Transoceanic PM-QPSK Terabit superchannel transmission experiments at Baud-rate subcarrier spacing

Abstract

We show experimental results on the transmission of a Terabit superchannel, consisting of 10×120-Gb/s PM-QPSK densely-packed subcarriers. We reached 10000km with 1.1×Baud-rate subcarrier spacing and 9000km with Baud-rate subcarrier spacing. We also reached 8000km with 3 superchannels at 1.1 spacing.
