Hello,
Depends on the equipment but works just fine. I have tested Ciena
Waveserver/AI and Ekinops equipment as alien wave into an existing Cyan
ROADM system without a problem. Usually just make sure your TX power is 0
or +5 + whatever the minimum for the ROAM system to pick it up.

My point was that the technology has little to do with the operational
success of the service. Spectrum controllers better enabling providers to
get out of their own way in selling spectrum did not actually enable the
providers* to get out of their own way in selling spectrum. It *should* be
easier

Your outcomes will vary depending on whether this is deployed for

It’s one of those things that makes a lot more sense on paper than in practice.
I’ve found it to be operationally difficult from the perspective the provider

Hi,
Alien wavelengths is a fairly old concept and more generally just
refers to running any wavelength over a DWDM system that isn't
generated by that system's own transponders.
These days it is more about leasing spectrum (Spectrum as a Service),
but that comes in several different flavours. Th

Actually, it's not empty. I know 2 operators in my part of the world that do it

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

Not related to who is using them really but..

I looked at this before and go far enough in the conversations with one carrier

customers they were no longer offering it. You are likely better off getting a
volume deal on waves, which can be had for pretty cheap these d
