Those distances are firmly into the

Bear with me one more time as I drill down a little and spell things out.
I've realized that there may be more than one interpretation of "EoDWDM".
Are you referring to:
(a) Ethernet packets in OTU frames - thereby implying an underlying OTN?
(b) Ethernet optical SFP+ transceivers with a cable
Mark, when you write "There is a healthy sharing of the pie between DWDM
and packet to drive these Ethernet Metro's ", can you elaborate a little?
Are you referring specifically to EoDWDM, or do you have something else in
mind?

play a big part as well, somewhere between the Metro and the Access.

Hello,
I'm new to this mailing list. I hope I've understood the scope correctly!
I've posted this question to ResearchGate but I haven't had any response.
I'm hoping for some guidance from here.
The question is:
