Virgin Media has announced it has enhanced its cabling between the UK mainland and Ireland.
According to the firm, the 40Gb submarine enhancement supports its plans for super-fast broadband roll-out across the UK.
Virgin Media's fibre cabling carried 10Gb channels across the Irish Sea, however the new infrastructure will be able to provide additional bandwidth.
The upgraded cable runs from Lytham St Anne's to Dublin and covers around 238km.
Peter Newcombe, leader of metro Ethernet sales at Nortel, the firm Virgin Media used to deploy the cabling, said the 40Gb solution upgraded the existing network "without extensive network re-engineering or massive recabling costs".
He added: "This was important on the Virgin Media project because their link is 238km long and most of it is undersea. It's also an advantage on the busy undersea routes to Ireland."
Virgin Media was recently forced to apologise after it mistakenly informed people in Whitchurch, Shropshire, they were able to get its 50Mb fibre-optic broadband service, reported the Whitchurch Herald.
