[802.3_B400G] Reminder - IEEE P802.3dj May Interim Presentation Request

All,

At the May interim a request will be made to the 802.3 WG for us to proceed to Working Group ballot. 

Please note that while we won’t need to spend time on comment resolution, as noted in the Task Force meeting announcement, pending time availability, the agenda would include preparation / consensus building for WG ballot.  This meeting will be our only opportunity going forward for the foreseeable future that can be used as a working session on issues, as the other meetings will be used for addressing comments during WG Ballot. 

Below is a list items identified by the Track Chairs as potential topics for discussion.  Individuals wishing to present are directed to use the following form:  https://forms.gle/9y3JBHgVFPgzVHbr5.  

For the IEEE P802.3dj Task Force Session, requests for presentation time shall be made by Thursday 01 May 2025. 

Logic Track

·       ILT protocol validation  (simulation or test data)

·       Delay constraint validation (additional analysis or test data)

·       FLR budgeting revisit for 800GBASE-ER1 (to support universal host)

·       FEC Degrade signaling validation for FEC sublayers (analysis, test data)

Electrical Track
