Dan, I agree completely. Anyone misreading my email is apparently not understanding that things must be covered by a motion to be a position of a study group or even task force. I was very clear about the authors and supporters of a position taken in a contributing presentation. Jeff From: Daniel Dove [mailto:ddove@xxxxxxx] Hi Jeff, Some people have received your comments as suggesting that the entire Optics SG endorsed the position of that presentation or the key takeaways. I reviewed your comment and do not see you making that case, however, the title of the email might be suggestive of that. I am pretty sure you did not intend to suggest that, but a title like "System View on Optics - No AN for FEC" might have avoided even the most subtle implication. But just for clarity's sake, I will assert it very concisely. "The position stated in that presentation does not reflect the position of the entire SG. The Next Generation Optics SG has not taken a position yet." I am 100% sure you will agree with me on that. Hopefully in our next meeting, we can get some straw polling or motions to adopt language on this question. Regards, Dan From: Jeffery Maki <jmaki@xxxxxxxxxxx> For those of you who were not in the 802.3bj task force meeting this morning, I wanted to make clear that I sent the message below in response to questions at the microphone this morning regarding whether auto-negotiation of FEC is needed or wanted for optics. Jeff From: Jeffery Maki All, In the NG 100G Optical Ethernet Study Group this week, the presentation http://www.ieee802.org/3/100GNGOPTX/public/jan12/traverso_01_0112_NG100GOPTX.pdf was made by Gary Nicholl with the key statement: If new PMD(s) employ FEC, preference is that it is mandatory –Low Latency FEC is preferred –Proliferation of FEC types is burdensome Auto-negotiation is not sought. The presence or lack of presence of FEC is considered to be a separate PMD. See slide 11 on how to manage FEC over various PMDs.
