With a new generation of "56-112 Gbps components" of varying performance levels coming to the market, distinction and selection is increasingly important yet very difficult. Categorizing components using traditional frequency domain responses does not always correlate to channel performance, as the channel takes a holistic time-domain simulation approach to compliance. This paper explores data-rate and spectral content dependent component evaluation that is sensitive to the nuances important to channel performance. Using component level Effective Return Loss (ERL), Integrated Crosstalk Noise (ICN) and their interaction, a diverse set of components are evaluated and quantitatively correlated to the respective 56-112 Gbps channel performances.


Design, optimization and component selection metrics to consider for 112 Gbps PAM4 systems. The metrics suggested in this paper are aimed at reducing design times by identifying the metrics to focus on while simultaneously increasing confidence in components selected by correlating the said metrics to industry leading channel characterization methods.
