The distinction between wavelength and strand is an important one. It is the crux of the matter. I mean bi-directional one angstrom lambda. You need two strands and multiple wavelengths to get the same from WDM. My analogy had to be stretched. The lanes could be fibers and colors in WDM, but there is only one lane, one strand and one color, in SR. "Echo cancellation" type problems are also critical issues. When you're mixing wavelengths in WDM for various purposes, you get pulse diffusion or broadening which decoheres the signal and forces you to down size throughput. Because of mixing, possibilities of higher harmonic sympathetic resonance interference occurs, which increases signal drag and collision probability. There is also increased fiber wall reflection interference from mixing. In the SR mode there are no collisions. It's Pure. So there is no need to cancel what doesn't occur. That may not be the case though upwards beyond OC-12,000. Ok photonics experts, you can start throwing rocks at my primitive applied physics knowledge.
