ABSTRACT:
The invention provides a wavelength division multiplexing optical transmitter wherein an unequally spaced arrangement of optical wavelengths can be realized readily and economically. The wavelength division multiplexing optical transmitter includes an optical transmission section for outputting a plurality of optical signals having wavelengths spaced by unequal distances from each other, and a wave multiplexer having an equally spaced wavelength optical multiplexing characteristic of multiplexing a plurality of optical signals having wavelengths spaced by a substantially equal distance from each other. The wave multiplexer being constructed such that, when the plurality of optical signals are inputted thereto from the optical transmission section, the wave multiplexer multiplexes the plurality of optical signals from the optical transmission section into a multiplexed optical signal and outputs the multiplexed optical signal. Also a wavelength division multiplexing-demultiplexing optical transmission-reception system which incorporates the wavelength division multiplexing optical transmitter is disclosed.
