Cross-border connectivity between Mexico and the US: an overview

Strategic fibre optic routes connecting Mexico to key U.S. hubs like McAllen, Texas and Eagle Pass are critical to this evolution, acting as gateways for high-capacity data flows serving everything from enterprise networks to hyperscale cloud operations.

One of the most notable developments is the partnership between Fermaca and Zayo, who are building robust new fibre routes across the U.S.-Mexico border. These projects mark a shift from legacy systems toward modern, high-capacity infrastructure capable of supporting the needs of hyperscalers and major cloud providers. Of particular significance is the construction of a new, neutral fibre network from Laredo to Texas - the first new cross-border network in Mexico in over 25 years. This is a landmark development, offering cutting-edge technology and open-access models that benefit carriers, content providers, and enterprise users alike.

However, 2025 is shaping up to be a difficult year for the sector. Operators that haven’t already laid the groundwork may find themselves entering a market full of turbulence due to factors like inflation, shifting regulations, and delays in permits. Despite the setbacks, these routes are vital not only for national connectivity but for broader North American digital integration. With the surge in data consumption, AI workloads, and cloud migration, hyperscalers are actively seeking more resilient, redundant, and diverse pathways—and Mexico is central to that strategy.
