Facebook and Nokia have demonstrated that submarine Internet cables can be made much more efficient. During a test the two companies were able to provide the 5500 kilometer Trans-Atlantic Internet cable with 2.5 times as much capacity.
According to a statement from the Finish network company it will be possible in the not so distant future to reach a speed of 32 terabit (4.000 gigabyte) per second for every optical fiber. In practice this means that a lot more data can be send around the world much faster. International social networks like Facebook and global video streaming platforms like Netflix will be able to benefit from this increase in capacity, allowing for more reliable and faster Internet connectivity.
Submarine cables are a key component of the worldwide Internet infrastructure. A relatively small number of cables that have been placed at the bottom of the oceans connect the continents with each other.
When continental connection points need to process high volumes of international traffic they can turn into bottlenecks, slowing down access to certain online services or making them unavailable entirely. This make a smooth transfer of data through international Internet cables essential, also when taking into account that the number of web users and the time people spend online is still growing every single day.
Nokia says that it expects that the new Internet cable technology will be rolled out within the next three years.
