PAM4 Pakistan Telecom-Grade Router
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. PAM4 is a branch of the pulse amplitude modulation (PAM) technology, which is a mainstream signal transmission technology following non-return-to-zero (NRZ). But to understand why it has become ubiquitous in serial data standards, you first must understand the market forces driving the data networking industry.
