Analyzing Network Reliability up to 800G

This presentation investigates the proximity to a low Signal-to-Noise Ratio (SNR) threshold that can still maintain a tolerable Bit Error Rate (BER) in 100G, 400G and 800G network links. Accounting for environmental factors such as temperature and cable length, the analysis compares the reliability of coherent (16QAM) and non-coherent (PAM4) transceivers — offering practical, data-driven insights into predicting sustained network performance between high-speed transceivers.
