PAMn vs Channel and FEC Investigations for 224 Gbps
Simulations have shown that with reasonable channel IL (i.e.,~30dB IL, and ≤3dB ILD, at the PAM4 Nyquist), and a transceiver design (die and package) that works well at PAM4 rate, PAM4 would out
PAM4: Pulse Amplitude Modulation Explained | Keysight
Pulse amplitude modulation builds upon this concept by encoding data across multiple voltage levels. PAM4 uses four levels. A PAM4 signal can

Experimental Demonstration of FTN-NRZ, PAM-4, and Duobinary
The results indicate that FTN-NRZ, PAM-4, and ODB can be used for 100G-EPON with 10-Gbps optics, and FTN-NRZ has better performance than other modulations, which is more suitable for next
PAM4 Transmitter Analysis
PAM4 analysis package provides a comprehensive set of measurements that offer greater insight into signal characteristics, speeding up validation or characterization of PAM4 designs.
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

PAM4 Demystified: The Basics of Four-Level Pulse
PAM4 is a four-level pulse amplitude modulation method that transmits two bits per symbol, doubling data rates for high-speed networks.
PAM4 Signaling in High Speed Serial Technology: Test
Since CTLEs are passive filters, they''re no different in PAM4 systems than in PAM2-NRZ systems, but with four symbol levels, the decisions that PAM4 DFEs feedback are more complicated.
