Abstract
Switches (multiplexers, demultiplexers, data switches) are provided for optical signal transmission, by which two or more data streams are combined or separated or by which combined data streams are switched. Instead of buffering as in time-division multiplexing, wavelength conversions are performed. By space-division and wavelength-division multiplexing, storage problems can be largely avoided.
