Alien wavelength port density seems to be the issue with the 
DWDM vendors today. Most are reserving those ports for east-
west transport of the optical system itself, although a few 
are now "supporting" alien wavelengths.

The issue becomes worse if you don't own the infrastructure, 
as I'm yet to find a telco willing to bill you for an alien 
wavelength model.

For core link expansion in this case, it pays to have the 
best deal possible with the right optical kit.

Cheers,

Mark.
