Re: [802.3_NGEPON] Call for agenda items -- weekly consensus building for IEEE 802.3ca (100G-EPON)

Ed,

 

I find discussion on slide 3 confusing, in that 10G US wavelength for 802.3ca devices, per your earlier slides, is around 1310nm, which makes sense, given previous discussions. On slide 3, you seem to imply that we really have two 10G US wavelengths that can be picked and chosen, as needed, depending on whether an operator plans to use 10/10G-EPON at all or not. Seems to me we are adding way too much rope for ourselves down the road, as far as number of different optical modules is concerned

 

I am OK with your Bfx and Bfg wavelength plans, but I do not see any need for Gf plan and added confusion to the table.

Here is the contribution on 802.3ca 10G US channels in greenfield.

Dear Colleagues,

 

We have at least one contribution for the 100G-EPON (IEEE 802.3ca) consensus building meeting scheduled for this Thursday, August 17, 11:30 am – 1:00 pm MDT.   

 

  • 802.3ca 10G US channels in greenfield – Harstead/Kramer/Johnson

 

Please let me know by 5:00 pm MDT Wednesday if you have any other topics for the agenda.

 

As a reminder from the closing report of our last F2F meeting in Berlin, the following topics were deemed important for contributions:

 

  • Actions:
    • Par/Objectives/Scope change
    • Power budget
      • Close on 25Gbps power budget (Ed/Dekun/Umeda)
    • MPCP/MPRS
      • Preliminary proposals for changes to channel bonding scheme (Duane, Glen)(Aug 31)
      • Discovery process / configuration / ONU capabilities field in RegREQ (Duane/Dan)
    • Fault Tolerance/Recovery/Loss of Channel
    • Wavelength plan
      • 2 versus 1 DS0 (Frank/EdH)(August 17)
    • SOA preamp/dynamic range
      • Cost and feasibility still needs to be demonstrated
    • Line coding (Postponed until after FEC decision)
    • FEC information
      • Comparisons of parity matrices and different FEC (Mark/Bill/Yin)
    • SERDES/CDR
      • Check margin for 10^-2 input BER (Yin, Ryan)
    • 50G single wavelength
      • Technical feasibility of upstream bursts (Critical path item) (Nokia) (likely September)
      • Wavelength plan
      • Power budget
      • Modulation

 

 

Thank you,

 

Curtis
