An AI data center can secure substantial electrical capacity, accommodate thousands of accelerator racks, and still encounter a serious infrastructure limitation when its network cannot move information between computing resources efficiently. Power determines how much computing equipment a facility can operate, while optical connectivity determines how effectively those resources can communicate across racks, halls, and separate buildings. A location with sufficient electrical capacity but limited underground fiber routes may struggle to accommodate the networking requirements of subsequent expansion phases. Consequently, site evaluations increasingly need to examine available fiber strands, conduit capacity, carrier diversity, and the physical routes connecting individual buildings. These considerations make telecommunications infrastructure an increasingly important component of AI site assessments, alongside electricity access, land availability, cooling capacity, and construction readiness, with its relative importance depending on the connectivity requirements and expansion plans of each development.
