Accurate Beyond-400G Transmitter Quality Metric Based on Transmitter Constellation Closure Measurement (Th2A.26)
Presenter: Qirui Fan, Huawei
We demonstrate the use of transmitter constellation closure (TCC) for accurate quality assessment of beyond-400G coherent transmitters, and show its tolerance to inter-symbol interference and phase noise with and without probability constellation shaping (PCS).
