[EFM] FEC proposal - conference call
In the last EFM meeting we adopted a motion:
"to add an FEC option for the 1G P2P and P2MP PHY. This option will maintain
backward compatibility with 1000BASE-X PCS. We added this FEC option because
we agreed that FEC - (1) Improves reach of a MPN limited link by 50% for
links with MPN penalty of about 2 dB, and (2) Permits operation at a SNR
lower by 2.5 dB for non-dispersion limited links."
I would like to open a discussion on the baseline proposal to combine FEC in
1G P2P and P2MP keeping backward compatibility with 1000BASE-X PCS.
A link to such a proposal is attached:
In this paper several issues are referred:
- Framing keeping compatibility:
- State machines for Sync, Tx, Rx.
- Mean time to false packet acceptance.
I would also like to schedule a conference call to discuss the FEC proposal.
I suggest this time and date for the call:
Date: Monday June 17
Time: 1:00 PM EDT
I will provide the bridge number and access code later.
It is important that we shall consolidate behind a proposal and it is
required that it would be widely supported. Your participant in this process
For those of you who were not following the FEC effort from its beginning I
attach a link to the FEC presentations in EFM so far. This presentations
provide a fine tutorial on FEC capabilities and possible implementations.
