Abstract

We experimentally demonstrate a 28.95 Gbit/s/λ PS-1024-QAM DFT-S OFDM over 40 km of SSMF in a low-cost IM-DD system. A 1.85 Gbit/s capacity increment is achieved using PS-1024-QAM format. To the best of our knowledge, this is the first time to employ high order PS-QAM format in OFDM modulation.
