The Curie submarine cable system is a four-fibre-pair and 10,500km cable connecting Los Angeles, California, and Valparaiso, Chile, with a branching unit to Panama City, Panama.

The Curie cable system is designed with 18Tbps per fiber pair and a total system design capacity of 72 Tbps.

Named after physicist and chemist Marie Curie, the Curie cable system will make Google the first major non-telecom company to build a private intercontinental cable. Google claims it will be the first new cable to land in Chile in almost 20 years, and will become the largest single data pipe connecting the country.

In the US, Curie cable terminates at Equinix LA4 data center and cable landing station, where hosts another submarine cable invested by Google, PLCN.

In Chile, Curie cable lands at CenturyLink Cable Landing Station at Subida Leopoldo Carvallo 350, Valparaíso, and connects to Quilicura Google Data Center in Santiago, Chile. 

In Panama, Sparkle lands the cable at its Panama Digital Gateway, the first green data center in Panama, as Sparkle acquires one fiber pair on the Curie cable system.

The Curie cable system is supplied by TE SubCom. The Curie cable system was ready for service on November 15, 2019.
