> I strongly doubt there are any non-fiber submarine cables.
not for telecom, not anymore, but a number of submarine cable laying ships are equipped specifically for laying high voltage power cables to offshore wind farms. And for things like high voltage cables linking medium sized islands to a nearby mainland (eg: Vancouver Island, BC to the continent).
After submarine telecom, the biggest uses for such vessels are offshore power and the oil/gas industry.
