NO-UK, the submarine cable system between Norway and the United Kingdom, has achieved a record-breaking line rate of 800 Gb/s. This unprecedented data transmission speed will allow greater capacity, faster speeds, and a greener offering along with lower energy consumption.
The open submarine cable system features eight fibre pairs, runs for 700 km between Stavanger (Norway) and Newcastle (UK). It is also the shortest low-latency direct submarine route between the two nations. The system was developed by Altibox Carrier, supplied by Xtera, and is managed by specialist consultants SubSea Networks.

Altibox selected Ciena’s GeoMesh Extreme, leveraging Ciena’s WaveLogic 5 Extreme technology and 6500 Packet-Optical Platforms, supporting up to 35Tb/s per fibre pair. The design and cable validation exercise was conducted according to the new International Telecoms Union (ITU) submarine cable standard for open cables, known as ITU-T G.977.1.
Svein Arild Ims, Director, Altibox Carrier, said, “NO-UK has been developed to support the evolving requirements of businesses in Norway. We wanted it to deliver the highest bandwidth and capacity available across a submarine network in a sustainable way, and Ciena’s GeoMesh Extreme, combined with Xtera’s unique wide-bandwidth and low-noise repeater design, has achieved exactly that. The network has exceeded our expectations in every way and sets the standard for future connectivity between Norway and the UK.”
