• Nokia’s Flex-Grid DWDM and 1830 PSS technology brings scalable 10G/100G/200G capacity, with smooth upgrades to 400G and 800G, monitored dynamically via OTDR.
• The network underpins economic megaprojects and extends high-speed broadband to Chiapas, Tabasco, Quintana Roo—and soon Campeche and Veracruz.
What happened：Nokia delivers high-capacity optical backbone for MX Fiber
Nokia has completed a new ultra-high-capacity optical transport backbone for MX Fiber, marking a major milestone in improving connectivity across southeastern Mexico. This 1,800 km expansion employs Nokia’s Flex-Grid Dense Wavelength Division Multiplexing (DWDM) and the 1830 Photonic Service Switch (PSS), delivering scalable service options of 10G, 100G, and 200G—and notably allowing seamless future upgrades to 400G and 800G without interruption.
The network includes seven new DWDM routes, enhancing connectivity for entities across Chiapas, Tabasco, and Quintana Roo, with plans to reach Campeche and Veracruz shortly. Key users include data centres, industrial parks, subsea transport hubs, and vital national infrastructure projects such as the Interoceanic Corridor of the Isthmus of Tehuantepec and the Maya Train.
Dynamic network management and real-time performance monitoring via Optical Time-Domain Reflectometry (OTDR) ensure resilience, service assurance, and efficient operations. MX Fiber CEO Nestor Bergero emphasised lower operational costs and massive capacity delivery, while Nokia’s Javier Falcón hailed the deployment as a critical step toward digital inclusion and economic empowerment in the region.

Why it’s important
This project directly addresses the persistent digital divide in one of Mexico’s most populous but underserved regions, offering crucial infrastructure to support advanced government, commercial, and community demands. With scalable capacity up to 2.4 Tb/s, the new backbone lays the groundwork for transformative cloud services, enhanced data-intensive operations, and improved connectivity for public services, commerce, and mobility.
It arrives at a pivotal moment as the Interoceanic Corridor and Maya Train projects ramp up—both critical to regional economic revitalisation and integration. Their success hinges on robust digital infrastructure, which this network now enables. Moreover, the modular, future-ready design ensures long-term viability, allowing MX Fiber to stay ahead of demand without expensive overhauls.
