Alenquer, Brazil

Alenquer: A Quiet Node in Brazil's Submarine Cable Network

Alenquer, a municipality in the state of Pará in northern Brazil, may not be a household name in global connectivity, but it plays a modest role in the country's growing digital infrastructure. Nestled on the northern bank of the Amazon River, across from the larger city of Santarém, Alenquer is one of the landing points for the Norte Conectado (Infovia 00) submarine cable, a domestic network that stitches together the vast Amazon region.

The Norte Conectado Cable: Connecting the Amazon

The Norte Conectado cable, which became operational in 2022, spans 830 km and exclusively serves Brazil. Its purpose is to improve connectivity in the Amazon Basin, a region where reliable internet access has historically been a challenge due to its remote geography and dense rainforest. This cable connects five landing points: Alenquer, Almeirim, Macapá, Monte Alegre, and Santarém. Together, these points form a chain that links smaller towns to regional hubs, providing critical infrastructure for local networks to connect to broader national systems. Alenquer's position in this chain is particularly notable because it contrasts sharply with Brazil's major coastal landing points. Cities like Fortaleza, Rio de Janeiro, and Santos host multiple international cables that serve as gateways to global networks. In contrast, Alenquer is part of a domestic network focused on regional connectivity rather than international data traffic. This distinction highlights the Norte Conectado cable's role in addressing local needs, such as connecting schools, hospitals, and government offices in underserved areas.

Latency Insights: A Window into Performance

GeoCables' own latency measurements reveal intriguing details about Alenquer's connectivity. Across 12 completed checks from 11 source cities, the average round-trip latency to this landing point is 236 ms, with the best observed latency being an impressive 17 ms. These figures suggest that while Alenquer is not a major hub, its connection is robust enough to support essential services and local internet traffic efficiently.

Regional Context: A Small Player in a Big Network

Brazil is home to 22 submarine cables landing at 64 points along its coastline and inland waterways. The average cable length is 4862 km, reflecting the country's extensive international connections. Alenquer, with its single cable, ranks in the top 81% of Brazil's 74 landing points by cable count-a modest but important contribution to the nation's infrastructure. Unlike coastal giants such as Fortaleza, which hosts 10 cables, or Rio de Janeiro with 8, Alenquer's role is more localized, serving as a link in the Norte Conectado chain rather than a global gateway.

Alenquer's Role in the Amazon

Though Alenquer is not an industrial or technological powerhouse, its inclusion in the Norte Conectado network underscores the importance of connectivity in the Amazon region. The cable landing here ensures that even smaller municipalities like Alenquer can access the digital tools needed for education, healthcare, and governance. By linking these towns to larger hubs like Santarém and Macapá, the Norte Conectado cable helps bridge the digital divide in one of Brazil's most remote areas. Alenquer's story is one of quiet significance-a reminder that while major cities dominate the headlines in global connectivity, smaller towns like this are essential in building a truly inclusive digital network.
