alt Hacker News"Repeaters are included every 40-80 km to keep the signal strong."
Does it mean that there's a ton of repeaters under the sea? Where do they get the power from?

Along the same cable. Data cables usually carry power to some degree too, for their own use.
i believe they're simply powered by the electric conductors bundled with the cable
the extra interesting part i think is how they amplify the signal without having to decode it, just optically
