Subsea cables are critical infrastructures that support the digital world, yet they remain vulnerable to geopolitical tensions. These fiber optic cables, often compared to shipping lanes, are essential for global communication, transmitting vast amounts of data through highly purified glass and laser pulses. However, the production of these cables is concentrated among a few companies, creating a bottleneck that could impede technological advancements and infrastructure expansion. The shift from state-owned to private investor-led telecommunications infrastructure has transformed funding dynamics, leading to increased investment and innovation. However, the growing influence of big tech companies in owning transatlantic cables raises concerns about data privacy and security. This concentration of ownership affects internet access and highlights issues of data governance. Despite these challenges, the redundancy built into internet infrastructure ensures stability and reliability, akin to the natural monopoly seen in railroads.
