Aracajú, Brazil: Submarine Cable Landing Point

Aracajú is the capital of the state of Sergipe in northeastern Brazil, situated on the country's Atlantic coast approximately 350 kilometres north of Salvador. As a submarine cable landing point, Aracajú connects to Brazil's broader coastal cable network through one submarine cable. That cable, the Brazilian Festoon, runs entirely along the Brazilian coastline, linking Aracajú to other landing points within the same country rather than extending to international destinations.

The corridor enabled by the Brazilian Festoon is domestic in nature, forming part of an intra-national coastal ring that stitches together multiple Brazilian coastal cities. Aracajú's position along the northeastern stretch of this coastline places it between the denser cable hubs of Fortaleza to the north and Salvador to the south, giving the city a degree of connectivity within this domestic submarine infrastructure.

Cables Landing at Aracajú

The Brazilian Festoon is the sole submarine cable landing at Aracajú. With a total length of 2,552 kilometres, this cable reached ready-for-service status in 1996 and connects multiple landing points exclusively within Brazil. As a domestic coastal cable, all of its endpoints are located along the Brazilian seaboard. It was among the earliest submarine cable deployments in Brazil, with its 1996 RFS date coinciding with the earliest recorded submarine cable activity in the country.

Regional Context

Within Brazil's submarine cable landscape, Aracajú ranks among the smaller landing points by cable count. The country hosts 22 submarine cables across 64 landing points, with major hubs such as Fortaleza serving 10 cables and Rio de Janeiro serving 8. Aracajú, with its single cable, sits in the lower tier of Brazilian landing points alongside several other coastal cities that serve focused, single-cable roles rather than functioning as multi-cable international gateways.

Network Role

Aracajú functions as a single-cable terminus on the Brazilian Festoon, contributing one node to the domestic coastal submarine cable ring that runs along Brazil's Atlantic seaboard. Its role is oriented entirely toward intra-national connectivity, linking it to other Brazilian coastal communities rather than forming part of any intercontinental or regional international route.

Within the regional submarine cable graph, Aracajú represents one of many landing points that collectively distribute domestic coastal connectivity along a coastline otherwise dominated by a small number of high-density international hubs. The presence of even a single cable landing point in a northeastern state capital reflects the geographic reach of Brazil's coastal submarine infrastructure beyond its principal international gateway cities.
