Isn't optical just as much about the end points as the cables?
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
Yeah... mhmm... right. I know some of these words!
For perspective, at work for our production network through Switzerland, we use at most 16 QAM with dual-polarization, and at most 88 channels (except we never utilize more than maybe 10). With just normal single mode single core fibers. This paper has just everything blown up in all directions of cool.
