Submarine cables have been around far longer than some may realise and play an absolutely pivotal role in global data transfer systems. 

 The world’s first submarine cable was a telegraph cable laid in the 1850s which spanned the Atlantic Ocean. This first endeavour didn’t last all that long – as we would expect with our modern-day foresight – having been made from several copper cables wrapped in rubber, hemp and iron.

 It does go to show how far the submarine cable has come in more than 150 years and there is sure to be more development to come.
