Dual-polarization multi-band OFDM versus single-carrier DP-QPSK for 100 Gbps long-haul WDM transmission over legacy infrastructure

摘要

We experimentally compare the performance of coherent dual-polarization multi-band OFDM (DPMB-OFDM) and QPSK (DP-QPSK) for 100 Gbps long-haul transport over legacy infrastructure combining G.652 fiber and 10 Gbps WDM system. We show that DP-MB-OFDM and DP-QPSK have nearly the same performance at 100 Gbps after transmission over a 10x100 km fiber line.
