Record-High 17.3-bit/s/Hz Spectral Efficiency Transmission over 50 km Using Probabilistically Shaped PDM 4096-QAM
11 March 2018
We demonstrate transmission of a 10-subcarrier superchannel with a record-high intra-channel spectral efficiency of 17.3 bit/s/Hz over 50-km backward Raman amplified Corning Vascade EX2000 fiber using 3-GBd probabilistically shaped PDM 4096-QAM.
