The Internet Crosses Oceans Inside Glass Cables

Your Wi-Fi connection is wireless. Much of the internet’s journey between continents is not. Explore the submarine fiber-optic cables that carry data across oceans as light. See how protective layers and repeaters support the connection, why routes are surveyed carefully, and how repair ships recover and splice damaged cable. Alternative routes can help keep traffic moving, but the impact of a break depends on the network and available capacity. Cable cutaways and scale are illustrative.
