the switch-and-select stage, the bandwidth of the optical signal is narrowed by two microring filters. We investigate this effect by injecting an Erbium-doped fiber amplifier (EDFA)-based broadband
Guide On Using PAM4 Modulation
Note that proper comparison of PAM5 and PAM4 would require specific proposals for PAM5 implementation, but it is unlikely that such comparison will be more favorable to PAM5
Guide PAM4 Signaling for 56G
Early Pioneers in PAM4 SerDes About a dozen years ago there were two PAM4 SerDes designs out there, by Rambus and Accelerant, respectively, targeting 6-10Gbps applications

The right part of this figure compares the eye diagrams of NRZ and PAM4 signals, where an NRZ signal uses the single-pupil waveform and a PAM4 signal uses three-pupil wavelength (three eye diagrams
Guide The Road from 1 Gbps-NRZ to 224 Gbps-PAM4
Just around 10 years ago, the march from 28 Gbps-NRZ to 56 Gbps-PAM4 began affecting transmission line design while representing an important signaling change in modulation from NRZ to PAM4. With
