Web21 de jul. de 2024 · Comparison of PAM4 vs. NRZ. In a nutshell, NRZ is a modulation technique with two voltage levels to represent logic 0 and logic 1. The voltage literally does not “return to zero”; logic 0 is a negative voltage, and logic 1 is a positive voltage. PAM4 uses four voltage levels to represent 4 combinations of 2 bits logic: 11, 10, 01, and 00. dwight on fear the walking deadWeb1 de jun. de 2024 · We have demonstrated a stable UWOC system based on an AOM and a single-mode pigtailed 520 nm green LD using NRZ-OOK modulation.
