Curtis: First a few general comments.
1. "To attempt approval in November, we must agree (via Study Group vote) at Interim in Florida." With this target it means that we only have one SG meeting to move to the TF. It this realistic? Or are we really in such a hurry?
There are several very different architectures to achieve beyond 10G in EPON, single lane 25G, single lane 40G, multi-lane 40G (4x10), multi-channel 40G (4x10G hybrid WDM-TDM), etc. Without sold feasibility studies of any of these how can we pickup one at first F2F meeting?
2. "Agreed objectives". At this stage without a formal F2F or even a formal Ad-hoc it is too immature to say "agreed". It is likely that we'll have more people at the interim meeting, what is agree by now may not be true by then.
A few more comments on the "agreed objectives":
1. Objective 1. "Support subscriber access networks using point to multipoint topologies on optical fiber".
Should be ...on single mode optical fiber".
2. Objective 3. "Support power budgets equivalent to power budgets defined by EPON in 802.3-2015"
When move to higher rate, such as 25G or 40G, we need consider: a). higher splitting ratio may be needed to more effectively use the bandwidth, b). at 40G, dispersion on SFM may need to be considered, c). if advanced modulation such as PAM4 is used, its impact on power budget need to be considered, d). if hybrid WDM -TDM is used, the extra loss of WDM filters need to be included...
3. Objective 4 essentially means that we want both 25G single lane and 40G (single-lane or multi-lane) solutions. This is debatable.
4. Should we add coexistence objective? The answer is definitively yes. The question become complected if we adopt 25G and 40G, possibly multi-lane, at the same time which point back to my question on the objective 4.
