Sure, if you build a network using bidirectional DWDM (both directions
over a single fiber, using different wavelengths), you could build
more wavelengths in one direction than in the other.
Even if you use unidirectional systems with multiple wavelengths for
the same path, you could save some equipment by using fewer lambdas in
the direction that has less traffic.
Provided that routers support link bundles that can include
unidirectional links, this shouldn't add much complexity.
