Undersea Cable That Changed the World Is Surfacing

We live in a digital world, but its foundation is surprisingly physical: massive undersea cables. Jane Ruffino’s story at Wired offers a captivating look at the quiet retirement of TAT-8, the first fiber-optic line to cross the Atlantic—a system that transformed “phone cables” into the backbone of today’s global internet. Launched in 1988 and decommissioned in 2002, TAT-8 carried communications through historic events like the fall of the Berlin Wall, the rise of the web, and the birth of social networks. Today, a specialized crew aboard the MV Maasvliet is carefully removing the aging cable from the seabed so its steel, copper, and plastic can be recycled, making room for new, higher-capacity lines.

Ruffino uses the salvage operation to challenge enduring myths about undersea cables—yes, including tales of shark attacks—and to highlight the small but essential workforce that builds, maintains, and now dismantles the infrastructure. “Fiber-optic transmission is a near-magical way of carrying information by pulses of light,” she writes. “Most people don’t even think about how quickly we’ve come to expect instantaneous communication, even those of us who remember when an international call had to be booked in advance.”

This connectivity exists thanks to the daily efforts of a few thousand people, whether at sea or navigating permits, surveys, and logistics for thousands of kilometers of cables. These lines join millions of kilometers already lying on the ocean floor, ensuring our planet is constantly enveloped in pulses of light. Ruffino’s story also casts doubt on the idea that satellites will ever fully replace these undersea arteries.
