Abstract :
We report on the long-haul transmission of 1-Tb/s superchannels using PDM-16QAM modulation and Nyquist pulse shaping. Based on flexible grid wavelength selective switch technology, we transmit three 1-Tb/s superchannels spaced by 175-GHz over 1600 km of SSMF and four ROADM, with a spectral efficiency of 5.7 bit/s/Hz.
