Multi-Band OFDM versus Single-Carrier DP-QPSK for 100 Gbps Long-Haul WDM Transmission

We experimentally compare the performance of coherent DP-MB-OFDM and DP-QPSK for 100 Gbps long-haul WDM transport. We show that, after transmission over 1000 km of DCF-free G.652 fiber line, DP-MB-OFDM and DP-QPSK have nearly the same performance at 100 Gbps.
