Proposal of a ROADM architecture for an elastic optical network based on O-OFDM

We propose a reconfigurable optical add/drop multiplexer (ROADM) architecture for an elastic optical networks (EON) that allows the traffic of all optical orthogonal frequency division multiplexing (O-OFDM) signals. This new ROADM setup is validated by a point-to-point simulation of a 100 Gb/s 4-subcarrier O-OFDM signal traveling through the light paths of an 8-node mesh network performing one add/drop operation at each node along the traveled distances.
