摘要：
In a coupling arrangement for freely selectively switching through optical WDM (Wavelength Division Multiplex) signals, the input stage is formed with 1-x-m switching matrices, an optical signal with exactly one wavelength being fed to each 1-x-m switching matrix. In addition, the 1-x-m switching matrices and/or the space division multiplex switches of a central stage connected to the input stage are formed with semiconductor amplifiers (Semiconductor Optical Amplifiers). The coupling arrangement has the capability of switching through individual input signals in a non-blocking fashion to a plurality of output signals (multi-cast capability).
