Multinational telco Millicom has announced a strategic agreement with Trans Americas Fiber System to join the TAM-1 submarine cable system, a key infrastructure designed to strengthen digital connectivity in Central America and the Caribbean.

The long-term commercial agreement will enable the company to expand its international capacity through access to an open and neutral platform, designed to meet the growing demand for high-capacity digital services in the region.

The TAM-1 system is one of the most significant connectivity projects in the Americas. Spanning approximately 7,000km, this submarine fiber-optic cable will connect the United States to multiple points in Central America, the Caribbean, and South America, creating a more resilient and diversified network.

The infrastructure is designed to offer a minimum capacity of 18 Tbps per fiber pair, which will support the sustained growth in data traffic driven by cloud services, enterprise applications, and new digital technologies.

Additionally, the system is structured into two major segments - north and south - connecting various key markets, from Florida to countries such as Mexico, Guatemala, Honduras, Panama, and Colombia, thereby establishing a strategic hub for regional interconnection.

Through its participation in TAM-1, Millicom seeks to strengthen its network’s resilience, improve route redundancy, and increase the scalability of its infrastructure - critical factors for ensuring low-latency and high-availability services.

The company, which operates in the region under the Tigo brand, views this initiative as part of its digital infrastructure investment strategy, aimed at driving digital inclusion and economic development in the markets where it operates.

Millicom said that this integration will enable it to offer more robust solutions to operators, businesses, and public administrations in a context marked by rapidly growing demand for connectivity.

With its deployment scheduled for 2026, this system is shaping up to be a key component in the evolution of the Latin American digital ecosystem, strengthening international connectivity and laying the groundwork for the sector’s future growth.
