Abstract
Employing optimized frequency packing over digital subcarrier multiplexing (DSCM), we exploit the mitigation of WSS filtering penalties. After transmitting a 60 Gbaud 8-DSCM with 0.2 roll-off over 5-10 WSSs, we experimentally demonstrate OSNR gains of >3 dB, without additional DSP complexity.
