Porto Seguro, Brazil: Submarine Cable Landing Point

Porto Seguro is a city located on the far southern coast of the state of Bahia, in Brazil. Positioned along the Atlantic shoreline, it serves as a submarine cable landing point and is home to one submarine cable connection. That cable, the Brazilian Festoon, links Porto Seguro to other coastal landing points within Brazil, forming part of the country's domestic coastal cable infrastructure.

The single cable landing at Porto Seguro operates within an entirely domestic corridor, connecting Brazilian cities along the country's extensive Atlantic coastline. This makes Porto Seguro a point on a regional, intra-national submarine network rather than a gateway for intercontinental connectivity.

Cables Landing at Porto Seguro

Brazilian Festoon is the sole submarine cable landing at Porto Seguro. Spanning 2,552 kilometres, it reached ready-for-service (RFS) status in 1996 and carries a draft designation. The cable connects multiple landing points entirely within Brazil, making it a domestic coastal system. As the country's first submarine cable to reach RFS in 1996, the Brazilian Festoon represents the beginning of Brazil's submarine cable era.

Regional Context

Among Brazil's submarine cable landing points, Porto Seguro hosts one cable, placing it alongside smaller landing points such as Salvador and Praia Grande, which serve three cables each, and well behind the country's leading hubs of Fortaleza (10 cables) and Rio de Janeiro (8 cables). With one cable, Porto Seguro ranks within the top 81 percent of Brazil's 74 landing points by cable count, reflecting its role as a more modest node within a national network that spans 22 submarine cables across 64 landing points.

Network Role

Porto Seguro functions as a single-cable terminus on the Brazilian Festoon system, contributing to the domestic coastal connectivity that the festoon-style cable architecture provides along Brazil's Atlantic seaboard. Its role is specifically intra-national: the cable it hosts does not extend beyond Brazilian territory, meaning Porto Seguro participates in regional traffic distribution among Brazilian coastal cities rather than in international data exchange.

In the broader submarine cable graph of Brazil, Porto Seguro represents one of many smaller landing points that collectively extend the reach of coastal cable systems beyond the major hub cities, ensuring that segments of the Brazilian coastline — including the southern Bahia region — have a direct presence in the country's submarine cable network.
