Abstract
A proposed high capacity optical coherent multi-carrier (CMC) switching node for a broadband application is described. 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.
