Frank
E.;
Very
nice initiative, and great strawman proposal on top of the group consensus so
far.
Quick
comments for consideration to further tweak the numbers:
- I suggest to include the baseline ER, the group still need to
agree on somewhere.
- Suggest channel loss reflect the wavelength dependence for US and
DS.
- I think the group has some consensus to budget FEC coding gain
separately (in particularly for pin or apd).
- Allocation of 1dB penalty for all confg is too loose, for
further consideration, suggest D/S include the jitter budget, while U/S add
extra BM penalty (with fiber).
- Take the dynamic range requirements into account for each confg
before specifying overload specs. PR30 DS overload of -10dBm sounds
unnecessarily loose.
- Specified the guaranteed corners (temp./ps range) in
considering worst-case numbers, for example I feel DS 3dB launch power
variation is not enough.
thanks
for considering

Dear All,
Per request of the chairman, I
have compiled the loss budgets as best I can assess them.
In doing so, I have attempted to
minimize the number of distinct component levels.
Please take a look, and comment
freely on the exploder.
Sincerely,
Dr. Frank J.
