Re: [8023-10GEPON] Revised 10G budget
Dear Colleagues,
I am surprised by the lack of discussion following Dr. Effenberger's last posting of an updated PMD proposal. I hope the right explanation for this is that the task force is in agreement regarding the proposed PMD parameters and no one has any concerns, questions, or alternative proposals.
If my explanation is correct, please add your name as a supporter of this presentation. However, if you have any concerns or questions, please do not be silent and discuss this on the reflector now.
If you do disagree with any of the proposed parameters, please validate your concerns and/or post an alternative proposal.
I sincerely hope that we will not have a repeat of the situation where some people refrain from raising any concerns between the meetings, but argue against accepting any proposal at the meeting on the basis that more studies were needed. Now is the time to ask questions and do additional studies.
Our hottest item for November meeting is reaching consensus on enough PMD parameters such that we can produce draft 1.0 and initiate task force review phase.
Thank you,
Glen Kramer
Chair, IEEE P802.3av Task Force

Subject: [8023-10GEPON] Revised 10G budget
Dear All,
I have taken some of the comments I received on my last Email, and modified the slides to come to the attached version.
What I’ve done is:
1. Reduce the PR10 OLT downstream transmitter Max and Min by 1 dB. (This reverts to the values presented in Takizawa’s slides in September)
2. Reduce the PR10 ONU Rx overload number by 1 dB. (Following the Tx change)
3. Increate the PR20 OLT max power by 1 dB (Makes the Tx range 4 dB, which is more comfortable)
4. Increase the PR20 ONU Rx overload number by 1 dB. (Following the Tx change)
Taken together, these changes then make the PR10 and PR20 ONUs identical in every respect. One less PMD!
This is re-capped on the last slide.
Sincerely,
Dr. Frank J. Effenberger 弗兰克 埃芬博格
