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.”
