Super Highways

euNetworks is addressing the demand for more fibre connectivity between cities and data centres across Europe with Super Highways – new state-of-the-art high-capacity long haul fibre networks.

  • Strategically located and interconnected with key European cities.
  • Leveraging the latest fibre technology to innovate and re-imagine long haul network design.
  • Delivering high performance fibre connectivity, with substantial capacity to meet future high-bandwidth demands from content delivery, high powered compute, data processing and AI model training.

Super Highways combine seamlessly with our fibre-based metro networks and our extensive European footprint connecting data centres.

Key features

Strategically located and interconnected

Built to meet Europe’s critical demand for bandwidth 

  • Focused on the routes and regions where traffic and demand is highest – today that spans connections between Frankfurt, London, Amsterdam, Paris and Dublin (FLAP-D).
  • Super Highways are unique, direct long haul routes that avoid common capacity bottlenecks and existing areas of congestion.
  • Pathways between cities are as direct as possible, offering the shortest distances to achieve the lowest latency for our customers.
  • Route approaches to cities are unique, and our 18 metro networks across Europe offer multiple entry points to avoid existing congestion and deliver direct access to data centres in key areas.

New, modern fibre

Using the latest fibre technology for optimised performance

Super Highways are built with modern fibre types that deliver key performance advantages over existing legacy fibre systems.

Improved photonic performance

  • Super Highways use modern low-loss fibre types that deliver low attenuation, typically a measured loss of 0.20db/km, improving end-to-end photonic performance (OSNR). 
  • Superior bend insensitivity that reduces flaps.
  • Improved transponder performance that contributes to lower power draw and a more efficient carbon footprint.

High capacity

  • Super Highways are designed to meet bandwidth demand for years to come. We build with high fibre count cable and use fibre with a high bandwidth capacity per pair. 
  • This means that Super Highways have unconstrained fibre capacity and maximise how much bandwidth can be utilised in every fibre.

Flexible fibre compatibility

  • Super Highways cross seas, travel land distances of thousands of kilometres, and connect to metro networks in cities along the way. 
  • Our fibre choices have the best characteristics for each terrain and environment, and are fully compatible with each other.
  • This delivers consistently stable end-to-end performance and low attenuation across the entire system.

Optimised amplification facilities

Re-imagining long haul network design

The number of amplification sites on a long haul route and the standard of construction used for those sites has a direct impact on reliability, stability and power efficiency.

Optimised ILA spacing

  • The fibre types used on Super Highways deliver low attenuation, enabling wider distances between amplification sites without loss of performance.
  • This means Super Highways require fewer sites compared to other routes in service, which means less construction, fewer resources in delivery and more efficient performance in operation.

Highly efficient power consumption

  • Amplification sites on Super Highways are built with modern cooling equipment that uses highly efficient air conditioning, constantly monitoring and adjusting air draw to use less power when cooling. 
  • This reduces long-run power demands and makes Super Highways energy efficient.

Newly built infrastructure

  • Amplification sites on Super Highways are newly built network infrastructure, using joints, racks and connectors with the latest specifications and long-term service life. 
  • This delivers high reliability and service stability compared to legacy network infrastructure that has been in service for decades – they’ve been subject to years of repeated maintenance and environmental degradation, making them more susceptible to service outages, flaps and disruption today.
  • Super Highway amplification sites are a containerised, modular design that is scalable, secure and includes backup power supplies for resilience.
  • euNetworks own and operate the amplification sites on Super Highways. That means we control access to, and the maintenance of this critical fibre infrastructure.

Lower carbon impact

Sustainably designed for an optimised carbon footprint

  • Super Highways are designed and built with sustainability in mind. A reduced number of amplification sites in construction and in service means Super Highways use less resources and emit less carbon emissions when being built and when being used, reducing carbon impact. 
  • The sites that are built are optimised for power efficiency, reducing power consumption in service. 
  • Our innovative Network Construction Carbon Tool calculates project level carbon emissions. This allows us to fully understand, manage and accurately report on the environmental impact of Super Highways.
  • Our Carbon by Service Tool allows customers to report on the environmental impacts of their network services, especially Scope 3 emissions – those from the upstream or downstream supply chain – specifically the network connections owned and managed by euNetworks.
