Brazilian digital infrastructure and data centre group V.tal has announced plans for a new subsea cable system linking Brazil and the US, while its subsidiary Tecto Data Centers revealed separate plans to build a new data centre in Porto Alegre.
Plans for the new cable system, “Synapse”, were revealed by V.tal at the PTC ’25 conference in Honolulu this week. According to a LinkedIn post from V.tal on Wednesday, the 9,700 km Synapse cable will run from New Jersey in the US to São Paulo.
V.tal said the Synapse system will be designed with space division multiplexing (SDM) technology and an open cable architecture, with 16 fibre pairs to support accelerating demand for AI, cloud and hyperscale international traffic.
The system will also include a branching unit to Fortaleza that will interconnect directly with Tecto’s 20MW TFOR3 data centre (a.k.a. “Mega Lobster”), which was officially launched in October 2025 with an initial IT load capacity of 4MW.
“By integrating subsea, terrestrial and data centre infrastructure, we are building a robust, scalable platform ready to support the growth of the global digital economy,” said V.tal CEO Felipe Campos in a statement.
V.tal said the Synapse cable is slated to be ready for service somewhere between 2029 and 2030.
Tecto’s new US$37.8m data centre in Porto Alegre
Meanwhile, Tecto announced the same day that it will invest around R$200 million (US$37.8 million) to develop a new data centre in Porto Alegre in the southernmost Brazilian state of Rio Grande do Sul.
The new data centre, TPOA1, is expected to commence operations in the fourth quarter of this year with 3 MW of initial capacity, which will gradually be expanded to 20MW in subsequent phases.
TPOA1 will be connected directly to the Malbec subsea cable, which is co-owned by Meta and GlobeNet and currently links Rio de Janeiro and São Paulo to Buenos Aires, Argentina.
Meta and V.tal struck a deal in May 2025 to build a new 280-km branch connecting the Malbec cable to Porto Alegre that’s scheduled to be completed in 2027.
Tecto said the new TPOA1 facility will be air-cooled and run on 100% renewable energy, serving big tech companies, digital content firms, cloud providers, and enterprise market clients as it expands the supply of digital infrastructure in southern Brazil.
