The evolution of submarine cables over 40 years

Since the deployment of the first optical fiber submarine cable, TAT-8, 38 years ago, the landscape of global connectivity has radically changed. This cable, connecting the United States, France, and the United Kingdom, marked the beginning of the fiber optic era, replacing old copper and telegraph connections. Today, the map of submarine cables is constantly expanding to meet the growing data demands of the modern world.

Why it matters

The evolution of submarine cables not only represents a technological advancement but also reflects geopolitical tensions and the influence of major tech corporations on Internet infrastructure. As connectivity needs increase, the construction of new cables becomes a strategic issue for countries and companies alike.

What we know

Current submarine cables can support data capacities vastly superior to those offered by TAT-8, allowing for faster and more efficient communication globally. Additionally, many of these cables are owned by tech giants seeking to secure their data infrastructure.

What remains unclear

Despite the advancements, questions remain about how new submarine cable routes will be managed and how geopolitical conflicts that may arise as they expand will be addressed. The company has not detailed how it plans to balance connectivity demands with these tensions.
