ABSTRACT:
An optical-wavelength interchanger element includes a branching section for bifurcating a wavelength-multiplexed input light signal having a multiplicity of an even number into first and second light signals. The interchanger element further includes a wavelength converting element for simultaneously converting wavelengths multiplexed in the first light signal so as to output a third light signal. The interchanger element further includes a transmission path for sending the second light signal therethrough without converting wavelengths multiplexed in the second light signal. The interchanger element further includes a joining section for combining the third light signal and the second light signal so as to output a wavelength-multiplexed output light signal. The interchanger elements may be connected in series in plural stages so as to form an optical-wavelength interchanger device.
