Re: [802.3_NGEPON] 802.3ca (100G-EPON) bi-weekly consensus - call for agenda items



Glen and all,

I would caution against thinking that “wavelengths” are like a commodity.  Unlike people, not all wavelengths are created equal, I’m afraid to say. 

Moreover, we don’t allocate individual wavelengths, but actually wavelength bands, with width of which has a huge effect on cost of components.  

This is what the presentations at the last meeting from Ed and I were getting at. 

 

The worst thing is that we are not starting from a clean slate – there is a lot of legacy there, and also other optics defined in the market that could be reused.

All in all, it is a very complex decision to make, and you can’t simplify it to “Keep the number of wavelengths to a minimum”. 

 

Other than that, your basic ideas of the fully flexible kind of system I generally agree with.  Indeed, my preso in Dallas suggested many of these same features. 

They are a nice ‘wish list’ at this point.  The killer question is: can we achieve all of them?  It’s not so clear to me now.

 

Sincerely,

Frank E.

Curtis,

 

I'd like to discuss the general architecture approach. We had a number of presentations in Dallas leading towards this approach, but since the Dallas meeting was per-TF, we didn't make any formal decisions. In Atlanta, we started looking into various low-level details, but the big picture is left undefined. My slides are attached. All feedback is welcome.

 

Thanks,

Glen

Dear Colleagues,

 

This coming Thursday, February 18, 11:30-1:00 Mountain Time, we will hold an IEEE 802.3ca 100G-EPON consensus building meeting. Please let me know by Wednesday noon (Mountain Time) whether you have requests for agenda time.

 

If I do not receive agenda requests by noon Wednesday, I will cancel the meeting.

 

Thank you!
