Hmm... What exactly are you transmitting in such a scenario? What's the physical layer protocol? I.e. what are the wires made of and what flows through them?

- fluoridation 2y agoWell, fair enough I suppose. Although a superficial reading would suggest this sort of technology is at least fifty years away from being deployable at opposite ends of a submarine cable to double the capacity without doubling the cable-laying. It reads like it's in the very early experimental stage, where they're barely demonstrating the plausibility, let alone the viability.

- fluoridation 2y agoThe "although" wasn't meant to invalidate it as an example, it was a link between two separate ideas.
