High Information Rate of 128-GBaud 1.8-Tb/s and 64-GBaud 1.03-Tb/s Signal Generation and Detection Using Frequency-Domain 8×2 MIMO Equalization

Abstract

We demonstrate 1-Tb/s and 1.8-Tb/s net rate signals with 16- and 14-bit/4Dsymbol information rates at 64 and 128 GBaud by precisely equalizing transmitter- and receiver-side imperfections with frequency-domain 8×2 MIMO linear equalization and nonlinear pre-distortion. © 2022 The Author(s)
