Quality Guarantee for PAM4 Active Optical Devices
Every 400G and 800G PAM4 transceiver ships with a single number called TDECQ — Transmitter and Dispersion Eye Closure Quaternary. It's usually the one line on the datasheet that decides whether a link runs clean for three years or starts flapping on a warm afternoon. It is a standardized measurement — defined under the IEEE 802. In practice, TDECQ expresses how much additional optical. In data center optics, 4-level Pulse Amplitude Modulation (PAM4) signaling is gradually overtaking Non-Return to Zero (NRZ) signaling. By encoding two bits in each symbol, PAM4 signals use half the bandwidth of the logic-emulating NRZ (non-return to zero) modulation scheme to transmit at the same data rate. Figure 1-1 shows the typical waveform.
