Re: [802.3_NGEPON] Proposed set of changes to Clause 56

Duane, Marek,
Relative to the comments on Item 1 below, wouldn't the mandatory FEC function still be defined in CL 142 for the "802.3ca" 10G rate that could share the "first" 25G US wavelength in a TDM manner that we're defining as part of this standard? i.e. - not the standard 10G EPON rate or upstream wavelength.

Regards,
Bill

Thank you, Duane

 

Item 1) will be fixed and it was clearly a mistake on my end.

 

As far as item 2) goes, this change will affect all new clauses as well – I think it would be better to have a comment on this topic against D1.1 to make sure it gets addressed correctly.

Marek,

Only noticed two items of importance:

  1. Pg 1/35 line 53 “Nx25G-EPONs using the nominal bit rate of 10, 25, or 25 Gb/s use a mandatory FEC function defined in Clause 142 in any direction.”  Probably not for 10G and the 2nd “25” should be “50” I suspect.
  2. For Fig 56-5a pg 2/36  We should add a note to these figures that 10G US will not use 25GMII but 10GMII in US.  Let me know if this needs to be a separate comment.

Best Regards

Duane

Dear colleagues, 

 

Attached please find the proposed changes against Clause 56 to accommodate Nx25G-EPON in the EFM architecture. All changes to Clause 56 material (where needed) are tracked in terms of additions and deletion. Material that does not need to be modified is NOT included in this contribution. 

 

I plan to submit a comment against draft D1.1 (once published) including this material as a contribution towards the draft. Please review and provide feedback. Your review is more than welcome.  

 

regards

 

Marek
