The initial segment of what will be the first underwater fiber-optic link to skirt the North Pole, connecting Japan and Europe, will light up in early 2023. This stretch, called Iris, will link Iceland to Ireland. In subsequent years, the Far North Fiber project will lay down a cable through the Northwest Passage, connecting Iceland to Greenland, then Canada, Alaska, and finally Japan. Far North Fiber will help increase the geographic diversity of the world’s fiber-optic network; currently, submarine cables are laid along a few well-trodden routes, leaving the network vulnerable to local hazards, like ship anchors, earthquakes, or fiber-eating sea monsters.
