PAM4 is a modulation scheme that combines two bits into a single symbol with four amplitude levels as shown in Fig. This effectively doubles a network's data rate, enabling 400G/800G short-haul transmission. NRZ, or Non-Return-to-Zero signaling, represents binary information using two distinct signal levels: This creates relatively wide signal separation between logical states. As a result, NRZ systems historically provided: This operational tolerance helped earlier architectures remain relatively. PAM4 is a branch of the pulse amplitude modulation (PAM) technology, which is a mainstream signal transmission technology following non-return-to-zero (NRZ). Playing a key role in multi-order modulation, PAM is widely used in high-speed signal interconnection. Figure 1-1 shows the typical waveform. A key new modulation scheme, PAM4, was introduced around 2017 and enabled the big jump from 100G to 400G. 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.
