TLDR
In this article , a single-segment travelling-wave SiP IQ modulator at 105 Gbaud DP-64QAM was used to achieve 1 Tbps (line-rate 1.26 Tbps) transmission with all-electronic equalization and non-linear pre-distortion.Abstract:
We achieve net 1 Tbps (line-rate 1.26 Tbps) transmission using a single-segment travelling-wave SiP IQ modulator at 105 Gbaud DP-64QAM below the 25% SD-FEC-threshold over 80 km of SSMF with all-electronic equalization and non-linear pre-distortion.read more

System Optimization of an All-Silicon IQ Modulator: Achieving 100-Gbaud Dual-Polarization 32QAM
TL;DR: It is shown that nonlinear processing at the transmitter, in this case an iterative learning control (ILC) method, is essential as post-processing alone could not achieve reliable communications at 100 Gbaud.
