When I was looking at something like this, this time last year, I got as
far as Packet Light:


https://www.packetlight.com/products/100g-200g-dwdm-transport/200g-single-wavelength-muxponder

A big part of my usecase was reselling the spare capacity, so I really
didn't want anything learning MACs at either end. :)

Unsure about those product lines, but I believe the Facebook (Adva?)
"Voyager" fits the 'open' bill. Here's a PDF specific to running Cumulus
on it:
