Title: RE: [8023-10GEPON] FW: [8023-10GEPON] [POWER_BUDGET] ad hoc group meeting - CORRECTE D

Dear Tatsuta-san

Thank you for the slides describing IEEE and ITU_T terminology.

Regarding the ITU-T terminology, I have attached a re-drawn version of the slide which, I think, represents the meaning of the terminology used in ITU-T

Dear Robert and Marek,

Thank you for your arrangement.

I have some opinions about this issue.

I think our target is 29dB maximum insertion loss so far (See a result of the straw poll in November meeting, which is described in page 6 and 8 of http://www.ieee802.org/3/av/public/2006_11/3av_0611_closing.pdf).

So, at first, we need to decide the power budget, and it is derived from the spread sheet which Marek is making now.

I made a slide which described a relation between some numbers, which were defined in Tanaka-san presentation in November, and the spread sheet.

Also, I made a slide which described ITU-T terminology for your information.

Can we start to define the power budget?

Sincerely yours,

Tsutomu TATSUTA
