PAM4 — The High-Speed Signal Interconnection Technology of Next-Generation Data Center
What Is PAM4? PAM4 (4-Level Pulse Amplitude Modulation) is one of PAM modulation technologies that uses 4 different signal levels for signal transmission. Each symbol period can represent 2 bits of logic information (0, 1, 2, 3), that is, four levels per unit time. In the data center and short-distance optical fiber transmission, the modulation scheme of NRZ is still…
