The ALBA-1 cable system is currenlty the only one commerical international cable system connecting Cuba to the world. Beside, there are GTMO-1 and GTMO-PR submarine cable systems landing at U.S. Naval Station Guantanamo Bay, Cuba, not available for commercial use. And the ARCOS-1 Cuba Extension is still pending.
The Siboney Beach CLS is the terminal station for the ALBA-1 cable system, the first international submarine cable system in Cuba, connecting Venezuela and Jamaica, activated in early 2013.
The ALBA-1 cable system is owned and operated by Telecomunicaciones Gran Caribe (TGC) which is 60% owned by state-run Telecom Venezuela and 40% held by Cuba’s Telco Transbit.
The Guantanamo Bay CLS (GTMO CLS) is located at the Defense Information System Network (DISN) Facilities at U.S. Naval Station Guantanamo Bay, Cuba (GTMO).
The Cojimar CLS is an existing facility owned by Empresa de Telecomunicaciones de Cuba S.A. (ETECSA), located at N23˚9’ 44.98’’，82˚18’ 45.97’’W, as the cable landing station for ARCOS-1 Cuba Extension.
A U.S. law prohibiting doing business with Cuba following the Cuban Revolution in 1959 prevented any U.S.-Cuban cable building. Finally in 2016, the U.S. Federal Communications Commission (FCC) dropped the last legal restrictions for a direct U.S.-Cuba cable.
In 2018, ARCOS-1 USA filed the FCC an application to add a branch to Cuba and a cable landing station in Cojimar, Cuba. The ARCOS-1 Cuba Extension will consist of two fiber pairs and will have an initial capacity of 100Gbps and planned capacity of 1.6 Tbps.
The ARCOS-1 Cuba Extension has not been activated yet.
There are now three international submarine cable system connecting Peru, i.e., Pan-America, South American Crossing (SAC), and SAm-1. A new cable system Pacific Cable connecting Peru to Chile and the United State is going to be ready for service soon in 2020.
Lurín is the international telecommunications gateway to Peru. All the above four submarine cable systems land in Lurin. Additionally, SAm-1 has a cable landing station in Mancora.
