Our Cables

Altibox Carrier owns and operates one of Norway’s largest fibre-optic networks, extending across 30,000+ kilometers and connecting more than a million homes, businesses and data centers. Our cable system opens a new digital highway to and from the Nordics, with transport speeds of up to 800G and with 18 to 48 terabytes of capacity per fibre pair. 

Altibox’s two wholly owned subsea cables that stretch between Stavanger and Oslo in Norway and Newcastle in the UK (the NOUK cable), and from Larvik in Norway to Hamburg in Germany (the Skogenfiber cable). The Altibox carrier network, including its large metro network in Oslo, connects major sites across Northern Europe (including Hamburg, Frankfurt, Amsterdam, Brussels, London and Dublin), with super-fast connectivity to the Americas via the Havfrue (AEC-2) trans-Atlantic subsea cable.   

NO–UK cable

The NO–UK Cable System is an open cable system providing a total of eight dark fibre pairs and up to 216 Tbps system capacity, connecting Stavanger in Norway and Newcastle in the United Kingdom (UK). The NO–UK cable system has achieved a record-breaking 800Gbps line rate using Ciena’s GeoMesh Extreme, powered by WaveLogic 5 Extreme coherent optical technology. 

The NO–UK is part of a larger European fibre network established by Altibox Carrier, connecting Norway to important digital hubs such as London, Brussels, Amsterdam and Hamburg. 

Stavanger–Oslo fibre highway

We have recently extended the NO–UK backbone fibre highway from Stavanger to Oslo, allowing for access to several data centres in the Norwegian capital with reduced latency.  The link currently consists of 144 fibre pairs with the option to extend to several hundred.  

Skagen Fiber West

The Skagen Fiber West is a 170 km repeaterless submarine cable connecting Norway (Larvik) and Denmark (Hirtshals). 

The Skagen Fiber cable system consists of 48 fibre pairs, provides over 1920 Tbps of system capacity and a designed round-trip delay (RTD) of approximately 1.7 ms between the Larvik cable landing stations in Norway and Hirtshals cable landing station in Denmark. On the Norwegian side, the cable meets up with Altibox’ extensive national fibre network allowing for low latency connectivity to any of the major data centre locations, such as Stavanger, Rjukan and Oslo.
