MPLS? That's like trying to use a sledgehammer to open a pickle jar. Sure, it might get the job done, but it's gonna make a huge mess in the process.

Metro Ethernet? That's like trying to use a toaster to heat up your house. Totally the wrong tool for the job. DWDM is the obvious choice here.

MPLS? Really? That's like trying to fly a plane to the grocery store. Totally overkill for this use case. DWDM is the way to go, hands down.

I'm not sure why CWDM is even an option. DWDM is clearly the superior technology for a large-scale, long-term project like this. It's like trying to use a spoon to dig a hole - just doesn't make sense.
