Dear Marek,

This is Tsutomu TATSUTA from NTT.
Thank you for your great work. I think 10GEPON-D[1].0.7h is very useful
to understand this complicated work.

By the way, I have some comments and questions.
First of all, I made the attached file in order to understand relation
between a power budget and the spreadsheet. Basically I referred a white
paper whose title was "Review of the 10Gigabit Ethernet Link
Model" (I think this paper was sent from you). 

In my slide, I have some questions.
1. Is "Pc" a value of cell "S34"?
2. Which cell is representing item "M"?
3. "LP Pen central" (cell "V34") looks like
representing all of penalties. Is my understanding right?
4. "LP Pen central" is including cell "L34" which is
"P_DJ central". The white paper does not notify it. If question
no.3 is yes, do we need to include "P_DJ central" in "LP
Pen central"?

A following comment relates to your file.
5. Cell "B42" in file "10GEPON-D[1].0.7" is specified
as other_penalties which represents other system penalties. However a
value is derived from cell "L7" in file
"10GEPON-D[1].0.4_with_examples", which represents Connections
etc. I think this value should be included in ChIL and a penalty should
come from cell "V34".

Please forgive me if my understanding is irrelevant.

Sincerely yours,
Tsutomu TATSUTA

Dear all,
it is my pleaseure to inform You that a new version of the channel link model is available at: http://www.ieee802.org/3/av/public/tools/index.html
The list of introduced changes (non-exhaustive) includes the following items:

• Modified user interface - all typical user input was grouped in a single table
• The spreadsheet is locked by default (no password) providing access only to user input fields
• All tables with less frequently observed/modified parameters were moved to row 500
• Modified fibre attenuation curve selector - right now it is possible to use the previously existing model ("standard" in cell B24) or G652 AB/CD type of curves
• Added G652AB/CD fibre attenuation curves with min/max values to observe changes on the power budget in the function of fibre attenuation (set B24 to G652AB or G652CD and modify cell B25 to get min/max curves)
• Added curve type selector for PSC attenuation curve (cell B18) with 3 possible values i.e. min/max/average, as discussed in 3av_0611_hajduczenia_1.pdf
• Set-up the print area so that there is a table with parameters along with the charts
• Added uniform colour coding to indicate correct/incorrect/input/output cells
• Added Macro to allow the user to input Extinction Ratio and vary either Tx_Pave_dBm or TxPave_OMA (cells B4 or B5) - please allow macros in this document if You want to use this particular functionality
• Added 4 columns for upper and lower limits used in conditional formating in User input and Calculated Parameters tables.

I would appreciate all constructive comments on this issue.
Thank You and best wishes
