ABSTRACT:
An optical crossconnect includes optical elements (D1 . . . DM) for wavelength demultiplexing of optical signals and elements (MT) for optically processing the demultiplexed signals which give each optical signal a specific wavelength and bring to one of the outputs (S1 . . . SM) the signal with the specific wavelength under the control of a management unit (G). Such an optical crossconnect may find particular application in telecommunication networks.
