Yes, to get their speeds they used the usual wavelength division multiplexing, except over an insane 750 wavelength channels, space division multiplexing over the 38 corse with 3 modes, and 256 QAM with dual-polarization in each
For perspective, at work for our production network through Switzerland, we use at most 16 QAM with dual-polarization, and at most 88 channels. With just normal single mode one-core fibers. This paper has just everything blown up in all directions of cool.

Yeah… mhmm… right. I know some of these words!
