Re: [8023-10GEPON] power saving Ad-hoc
Dear Suzuki-san,
Indeed You're correct.
100BASE-T for GPON and EPON
1000BASE-T for 10G-EPON
Please update the table as necessary.

Dear Jeff,
Thanks for your effort.
I'd like to confirm the definitions of "UNI-Ethernet" in your table.
I think you means UNI-Ethernet's for G-PON and EPON as 100BASE-TX and
"UNI-Ethernet" for 10G-EPON as 1000BASE-T. Is that right?
Best regards,
Ken-Ichi

It would be nice if this document gets extended with time, with people introducing values they feel comfortable with and which can be confirmed. Please note that the values I included in the table are for discrete component systems and are worst-case ones. SoC designs can have much power consumption figures (I saw data sheets for 2 W ONU units, though it is hard to estimate consumption of individual ONU elements in such a case.)
