Thanks for the link. I confess I'm a little amazed that Infinera is the basis for running 100G coherent single wavelengths. That's great progress. (Edit- See below)
Essentially the issue with upgrading over the wet plant is basically the presence of nonlinearities on the fiber
Yes, and there's great incentive to utilize legacy fiber if possible.
(BTW I managed to screw up my comment above when I edited. I had written: Usually the undersea guys are a generation behind, partly because of the need to send a destroyer-looking ship out for any repairs.)
Yes. It's a 100G service though. Infinera runs on 25G spacing so at 25G dual wave dual polarization is 100G in the same spectral efficiency as single wave.

Hello! and hope all is well, whoever you are. :)
Edit: The infinera 500G PIC in the PR from Telstra is running its basic bitstreams at 25G and muxing them up - http://www.lightreading.com/optical/dwdm/infinera-unleashes-...
