<p>A wavelength division optical switching system comprises a plurality of terminals (A,B,C,D) each generating a light signal on a particular wavelength division multiplexed channel and an optical multiplexer (10) connected to the terminals for multiplexing the light signals from the terminals. A processor (60) identifies the channel of a source terminal requesting a connection and the channel of a destination terminal. A reference light generator (70) generates a plurality of reference lightwaves of different wavelengths. A wavelength switch (30, 50) is provided for switching multiplexed channels by selecting the light signal of the identified source terminal channel and modulating the intensity of one of the reference lightwaves with the selected light signal so that the identified channel of the source terminal is switched to the identified channel of the destination terminal. An optical demultiplexer (20) is connected to the output of the wavelength switch for demultiplexing the switched multiplexed channels and applying the demultiplexed channels to the terminals, respectively.</p> |
