Demonstration of Bit Rate Variable ROADM functionality on an Optical OFDM Superchannel

: We demonstrate a bit rate variable add- and drop function performed on an optical OFDM superchannel signal by optical filtering and superposition of various OFDM subbands and the application of different modulation formats for dynamic networks. 2008 Optical Society of America OCIS codes: (060.1660) Coherent communications, (060.4230) Multiplexing
