Experimental comparison of 1.28 Tb/s Nyquist WDM vs. time-frequency packing

We experimentally compared terabit transmission employing 16QAM Nyquist WDM and QPSK Time-Frequency Packing. The two modulation schemes have been transmitted over the same link configuration. The latter showed slightly better performance in terms of spectral efficiency and reach, at the expense of a more expensive and complex hardware.
