Experimental Demonstration of ROADM Functionality on an Optical SCFDM Superchannel

In this letter, we experimentally demonstrate reconfigurable optical add-drop multiplexer (ROADM) functionality on an orthogonal band multiplexed (OBM) single-carrier frequency-division-multiplexing (SCFDM) superchannel. As far as we know, this is the first time that ROADM functionality for individual band with frequency spacing of 10 GHz is realized.
