass filter for allowing the specific optical signal to pass therethrough and supplies the specific optical signal to the connection communication device.
