MZM Optimization of PAM-4 Transmission in Data Center Interconnect

MZM Optimization of PAM-4 Transmission in Data Center Interconnect

An analog optimization of 4-level pulse amplitude modulation (PAM-4) signal is proposed, together with maximum likelihood sequence estimation digital signal processing. The proposed optimizations are verified by experimental demonstration at 53 Gbaud, indicating an improvement of 4⁻5 dB in...
