625 Gbit/s superchannel consisting of interleaved DP-16QAM and DP-QPSK with 4.17 bit/s/Hz spectral efficiency

We experimentally investigated a superchannel consisting of 25 GHz spaced interleaved 3×18.67 GBaud DP-QPSK and 3×18.67 GBaud DP-16QAM. We showed a 0.3 dB improvement in the Q-value averaged over the center two channels compared to an all DP-16QAM superchannel with the same SE after transmission over 480 km and 560 km of SSMF.
