Abstract:
We demonstrated in-service transceiver calibration for 128-GBd PM-PCS-64QAM via adaptive multi-layer filters over 120-km SMF. After compensating the Tx/Rx-IQ difference only, Q-penalties of 0.1 dB with 2 ps Tx-IQ skew, 3 ps Rx-IQ-skew, 2 dB IQ peaking error, and 60-GHz Rx-IQ bandwidth imbalance were achieved.
