Abstract :
We experimentally demonstrate a 470.4-Gb/s superchannels consisting of 16 × 29.4-Gb/s densely-spaced OFDM/OQAM transmission over 2400-km SSMF with a novel alternative signals PAPR reduction scheme. With the nonlinearity improvement, an improvement of about 1 dB in Q factor and 1.5 dB in launch power over conventional OFDM/OQAM.
