<p>An optical wavelength division demultiplexing apparatus for demultiplexing a multiplexed optical signal having a plurality of channels occupying respective wavelength bands. The apparatus comprising at least one waveband selector (10, 11) that acts to select wavelength bands corresponding to non-adjacent channels, the selected wavelength bands being routed to an associated array demultiplexer (30, 31) that outputs the selected wavelength bands as a parallel array of channels.</p> |
