Re: [802.3_NGEPON] Upstream Wavelength Plan

[Marek Hajduczenia <mxhajduczenia@xxxxxxxxx>]

That might James' opinion. I do not share it. We have enough spectrum to optionally allow WDM coexistence between 25G and 10G systems. 

At the end of the day, I personally do not care about new 10G upstream, but only about making both 25G channels equally challenging and limit their dispersion penalty. I do know though that the optional ability to do 10G and 1G upstream separation in today's system is a saving grace in many deployments where these systems are overlapped on the same fiber strand. I do not see any advance of doing the overlap if we can have some separation between these systems

Marek,

zhang_dezhi_3ca_2a_1117 proposed the principal that different rates in the same PON generation should share spectrum by TDM.  I think that this principal should apply to 25G and 10G (using 25G protocol) upstream.

Ed, please add me to your list.

Regards,

John

Ed et al.,

 

Here are two versions of what I was suggesting, depending on how we want to stack red 25/10G options

 

Please include me in the discussion chain.

 

Thanks
