The Submarine Cable Boom as Told by a Decade of TeleGeography Maps

TeleGeography: “There’s been lots of conversation about the recent boom in submarine cable construction. This flurry of activity becomes clearer when our annual map is viewed over time. Today, we’re putting several years’ worth of maps back-to-back to visualize an evolving undersea network. (And to reminisce about some of our favorite designs, if I’m being honest.) Give each map a click for a larger interactive view…Years ago, our map detailed 232 lit cables and 12 that were anticipated to come online before 2014. The final design charted submarine cable history, chronicling network latency and submarine cable capacity…This futuristic, high-contrast 2025 design depicts 597 cable systems and 1,712 landings. For those keeping score, that’s 38 more cable systems and 76 more landings than the 2024 edition. At the bottom of this map, we zero in on Networks of the Future with potential capacity, used capacity, and cable deployment stats for six major submarine cable routes: Trans-Pacific, U.S.–Latin America, Trans-Atlantic, Europe–Sub-Saharan Africa, Europe–Asia via Egypt, and Intra-Asia…”
