173.7-Tb/s Triple-Band WDM Transmission using 124-Channel 144-GBaud Signals with SE of 9.33 b/s/Hz

We demonstrate 173.7-Tb/s 101-km transmission in an 18.6-THz bandwidth, achieving a 9.33-b/s/Hz spectral efficiency at 144 GBaud with 124-WDM channels of net bitrates between 1.18 and 1.54 Tb/s/wavelength using entropy and code-rate optimized PCS-64QAM signals.
