Nokia and MX Fiber have begun implementing a new optical transport backbone in southwest Mexico. The 1,800km infrastructure aims to provide ultra-high-capacity connectivity to one of the country’s most populated regions with less infrastructure coverage.
“We are very satisfied to work with Nokia to deploy a proven optical solution that offers great capacity and high-quality services at a lower operational cost,” says MX Fiber. “This infrastructure is fundamental to serve our clients and for the success of megaprojects like the Interoceanic Corridor of the Isthmus of Tehuantepec and the Mayan Train, which seek to trigger economic development in the region.”
The southwest region of Mexico has historically shown a deficit in telecommunications infrastructure compared to other areas of the country. However, a national strategy aims to foster growth in the area through two significant infrastructure initiatives: the Interoceanic Corridor of the Isthmus of Tehuantepec and the Mayan Train.
Nokia and MX Fiber aim to support the area’s development through the introduction of the Nokia 1830 Photonic Service Switch (PSS) solution. This platform is designed to support a wide range of services with speeds of 10G, 100G, 200G, and 400G per wavelength. This ensures robust initial capacity to meet the requirements of enterprise customers and other operators.
The infrastructure incorporates Dense Wavelength Division Multiplexing (DWDM) with Flex-Grid technology. This is a key component that allows MX Fiber to maximize fiber optic spectrum efficiency. This flexibility enables the dynamic allocation of bandwidth and the coexistence of multiple high-speed channels over a single fiber, which optimizes operational and expansion costs. The total network capacity is projected to scale up to 2.4 Tb/s.
The network’s design includes a seamless upgrade path to 400G and 800G technologies, ensuring the infrastructure’s long-term viability and competitiveness. For management and maintenance, the system integrates real-time monitoring tools using Optical Time Domain Reflectometry (OTDR). This functionality allows for the proactive detection and precise location of faults or degradations in the optical fiber. This in turn minimizes downtime and helps ensure high service reliability.
The network will connect strategic points such as data centers, industrial parks, and submarine transport nodes. Following this implementation, companies in sectors like manufacturing, logistics, tourism, and technology are expected to gain access to carrier-grade connectivity services. This is expected to help drive digital transformation, competitiveness, and the economic integration of southwest Mexico with national and international markets.
