Stavanger, Norway – NO-UK Com AS and Altibox are pleased to announce that Provisional Acceptance has been granted for the NO-UK submarine cable system linking Newcastle and Stavanger. This milestone marks a significant achievement in North Sea cable system construction, with the project being completed just 22 months after the Supply Contract with Xtera came into force last year. The 8 fibre pair system, which forms part of Altibox Carrier’s network, is being lit with advanced terminal equipment from Ciena.

NO-UK is a new high-capacity submarine cable linking 700km across the North Sea between Norway and the UK, that will significantly improve data connectivity for Norway. The system has been designed and manufactured by Xtera, utilising their new high fibre count submerged amplifiers, and has armoured and buried cable for the entire route to maximise system protection and reliability.

“It’s great news for the project and for our investors that we have been able to complete the NO-UK system this year. We appreciate all the efforts of our turnkey contractor Xtera, marine installer Global Marine and specialist consultants Subsea Networks Ltd, to create a robust high-capacity connection between the Green Mountain and Stellium Data Centres,” said Geir Ims, Chairman of NO-UK Com AS.
