Super Highway - Dublin to London including subsea cable Rockabill

Delivering over 1,000 km of state-of-the-art critical fibre infrastructure across the UK and Ireland, including the 224 km Rockabill subsea cable. 

This Super Highway’s unique routing, new amplification stations, and new ultra low-loss fibre provides a modern alternative to other fibre systems in the region.

Key features

  • Going live in 2019, our Rockabill subsea network is one of the newest subsea systems in the North Irish sea.
  • Best in class low-loss fibre types deliver consistent, high performance in both the terrestrial and subsea sections.
  • All amplification sites are newly built and designed with sustainability in mind. The ILA and cable landing sites (CLS) sites are built with highly efficient, modern cooling equipment that significantly reduces long-run power demands. 
  • This enables a much lower power consumption per bit and an optimised lower carbon footprint, delivering greater efficiency benefits to our customers.
  • With unique route options from Manchester to London, including diversity that connects to data centres in Leeds, or bypasses it entirely to avoid regional congestion and other routes in the area.
  • Our Central London bypass allows Dublin to Amsterdam connectivity avoiding London congestion.

Deploying new network infrastructure at pace

This Super Highway was rapidly delivered in a 9 month construction, serving customers from November 2019.

  • Over 1,000 kilometres of high fibre count cable
  • 340 new chambers and 239 new fibre joints 
  • 2 new cable landing stations 
  • 4 new ILA/PoP sites

Just as impressive as the rapid physical construction of this Super Highway was the management and timing of its logistical and administrative elements.

From the bureaucratic requirements of multiple countries, governments, local authorities and permitting authorities, to organising the specialist vessels and equipment required for a subsea and terrestrial system.

This delivery combined the experience of our project management team with our community of expert construction partners to deliver a new state-of-the-art fibre system in 9 months.

An innovative subsea cable burial that delivers unique benefits

Our subsea cable Scylla was laid using micro-routing – following sand wave contours on the sea bed to provide a deeper, more secure burial that naturally increases over time.

Re-imagining long haul network design

Our Super Highways aren’t constrained by the limitations of legacy fibre types. This gives us the ability to re-think how a long haul route is best designed.
