Re: [802.3_100GCU] [Fwd: Recommended channels to use]
You don't mention any channels that are near the limit with FEC. As PAM4 is expected to have FEC all the time I'd have thought we'd need channels above and below the limit with FEC.
Looking at what you say about the channels for PAM-2 I see that we potentially have the same issue for those channels as well for use with FEC.

folks,
At the June 7 channel model consensus group discussion i agreed to provide recommended channels to use for testing potential channel evaluation methods. Enclosed is a csv file with my recommendations for
PAM4 channels intended to work with FEC.
In the file i list 10 channels,
2 which qikSN says are definitely bad. Both are moderately short.
6 which qikSN says are near the limit without FEC, some
slightly above the limit, some slightly below.
2 which qikSN say are definitely good one short one moderately short.
I also include an updated list of NRZ channels as there were a few errors in the last set
