Hi Adrian

 

That makes sense. I won’t reschedule a conference call for this.

 

I didn’t ask for a Joint T11.2/T11.3 meeting in August but we can schedule this in the FC-PI-7 ad hoc and make sure everyone knows when we will discuss it in case of the T11.3 people want to attend to listen.

 

REGARDS DEAN

Hi Dean (et al),

 

Based on factoring in the use of Precoding for 256GFC links & an initial review of the associated Ethernet error modeling results, I don't believe there is a need to consider anything as extreme as a signal processing architecture change for FS-5 - So I don't plan to further suggest such an option. Instead, I would rather focus on analysis of the available Ethernet error modeling results to quantify BER differences between the 64GFC & 256GFC vs 50GbE & 200GbE architecture approaches. It may be useful to consider such data in the context of optimally managing 64GFC & 256GFC links. In view of that change in direction, Scott Kipp suggested (& I agree) that presenting such a contribution would best be done at the August Joint T11.2/T11.3 (& perhaps also at the T11.2?) ad hoc rather than an off-cycle conference call. Beyond that, since my current contribution T11-2018-00199-v000 is essentially invalid, I'm thinking it best if I delete that from the T11 data base so as not to propagate bad information.

 

In the meantime, for anyone interested in supporting &/or reviewing the analysis contribution I'm preparing, please send me a note advising of your interest so I can loop you in. Any feedbsck you may have to offer would be much appreciated!

 

Thanks & Regards,

Adrian

HI Adrian

 

I will cancel the meeting on the Website and send a cancelation notice out to the reflector (beside this one). We can reschedule when you are ready.

 

Speedy recovery!!

 

REGARDS DEAN

Howdy Adrian,

 

Thanks for the update, Dean will reschedule, and take care of your eye(s) 👍

Hi Folks,

 

Based on some very important feedback provided by Mike Dudek (thanks Mike!), there is a fundamental functional difference between 256GFC & 200GbE which I overlooked in the current document posting (e.g. use of Precoding for 256GFC). This renders much of the analysis & conclusions in the current posting invalid. I've been working on an updated document version which properly accounts for Precoding. However, those updates are not yet complete. It also hasn't helped that I'm currently recovering from emergency eye surgery last Thurs night (scary stuff!), so I'd suggest the Tues ad hoc for this discussion be deferred to a later date. Once the updates are complete, I'll post the revised version - And thereafter we can plan a new time for the joint call. Apologies for the late notice...

 

Regards,

 

Adrian
