The switching of signals is performed in the optical domain by routing the carriers through broadband and selective stars, by frequency conversion and tunable heterodyn-receivers. Experimental results of a switching element are presented and a simple calculation shows, that more than 10000 broadband carriers could be processed.enbroadband networksfrequency division multiplexingoptical communication equipmentoptical switchesreceiversbroadband exchangewdmfdmcoherent multi-carrier switchingfrequency conversiontunable heterodyn-receivers621conference paper
