200G QSFP56 SR4 • Unlike previous QSFP+ and QSFP28 optical modules that used Non-Return-to-Zero (NRZ) modulation, the 200G QSFP56 optical module employs advanced Pulse Amplitude Modulation with 4 levels (PAM4). PAM4 technology encodes two bits of all four states (11, 10, 01, and 00) using four different voltage levels within the same time unit, enabling PAM4 signals to transmit data at twice the rate compared to traditional NRZ signals. • #40g #200g #factory #datacenter #telecom #switch #5G #opticalmodule #opticaltransceiver #mvslink • #ai #router #firewall #fibretransceiver #nvidia #cloudcomputing #dac #aoc
