Norte Conectado (Infovia 04)

Norte Conectado (Infovia 04): what this cable is

Norte Conectado (Infovia 04) is a stretch of Brazil's Norte Conectado program that extends a subfluvial (riverbed) fiber backbone north, into the state of Roraima, one of the country's most isolated regions. The distinctive thing about Infovia 04 is its destination: Roraima has historically been cut off from Brazil's main infrastructure, and riverbed-and-terrestrial fiber along the Rio Branco gives the state a qualitatively new level of connectivity.

The route connects Vila de Moura (Amazonas state) with Boa Vista (the capital of Roraima), serving the municipalities of Santa Maria do Boiaçu, Caracaraí, Iracema, and Mucajaí. The stretch is delivered by the infrastructure administrator EAF.

Geography and route

Infovia 04 runs up the Rio Branco from Vila de Moura toward Boa Vista. According to the project, the EAF section consists of about 466 km of subfluvial cable along the Rio Branco bed and about 141 km of terrestrial segment, roughly 607 km in total. This combination of river and overland deployment is typical of an exit from the river network to a continental city.

Part of the Norte Conectado program

Infovia 04 is one of the stretches of the Norte Conectado program, planned in total for roughly 13,200 km of subfluvial fiber, more than 70 settlements, and about 7.5 million residents across six Amazon states. Sibling stretches, including the pilot Infovia 00 and the western Infovia 02, form a single northern-region backbone, to which Infovia 04 connects Roraima.

Technical specifications

• Type: subfluvial backbone (Rio Branco) plus a terrestrial segment.
• Route: Vila de Moura (Amazonas) to Boa Vista (Roraima).
• Length: about 607 km (approximately 466 km along the Rio Branco bed + 141 km terrestrial).
• Infrastructure owner: EAF; the stretch was delivered to the Ministry of Communications as part of the Norte Conectado rollout.

Why Infovia 04 matters: connectivity for isolated Roraima

The value of Infovia 04 is that it addresses one of the hardest-to-reach states. For Roraima this is basic resilience infrastructure:

• municipalities along the Rio Branco move from satellite to riverbed-and-terrestrial fiber, changing latency and capacity by an order of magnitude;
• Boa Vista and the towns along the route gain a basis for telehealth, education, government services, and business;
• a state historically dependent on external and satellite links is integrated into the national Norte Conectado network.

What is known and what is not yet disclosed

• Infovia 04 is a subfluvial-and-terrestrial stretch of Norte Conectado, Vila de Moura to Boa Vista, about 607 km;
• approximately 466 km along the Rio Branco bed + 141 km terrestrial; owner is EAF;
• it serves Santa Maria do Boiaçu, Caracaraí, Iracema, Mucajaí, and Boa Vista.

Not yet fully disclosed: exact full-commissioning dates for all segments, the split of capacity among operators, and a detailed map of the terrestrial segment.

Technically: what effect to expect

• Latency. For towns along the Rio Branco this means tens of milliseconds over a riverbed-and-terrestrial route instead of satellite delay.
• Capacity and sovereignty. Fiber removes satellite limits and reduces an isolated state's dependence on external links.
• Resilience. The combination of river and terrestrial segments gives Roraima an anchor, but demands attention to repair at the junction of the two environments and to the Rio Branco flood season.

Why this matters for GeoCables / monitoring weak points

Infovia 04 changes the availability map of an entire state, previously one of the most cut off in Brazil.

Before: Boa Vista / Rio Branco towns -> satellite / external links -> Internet After: Boa Vista / Rio Branco towns -> Infovia 04 (Rio Branco, subfluvial + terrestrial) -> Norte Conectado network / Brazil trunk -> Internet

For monitoring it is worth tracking latency dropping in Roraima as the stretch comes into service, the appearance of terrestrial BGP routes instead of satellite ones, resilience at the junction of the river and terrestrial segments, and correlation between outages and nodes falling back to backup links.

Short conclusion

Norte Conectado (Infovia 04) is a subfluvial-and-terrestrial backbone along the Rio Branco, connecting isolated Roraima and its capital Boa Vista to the unified Norte Conectado network. What is interesting here is not the length, but that one of Brazil's most cut-off states gains terrestrial fiber instead of dependence on satellite and external links.
