TDECQ stands for Transmitter and Dispersion Eye Closure Quaternary. It is a standardized measurement — defined under the IEEE 802. It measures the increase of optical power required. However, a new metric called TDECQ has emerged as a more comprehensive way to characterize transmitted and received signals in the optical domain. TDECQ essentially measures the vertical eye closure of an optical transmitter after the signal has traveled through a simulated worst-case optical. TDECQ — Transmitter and Dispersion Eye Closure Quaternary — is the key metric for PAM4 transmitter qualification and is now a mandatory compliance measurement for 400G and higher-speed optical modules. Optical modulation amplitude (OMA) indicates the strength of the modulation power. For legacy NRZ systems, eye-mask tests place polygons below, within, and above the NRZ eye diagram and verify where the. In data center optics, 4-level Pulse Amplitude Modulation (PAM4) signaling is gradually overtaking Non-Return to Zero (NRZ) signaling.
