WDM transmission of 16-channel single-carrier 128-GBaud PDM-16QAM signals with 6.06 b/s/Hz SE

We experimentally demonstrate the WDM transmission of 16-channel single-carrier 1.024 Tb/s signals based on 128-GBaud all-ETDM PDM-16QAM signals over 320-km standard single-mode-fiber with EDFA-only amplification with joint transmitter and receiver-side signal processing.
