We sell some wavelengths on passive CWDM/DWDM path's between Datacentres
(less than 80Km) to customers to spread the cost of leasing the dark fibre.
But yes, as far as long distance (apart from bespoke offerings) I'm yet to
see a productised alien wave service. If you are spending all that money on
OTN kit the extra cost of the transponders is not really significant I
suppose.

I have yet to find a service provider that is actually willing to sell this
even when they have it in their service offering catalog.  The difficulties
of coordinating everything with the customer are so extreme that it seems to
usually make sense to either lease the customer dark fiber or capitalize the
transponders needed to carry it as a managed wave on the provider's
transport system.  Might make sense if you literally want half the spectrum
on a long-haul span or something.
