Nokia and MX Fiber have launched a high-capacity optical transport backbone to expand gigabit connectivity across southeastern Mexico, targeting underserved states such as Chiapas, Tabasco, and Quintana Roo, with future reach into Campeche and Veracruz. The 1,800 km expansion leverages Nokia’s Flex-Grid DWDM technology and 1830 Photonic Service Switch (PSS) platform, enabling scalable 10G, 100G, and 200G services with an upgrade path to 400G and 800G.
Seven new DWDM routes will underpin major government-backed infrastructure projects, including the Interoceanic Corridor of the Isthmus of Tehuantepec and the Maya Train, both designed to stimulate economic growth, improve mobility, and enhance digital inclusion in the region. The network will support access to data centers, industrial parks, and subsea transport hubs, critical for commerce and cloud adoption.
MX Fiber operates under the infrastructure arm of MXT Holdings, a Mexican telecom infrastructure platform backed by institutional investors. Founded in 2015 with a focus on wireless tower sites, the company expanded into fiber management in 2017 and DAS systems in 2018. MX Fiber’s portfolio includes more than 3,500 km of metro and long-haul fiber, 1,450+ telecom towers, and multiple distributed antenna systems. Its network footprint spans much of Southeastern Mexico, where it connects urban hubs, industrial zones, and coastal transport gateways, positioning it as a key enabler of regional broadband and enterprise connectivity.
The Nokia 1830 PSS features dynamic network management, real-time monitoring via Optical Time-Domain Reflectometry (OTDR), and the ability to add capacity without service disruption. MX Fiber says the new backbone will provide the high-quality, cost-efficient connectivity needed for regional transformation.
• 1,800 km expansion across Southeastern Mexico
• Seven new DWDM routes to boost infrastructure and economic growth
• Support for 10G, 100G, 200G services, upgradeable to 400G/800G

• Built-in OTDR for real-time network monitoring and fault detection
“We are very happy to work with Nokia to deploy a proven, optical solution that delivers massive capacity and high-quality services at a lower operational cost,” said Nestor Bergero, CEO of MX Fiber. “This solution is crucial to supporting our customers and to the success of mega-projects such as the Interoceanic Corridor and Maya Train which are designed to spur economic development in the region.”
🌐 Why it Matters
Mexico’s southern states have long lagged behind in broadband penetration and economic opportunity. By combining DWDM scalability with strategic public infrastructure projects, MX Fiber and Nokia are enabling a leap forward in both digital inclusion and regional competitiveness. This deployment aligns with broader Latin American trends of leveraging transport fiber networks to bridge rural-urban connectivity gaps and support cloud, IoT, and mobility ecosystems.
