I’d rather do it as a package.

Frank, We are thinking along the same lines. However I propose that we take the motions one step at a time. Dekun and I drafted this motion, which only addresses two upstream options: 802.3ca shall adopt a wavelength plan with two 20 nm wide wavelength options for the first 25G upstream channel: 1.
“Plan A” option: center wavelength between 1300 and 1320 nm, exact value to be determined 2.
“Plan B” option: 1270 nm Only the “Plan A” option will be required to co-exist with 10G EPON. Your motion bundles in two downstream options, and I don’t think we have the same degree of consensus on that. What do you think of starting with the above upstream option motion, and then follow that with a downstream option motion, extracted
from your text below? Ed From: frank effenberger [mailto:frank.effenberger@xxxxxxxxxx]
I have some motions I would like to make.
Given that I think there is support for defining at least the first 25G channel, and that the ‘either or’ plan has a lot of support, I suggest:
802.3ca shall adopt a wavelength plan for the first 25G channel with two options, Option 1: downstream at 1358.4nm width 3nm, upstream at 1310nm width 20nm; coexistent with 10GE-PON Option 2: downstream at 1336.6nm width 3nm, upstream at 1270nm width 20nm; coexistent with G-PON reduced wavelength set.
Consequent to this motion, I propose another motion: 802.3ca shall add the objective: Wavelength allocation allowing concurrent operation with G-PON reduced wavelength set (1290-1330nm) PHYs Sincerely, Frank Effenberger |
