title = "25.6-Tb/s WDM transmission of polarization-multiplexed RZ-DQPSK signals",
abstract = "We demonstrate record 25.6-Tb/s transmission over 240 km using 160 WDM channels on a 50-GHz grid in the C+L bands. Each channel contains two polarization-multiplexed 85.4-Gb/s RZ-DQPSK signals, yielding a spectral efficiency of 3.2 b/s/Hz in each band.",
