Ilhéus, Brazil

Ilhéus: Submarine Cable Landing Point

Ilhéus is a coastal city in Brazil that serves as a landing point for submarine cable infrastructure along the country's Atlantic seaboard. A single submarine cable currently lands at Ilhéus, connecting it to the broader network of undersea communications links that run along the Brazilian coastline. That cable, the Brazilian Festoon, is a domestic system that links multiple points within Brazil, making Ilhéus part of a nationally oriented coastal corridor rather than an intercontinental routing hub.

The Brazilian Festoon, which reached ready-for-service status in 1996, traces a route along the Brazilian coast, and Ilhéus represents one node in that domestic cable arc. With a length of 2,552 kilometres, the system connects several Brazilian landing points to one another, providing intra-national submarine connectivity. Ilhéus therefore participates in a regional, coastal network designed to link Brazilian cities along the Atlantic littoral.

Cables Landing at Ilhéus

Brazilian Festoon is a 2,552-kilometre submarine cable system that reached ready-for-service status in 1996, currently listed with draft status. All landing points on this cable are located within Brazil, making it a wholly domestic coastal system. The cable runs along the Brazilian coastline, and Ilhéus is one of its Brazilian termination points, forming part of a chain of national landing sites connected by this submarine link.

Regional Context

Within Brazil, Ilhéus is a comparatively minor landing point when measured by the number of cables served. Fortaleza leads the country with ten cables, followed by Rio de Janeiro with eight, Santos with four, and Salvador with three. Afuá and Alenquer each host two cables, while Ilhéus hosts one, placing it at the lower end of Brazil's submarine cable landing hierarchy. Its closest geographic peer in cable count among the listed cities is the single-cable tier, though geographically it sits along the same stretch of Atlantic coastline as the more heavily connected landing point of Salvador.

Network Role

Ilhéus functions as a single-cable terminus in Brazil's submarine cable graph. Its sole connection, the Brazilian Festoon, links it exclusively to other domestic landing points within Brazil, meaning the city does not currently anchor any international submarine cable route. The cable it hosts is a coastal system, enabling intra-national connectivity along the Brazilian Atlantic seaboard rather than providing a gateway to other countries or continents.

Within the regional submarine cable graph, Ilhéus represents a domestic node that extends the reach of Brazilian coastal cable infrastructure to a part of the country's coastline that is otherwise underserved by submarine connectivity. Its single cable gives it a defined but limited role in the overall network of Brazilian landing points, distinguishing it from larger hubs such as Fortaleza and Rio de Janeiro that anchor both regional and international cable systems.
