Las Toninas is a coastal town in Buenos Aires Province on Argentina's Atlantic coast at coordinates 36.472530°S, 56.695491°W, approximately 320 km southeast of Buenos Aires city. For submarine cable infrastructure, Las Toninas is Argentina's principal international landing point: seven major submarine cables land here, making it the densest cable hub on the South Atlantic coast of South America. Cables landing at Las Toninas serve Argentina's connection to Brazil, Uruguay, the rest of South America, the Caribbean, the United States, and (via the new Firmina cable) directly to North America.
The concentration of cables at Las Toninas reflects geographic and infrastructure history: the site offers protected approach conditions and was selected as the Argentine landing for the historic 1995 Unisur cable. Subsequent operators built on the existing infrastructure, with each new cable joining the existing landing zone rather than developing alternative Argentine sites. This concentration provides operational efficiency but also means a major incident at the Las Toninas beach manholes would affect substantial Argentine international connectivity simultaneously.
South America-1 (SAm-1) is a 25,000 km submarine cable in service since 2001, owned by Telxius. From Las Toninas it reaches Brazil (Fortaleza, Rio, Salvador, Santos), Chile (Arica, Valparaíso), Colombia (Barranquilla), Dominican Republic (Punta Cana), Ecuador (Punta Carnero), Guatemala (two landings), Peru (Lurin, Mancora), and the United States (Boca Raton FL, San Juan PR). One of the largest South American cable systems by landing count.
South American Crossing (SAC) is a 20,000 km submarine cable in service since 2000, owned by Cirion Technologies and Sparkle. From Las Toninas it reaches Brazil, Chile, Colombia, Panama (two landings), Peru, Venezuela, and the US Virgin Islands (St. Croix). A complementary cable to SAm-1 with overlapping coverage providing operator diversity.
Firmina is a 14,517 km submarine cable scheduled for ready-for-service in 2026, owned by Google. From Las Toninas it will reach Brazil (Praia Grande), the United States (Myrtle Beach SC), and Uruguay (Punta del Este). Firmina is one of the longest-single-cable systems planned and represents Google's hyperscaler investment in dedicated South Atlantic capacity for AI training and CDN edge connectivity.
Malbec is a 2,880 km submarine cable in service since 2021, owned by Meta and V.tal. From Las Toninas it reaches Brazil (Porto Alegre, Praia Grande, Rio de Janeiro). Direct South Atlantic regional cable for Meta's South American CDN edge.
Tannat is a 2,000 km submarine cable in service since 2018, owned by Antel Uruguay and Google. From Las Toninas it reaches Maldonado (Uruguay) and Santos (Brazil). Triangulation with Tannat creates Uruguay-Argentina-Brazil cable mesh redundancy.
Bicentenario is a 250 km submarine cable in service since 2011, owned by Antel Uruguay and Telecom Argentina. Direct Las Toninas-Maldonado link.
Unisur is a 265 km submarine cable in service since 1995, owned by Antel Uruguay and Telxius. The oldest Las Toninas cable, providing the original Argentina-Uruguay direct fibre connection.
Las Toninas's seven cables provide exceptional South American connectivity redundancy. Multiple paths exist to Brazil (SAm-1, SAC, Firmina planned, Malbec, Tannat), Uruguay (Tannat, Bicentenario, Unisur — three cables to a single neighbour), Chile (SAm-1, SAC), Peru (SAm-1, SAC), and the United States (SAm-1 via PR, SAC via St. Croix, Firmina direct). The owner mix spans major Spanish-Latin American carrier Telxius, Italian operator Sparkle, hyperscalers Meta and Google, and Latin American national operators (Antel Uruguay, Telecom Argentina).
The three Uruguay cables (Tannat, Bicentenario, Unisur) reflect the dense connectivity between Argentina and Uruguay — a function of geographic proximity, integrated banking and trade, and Argentina's role as an internet gateway for some Uruguayan traffic. The 2026 Firmina deployment will significantly expand Argentine direct US connectivity, reducing the historic dependency on transit via Brazil to reach North American backbones.
The Las Toninas submarine cable landing sits at 36.472530°S, 56.695491°W (36°28'21"S, 56°41'44"W), on the Atlantic coast of Buenos Aires Province in Argentina. The Las Toninas beach is part of the Partido de la Costa, a stretch of seaside resort towns between San Clemente del Tuyu and Mar del Tuyu. The beach manhole infrastructure here serves multiple cable systems with shore-end conduits feeding into the inland fibre routes toward Buenos Aires.
Seven submarine cables land at Las Toninas: SAm-1 (RFS 2001), SAC (2000), Malbec (2021), Tannat (2018), Bicentenario (2011), Unisur (1995), with Firmina (planned RFS 2026) joining the cluster.
Las Toninas cable landing is at 36.472530°S, 56.695491°W (36°28'21"S, 56°41'44"W), on the Atlantic coast of Buenos Aires Province, Argentina.
Through Las Toninas's cables, Argentina reaches Brazil (multiple landings via SAm-1, SAC, Tannat, Malbec, planned Firmina), Uruguay (via Tannat, Bicentenario, Unisur, planned Firmina), Chile, Colombia, Dominican Republic, Ecuador, Guatemala, Peru, Panama, Venezuela, the US Virgin Islands and US mainland (planned via Firmina to Myrtle Beach SC).
The earliest Las Toninas landing in the GeoCables dataset is Unisur, in service since 1995. SAC followed in 2000 and SAm-1 in 2001, establishing Las Toninas as Argentina's principal international cable hub.
Las Toninas operators include Telxius (SAm-1, Unisur co-owner), Cirion Technologies and Sparkle (SAC), Google (Firmina, Tannat co-owner), Meta and V.tal (Malbec), and Antel Uruguay (co-owner of Tannat, Bicentenario, Unisur), and Telecom Argentina (Bicentenario co-owner).
