Abstract

We experimentally compare the WSS filtering tolerance of single-carrier (SC) and digital subcarrier multiplexing (DSCM) at 95-105 Gbaud. Whereas DSCM tends to be advantageous when using excessive baudrates, the two modulation options yield similar performance if the baudrate is optimized.
