São Sebastião da Boa Vista, Brazil

São Sebastião da Boa Vista: Submarine Cable Landing Point

São Sebastião da Boa Vista is a municipality in the state of Pará, Brazil, situated within the Marajó mesoregion and the microregion of Furos de Breves. As a coastal locality in northern Brazil, it serves as a submarine cable landing point, connecting it to the broader national digital infrastructure that spans Brazil's extensive coastline and inland waterways. One submarine cable lands here, providing a direct link to the country's domestic connectivity network.

The single cable landing at São Sebastião da Boa Vista is Norte Conectado (Infovia 03), a domestic system that runs entirely within Brazil. With a length of 600 kilometres, this cable is considerably shorter than the Brazilian average of approximately 4,840 kilometres across the country's submarine cable systems, reflecting its role as a targeted regional connector rather than a long-haul international link. Its scheduled ready-for-service date of 2025, currently in draft status, positions São Sebastião da Boa Vista as an emerging node in Brazil's evolving submarine network.

Cables Landing at São Sebastião da Boa Vista

Norte Conectado (Infovia 03) is a 600-kilometre submarine cable system with a projected RFS date of 2025, currently at draft stage. The cable connects points entirely within Brazil, making it a domestic intra-national system. São Sebastião da Boa Vista is one of its Brazilian landing points, and the cable does not extend to any other country. Its relatively compact length suggests it serves to bridge specific communities or regions within northern Brazil, consistent with the connectivity challenges characteristic of the Amazon and Marajó island geography.

Regional Context

Within Brazil's network of 64 submarine cable landing points, São Sebastião da Boa Vista hosts one cable, placing it among the smaller landing points in the country. Major Brazilian hubs such as Fortaleza (10 cables), Rio de Janeiro (8 cables), and Santos (5 cables) handle substantially greater cable volumes, while São Sebastião da Boa Vista is comparable to single-cable landing points elsewhere across Brazil's extensive coastline. It ranks within the top 81 percent of landing points in Brazil by cable count, reflecting the wide distribution of smaller, regionally focused cable termini across the country.

Network Role

São Sebastião da Boa Vista functions as a single-cable terminus within Brazil's domestic submarine cable infrastructure. The Norte Conectado (Infovia 03) system, landing here ahead of its 2025 RFS date, enables connectivity within the northern Brazilian corridor, a region where overland infrastructure can be constrained by the Amazon basin's geography. The landing point does not currently support international cable routes, positioning it as a contributor to domestic rather than intercontinental connectivity.

As Brazil continues to expand submarine cable coverage across its 64 landing points, the addition of São Sebastião da Boa Vista to the national network illustrates the country's effort to extend fibre-based connectivity to municipalities beyond the major southeastern and northeastern coastal hubs. In the regional submarine cable graph, this landing point represents one node in the effort to reduce connectivity gaps across Brazil's northern coastal communities.
