[8023-10GEPON] Presentation on FEC for 10G
Dear All,
I am interested in putting together a presentation on FEC for 10G (serial)
PONs. Judging from the materials from the July meeting, I think that there
is some common support for the following basic ideas:
1. FEC should be applied at the very lowest layer (streaming-FEC).
2. FEC should be a mandatory part of the line code.
3. FEC codeword size should be aligned with the other EPON structure sizes
(such as 66b blocks and MPCP time quanta)
There are related topics that I don't think we've reached consensus on:
a. Choice of basic FEC algorithm (e.g, RS, BCH, etc.)
b. Line-rate increasing versus MAC-rate reducing approach
c. Code-rate and objective gain values
(some of these require collaboration with PMD specialists.)
If there are people who are interested in working with me on a presentation
on these topic areas, please let me know.
Sincerely,
Frank Effenberger

Subject: [8023-10GEPON] presentations for September meeting
Dear colleagues,
It appears that our next meeting will take place on September 18th and 19th
(Monday and Tuesday) and the High-Speed SG will meet on 20th and 21st, so
there will be no overlap and interested people will be able to attend both
meetings.
The meeting venue has not been finalized yet. A venue should be announced at
least 30 days before the meeting, so expect the announcement very soon.
Meanwhile, it is time to start working on presentations for the next
meeting.
There are many specific topics/features that we have to reach consensus on:
Downstream Wavelength
Upstream Wavelength
Power budgets
FEC: Optional or Mandatory
FEC Category: Stream-based vs. Frame-based
other topics - anything that is in scope of our PAR can be discussed.
If you can think of any other topic not listed here, please propose it on
the reflector.
If you have opinion on any of these or other topics, make a presentation
with arguments in favor of it. Remember, a proposal should have > 75%
support to get accepted as a baseline. It is a good idea to circulate
proposals on the reflector and get feedback, and to enlist additional
supporters.
Regards,
Glen
