Re: [8023-10GEPON] [CHANNEL_LINK] New Excel spreadhseet available ...
Dear Marek,
This is Naoto Saeki of NEC.
Thank you for your great work to update the spread sheet for 10GE-PON.
I am trying to understand this complicated spread sheet and add
dispersion penalty by LD charp.
Please find attached pdf file and comment me.
I have a basic question for relevancy between spread sheet and standard
document.
Frankly say, is it needed to define a specification value in standard ?
or just tool for help to understand and estimate optical link model?
I would like to know which parameter should be defined by the spread sheet.
I can only find the value of TDP that may have relevancy to the spread
sheet. If so, how can we estimate TDP for 10GE-PON.
In my understanding, TDP for 802.3ah was defined with experimental
validation.
How accurate the value of TDP in the spread sheet?
I hope you will advice me on this topics.
Best Regards,
Naoto Saeki
