Abstract
In a wavelength-division multiplex switching network having input wavelength-division multiplex (&lgr;) demultiplexers followed by a space switch and output wavelength-division multiplex multiplexers, wavelength-individual space switching matrices which are in each case connected, at the input end, via a number, corresponding to the number of wavelength-division multiplex multiplexers, of link lines to corresponding outputs of the space switch, lead to the wavelength-division multiplex multiplexers, some of the link lines leading to a space switching matrix directly connect the space switch to the respective space switching matrix and an adjustable wavelength converter is in each case inserted into the remaining link lines.
