Real-Time 112Gb/s DWDM Coherent Transmission with 40% Extended Reach by Transmitter-side Low-Complexity Nonlinear Mitigation

Not Accessible

Your library or personal account may give you access

Abstract

One stage nonlinear digital pre-distortion and pulse-carving extend the transmission reach by 40% in real-time DWDM DP-QPSK transmission using digital coherent CMOS LSI. Practical robustness against link uncertainties was confirmed.
