Brazil has long been a leader in the subsea cable market, with approximately 17 international cables landing on its shores. As our contribution lays out, there is a need for more transparency and accountability measures in subsea cable governance. For these reasons, the submission focuses on three key areas:Adopting transparency requirements for subsea cables governanceWhile new subsea cables do bring more capacity to the network, this does not automatically translate to more connectivity for internet users. We also propose technical interoperability requirements as a means of prompting a competitive subsea cable market in Brazil. Facilitating interconnectivity between subsea cable infrastructure and the national connectivity ecosystemInternational infrastructure expansion should be accompanied by regulatory instruments that facilitate interconnection with a diverse connectivity ecosystem.
