FROM THE DEEP SEA TO DESERT DUNES Reimagining Terrestrial Fiber Networks for the Age of AI and Hyperscale Data BY SAMIA BAHSOUN, HERVE FEVRIER, AND GIORGIO GRASSO
A NEW TERRESTRIAL FRONTIER
In the race to power the AI era, infrastructure is destiny. Generative AI, hyperscale data centers, and machine learning models are not just hungry for data —they are voracious. The exponential growth of AI workloads—projected to exceed 40% CAGR through 2030—demands high-capacity, low-latency, and ultra-reliable fiber backbones connecting clusters, clouds, and continents. Yet, today’s terrestrial infrastructure is faltering under the weight of that demand. The bottleneck lies not in the cable, but in how we power, amplify, and scale it across vast distances. The Aqua2Terra (A2T) initiative proposes an innovative and radical approach to terrestrial optical line systems — one that borrows its DNA from the most reliable systems on Earth: subsea cables. By repurposing the advances

of subsea repeaters for a land-based future and adapting subsea repeater design for buried, sealed manhole deployment, A2T offers an end-to-end powered, maintenance and regulation-light alternative to the conventional InLine Amplifier (ILA) model—purpose-built for the AI and hyperscale era as an agile, secure, and scalable alternative for high-capacity fiber deployments.
THE LEGACY BURDEN: FIBER NETWORKS UNFIT FOR PURPOSE
Traditional terrestrial fiber networks were designed as national mesh systems, interlacing cities and towns through dense grids of fiber routes and In-Line Amplifier (ILA) huts approximately every 80 kilometers. These networks were optimized for population proximity and national backbones, ensuring access and redundancy close
