AI drives subsea and terrestrial network upgrades for hyperscale data centers

By PulseAugur Editorial · [1 sources] ·

The increasing demand for AI services is reshaping global network infrastructure, particularly subsea and terrestrial fiber optic networks. Hyperscale cloud and AI providers are now directly funding and deploying subsea cables to connect their data centers, moving away from traditional telecommunications-driven models. This shift necessitates higher capacity at cable landing stations and across backhaul networks, leading to the adoption of technologies like spatial-division-multiplexing (SDM) and 800G coherent pluggable optics to optimize space, power, and cost.
