Re: [802.3_NGEPON] IEEE 802.3ca Geneva Meeting - Day 3

All: It seems that in this wavelength plan proposal the 50G will be serial, regardless PAM4 or NRZ, and TDM coexist with 25G. There will be NO 2x25G =50G with channel bonding. There will be NO third 25G channel. 100G is achieved with 2x50G.  If so, it agrees with my contribution to this meeting  in dai_3ca_02a_0118  p.11.


I am at “Future Cable TV WS” in next building, so I’ll not vote but I support this wavelength plan.


PS. That means 802.3ca will end up with TWO 25GEPONs, and defers 50G to another project. Channel bonding is also deferred to 50G with 2x50G.

I would like to suggest a motion for the wavelength plan.  This is an update of my presentation from Orlando, reflecting the wavelength shift.


  • Wavelength plan
    • Channel A: 1358±1.5nm down, 1300±10nm up
      • WDM coexistence with 10GE-PON
    • Channel B: 1335±1.5nm down, 1270±10nm up
      • WDM coexistence with G-PON
  • 25 and 50G TDM coexist on both A and B
    • 25/10G ONUs would use same upstream as 25/25
  • 100G system would be A+B

Dear Colleagues,


This serves as a friendly reminder that the 802.3ca Task Force will meet for a third day today, room 15, CICG, starting at 9 am.


Thank you,
