While preparing for the Pittsburg meeting last week, I became very frustrated in trying to compare all of the experimental data presented in support of the differing SMF proposals.

The results were often presented using different receiver parameters (average power, outer eye OMA, inner eye OMA, etc) and with different receiver implementations/specifications.

This made it extremely difficult to easily compare the different experimental results.

I decided to take all of the experimental data presented in the task force, capture it in a single spreadsheet, and convert everything to inner eye OMA sensitivity (and at a 2e-4 BER) to make it easier to compare.

As a second step I applied a correction factor to all of the measurement data (where possible) to enable a comparison based on a common set of receiver specifications that are projected to be available in realizable products for 25Gbaud and 50Gbaud systems in the time frame of the 802.3bs project.

I shared this analysis with several people yesterday and they suggested it would be worthwhile sharing it with the task force.

As a result I captured my analysis in the attached presentation.
