A 62Tb/s Transoceanic Transmission Experiment Using Probabilistically-Shaped PDM-64QAM
26 August 2016
We report on a C+L-band transmission of 62 Tb/s over 6600km using 49 GBd probabilistically-shaped 64QAM (PS64QAM) modulation format, digital-back propagation based nonlinear compensation, and adaptive-rate spatially-coupled LDPC decoding. We compare the performance of PS64QAM with that of 32QAM.
