Cascaded MIMO Equalizer for Transceiver IQ Imbalance Compensation in Ultra-High-Order QAM Coherent Optical Transmission
We experimentally demonstrated a cascaded multiple-input-multiple-output (MIMO) equalizer in the probabilistic shaping (PS) polarization division multiplexing 64/256/1024/4096/16384 quadrature amplitude modulation (QAM) coherent optical transmission. The 4096/16384-QAM raw spectral efficiency can reach 20.381 and 21.333bit/s/Hz, respectively.
