7 Subsea cable facts you probably don't know

From the deepest subsea cable to the very first transatlantic communications cable in the 1850's, we have 7 very different facts in this weeks blog...

7 Subsea cable facts you probably don't know

1. For all the talk about the 'cloud', practically all of the data shooting around the world actually relies on a series of undersea cables (most of them the width of a garden hose) to get around, a massive system of fibre-optic cables lying deep underneath our oceans. (source The Independent).

2. As of early 2017 there are approximately 428 subsea cables in service around the world spanning over 1.1 million kilometres, carrying power and transmitting data from continent to continent. (source Telegeography).

3. The first transatlantic communications cable was completed in the summer of 1858, running under the ocean between Ireland and Newfoundland. That cable took four years to build and lasted for less than a month. It took another six years before another line was set up so telegraph messages could cross the Atlantic again. (source The Independent).

4. Marine mammals and fish - Records extending from 1877 to 1955 reveal that 16 faults in submarine telegraph cables were caused by whales (Heezen, 1957; Heezen and Johnson, 1969). Thirteen of the faults were attributed to sperm whales, which were identified from their remains entwined in the cables. The remaining faults were caused by a humpback, killer and an unknown whale species. (source ICPC).

5. The deepest part of the submarine cable between Japan and the U.S. is about 8,000 meters below sea level (in the Japan Trench). That's almost as deep as Mount Everest is high! (source NEC).

6. Did you know around 70% to 80% of insurance pay-outs for wind farms relate to cable damage. And as the drive for more wind capacity increases, so does the possibility of more incidents of damage, potentially resulting in high value insurable claims. (source Allianz).

7. To date, Antarctica is the only continent not wired to the Internet via submarine cables. Due to a sparse population and ice shelf movement up to 10 meters/year, it is a very challenging environment.
