Could Fiber Be The Next Big Bottleneck In Data Center Growth?
Data Center Knowledge, Thursday, September 3rd, 2026
Fiber availability is joining power and water as a hard constraint on where data centers can actually be built.
Fiber optic connectivity is emerging as a siting constraint on par with power and water availability.
Data center bandwidth demand rose roughly 330 percent in the early 2020s, driven by AI workloads that move enormous volumes between training and inference tiers.
Established tech hubs enjoy dense, competitive fiber routes, while emerging markets chasing data center investment often lack the connectivity to support it.
The article advises operators to weight fiber availability heavily during site selection, coordinate early with multiple carriers, and evaluate alternative connectivity paths offered through cloud providers such as AWS and Azure.
