On the Bit Error Rate Fluctuation Induced by Multipath Interference in the Coherent Regime for Intra Data Center Applications
Wing-Chau Ng, Scott Yam
TL;DR
This paper provides a theoretical explanation of how multipath interference affects PAM-4 signals in coherent intra data center communications, leading to increased bit error rate fluctuations.
Contribution
It is the first work to analyze the impact of multipath interference on PAM-4 constellation resizing and BER fluctuation in coherent intra data center links.
Findings
Multipath interference causes PAM-4 constellation resizing.
Bit error rate fluctuations are significantly increased due to multipath effects.
Theoretical model explains the BER fluctuation phenomenon.
Abstract
We theoretically explain how multipath interference resizes PAM-4 constellation in the coherent regime and thus increases bit error rate fluctuation in intra data centers for the first time.
