Hello guys.
Long-distance telecommunications services (telephony and Internet) passed over the transocenânicos cable infrastructure (submarines) that cross the oceans linking the continents. Another option used for this purpose is the technology of space satellites, but this option is only a small portion of the intercontinental traffic because in addition to very expensive, has high latency (signal delay) and is unavailable when affected by natural interference, such solar storms.
The first transoceanic cables were capable of only about 40,000 simultaneous phone conversations, while modern fiber optic submarine cables have the capacity to millions of telephone circuits. In Brazil there are submarine cable linking the country to several South American neighbors, the United States, Africa and Europe (figure).
The Atlantis-2 cost 370 000 000 (million) and is the only submarine cable that directly connects South America to Europe, having length of 12,000 km and capacity of 40 Gbps. It belongs to an international consortium of 25 of the world's largest telecommunications operators, and 70% of the project was made by operators: Embratel, Deutsche Telecom, Telecom Italia, France Telecom and Telefonica Spain.

The optical cable and amplifiers used in subsea systems are designed to withstand water pressure of up to 8,000m (8 km) deep, i.e., 800 atm. The cable is extremely reinforced with high strength and reliability components (figure below) to ensure an average lifespan of 25 years.

The submarine cable is virtually parked in the seabed, due to the own weight of the cable and the weight of amplifiers - around 500 kg each. The expectation is that by 2016 we will have new transoceanic cables, and the two most important will connect the country to the capital of Angola (Luanda) and the other to Europe.

I take this discussion to share the link below that brings an interactive and updated map of submarine cables that connect continents.
