Denis O'Brien has been named as the largest shareholder in a new company that aims to connect the Caribbean with fibre optic cabling.

Deep Blue Cable is planning to run underwater, high speed connections between Miami and a number of Caribbean countries, with the service ready to launch in 2020.

According to The Jamaican Gleaner newspaper, Mr O'Brien holds the largest stake in the company, which formally announced its plans earlier this month.

Mr O'Brien is also the founder and chairman of telecommunications company Digicel, which has operations in the Caribbean, Central America and the Pacific Islands, though the two companies are not connected.

Deep Blue Cable is hoping its cabling will serve as a replacement to some of the aging systems currently in place in the region, many of which are reaching the end of their life-cycle.

The company is also anticipating a massive increase in demand for high-speed connectivity in the next 20 years.

Its initial plans will see a 12,000km of cable laid to connect 12 countries. The cable will house eight fibre pairs, which will each have a potential top speed of 20 terrabytes per second.
