Arelion has launched a second fully diverse underground DWDM fiber route linking Querétaro and Monterrey, Mexico, strengthening connectivity for the country’s fast-growing AI and cloud markets. The new path, built on C+L band open optical line systems and 400G/800G coherent pluggable optics, extends Arelion’s Latin American AI superhighway with low-latency, high-availability services. It provides redundancy and additional capacity between Mexico’s top digital hubs, while also linking into cross-border routes via McAllen and Laredo, Texas.
The expansion targets Mexico’s accelerating data center market, with Querétaro already hosting 15% of the country’s facilities and nearly 95 MW of commissioned power. Industry forecasts project that number could rise to 700 MW as hyperscale players expand. Monterrey is also rapidly scaling capacity, positioning itself as a strategic tech hub close to the U.S. border. By reinforcing this corridor, Arelion supports nearshoring initiatives, cloud adoption, and emerging AI workloads such as edge inferencing.
Arelion now operates ten regional PoPs in Mexico across Querétaro, Monterrey, Mexico City, Guadalajara, Mérida, San Luis Potosí, and Tijuana. The company said its enhanced network footprint enables wholesale and enterprise customers to tap services including IP Transit, Wavelengths, 100G EVPL, and Cloud Connect. The new Querétaro-Monterrey route is scheduled to go live in early Q1 2026.
• Second fully diverse underground DWDM route between Querétaro and Monterrey
• Built with C+L band open optical line systems and 400G/800G coherent pluggables
• Expands Arelion’s AI superhighway across Latin America with links into Texas
• Querétaro hosts 15% of Mexico’s data centers, with power expected to reach 700 MW
• Ten Arelion PoPs now operating across Mexico, including major hyperscale facilities
“Mexico’s AI and cloud sectors are experiencing substantial growth, in turn driving strong demand for terabit-scale Waves and reliable IP services to support emerging applications,” said Edison De Leon, Regional Director of Latam & Caribbean at Arelion.
🌐 Analysis: Arelion’s investment reflects the sharp rise in demand for high-capacity, low-latency infrastructure in Mexico, where Querétaro and Monterrey are becoming key hyperscale hubs. This move parallels broader regional trends, as operators including Telxius and América Móvil scale subsea and terrestrial networks to meet AI and cloud workloads. By establishing redundant, fully underground routes, Arelion positions itself to serve both domestic markets and U.S.-Mexico cross-border traffic at a time when nearshoring and AI infrastructure are converging.
