Analyzing network reliability up to 800G - Impact of SNR thresholds on BER for Coherent (16QAM) and Non-Coherent (PAM4) high speed transceivers under environmental variations
2024-11-18 , Auditorium

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 / 800G network links. Additionally, we account for factors such as temperature and cable length to predict the duration for which a reliable network connection can be sustained between transceivers. The analysis, based on data retrieved using a Flexbox, focuses on comparing the reliability of coherent (16QAM) and non-coherent (PAM4) transceivers, with a detailed discussion on the implications of these technologies on network performance. For a better understanding of the correlation between these factors, Machine Learning techniques were used.
