At the center of this shift lies PAM4 modulation, which has become the only practical path to achieving 100G transmission within the physical and thermal boundaries of the SFP form factor. Understanding 100G DSFP therefore requires tracing the evolution from NRZ to PAM4, examining the physical. PAM4 (4-Level Pulse Amplitude Modulation) is a four-level modulation method where each symbol carries 2 bits of information, doubling the spectral efficiency compared to NRZ's 1 bit per symbol. Figure 1-1 shows the typical waveform. AN 835: PAM4 Signaling Fundamentals - This application note explains PAM4 theory and its operation. When it comes to enabling 400G and higher Ethernet speeds, a four-level pulse amplitude modulation or PAM4 multilevel signaling is needed as opposed to the non-return-to-zero (NRZ) modulation.
