So right Jaredmagic has been in the NPU capacity increase that's driven
the cost per 100G down on 1RU routers; and the integration of DSPs and more
into QSFP-DD form factors at much lower power than expected. The standards
for optical links are maturing as well, but we still have work to do on the
management side for the electrical interfaces.

Re: Routed optical networks

[Eve Griliches]

Hi Etienne,
Below is our (Cisco) definition of the Routed Optical Network. The goal,
metro or long haul or subsea, is to reduce the number of control planes. By
migration TDM traffic using CEM or PLE to the IP layer, you eliminate the
OTN control plane and management. Eventually, when standards are settled
the ultimate goal is to have a single control plane for the network. I'm
not trying to be a commercial here, but you can read more in the resources
section on this page:
https://www.cisco.com/c/en/us/solutions/service-provider/routed-optical-networking/index.html
HTH,
Eve

Routed optical networking, is an architecture that delivers improved
operational efficiencies and simplicity. The solution works by merging IP
and private line services onto a single layer where all the switching is
done at Layer 3. Routers are connected with standardized 400G ZR/ZR+
coherent pluggable optics.

With a single service layer based upon IP, flexible management tools can
leverage telemetry and model-driven programmability to streamline lifecycle
operations. This simplified architecture integrates open data models and
standard APIs, enabling a provider to focus on automation initiatives for a
simpler topology.

Re: Alien waves

[Eve Griliches]

If your emphasis is on subsea operators, the content providers likely have
the most alien wave deployments due to the open cable initiative.
With transponders being more plug and play to operate over incumbent subsea
line systems, it makes it easier to deploy the latest and greatest
hardware; often done via an alien wave. However, some vendors charge
licenses for this, negating the benefits. Link below to open cables
