The Arimao submarine cable system is a 2500km subsea cable to connect Cuba and Martinique.

The Arimao submarine cable system is deployed by ETECSA, the state-owned telecommunications monopoly in Cuba, and ORANGE, through its subsidiary Orange Marine, supplied by Alcatel Submarine Networks (ASN).

ETECSA and Orange have signed an agreement on the Arimao project in December 2022. And the system is expected to be ready for service by 2023. 

Upon completion, the Arimao submarine cable system will provide Cuba with a new route for international services, geographically diversifying the current connectivity. 

Prior to the Arimao project, ETECSA tried to land ARCOS-1 cable system in Cojimar, Cuba, but it was blocked by the United States in November 2022.

There is now only one international subsea cable connection to Cuba, the ALBA-1 cable system connecting Venezuela and Jamaica with Cuba.
