In-Service Transmitter Calibration via Offloaded 4×2 WL MIMO Equalizer with Compensating IQ Imbalance

In-Service Transmitter Calibration via Offloaded 4×2 WL MIMO Equalizer with Compensating IQ Imbalance

In-service Tx-IQ imbalance calibration estimated with 4×2 MIMO equalizer for 96-Gbaud PM-PCS-64QAM was demonstrated over 120 km SMF. Q-penalties of 0.1 dB with 2 ps IQ skew and ±2.5 dB IQ peaking error were achieved.
