Ciena has won a turnkey contract from Space Norway to upgrade the operator's existing Svalbard subsea cable systems and supply networking technology for the new Arctic Way cable, which is expected to enter service in 2028 carrying traffic between mainland Norway, Jan Mayen and Svalbard.

The deal gives Ciena responsibility for both design and deployment of the network. Space Norway, a state-owned satellite and infrastructure operator, will use the project to extend the operational lifespan of its existing subsea assets while adding capacity across one of the world's most remote and strategically sensitive regions.

Under the agreement, Ciena will deploy its 6500 Optical Platform fitted with WaveLogic 6 Extreme transponders, alongside Spectrum Sharing technology. The vendor will also roll out its Navigator Network Control Suite, a software layer designed to give Space Norway greater visibility and control over the finished network.

What does the deal change for Arctic connectivity?

The practical effect is twofold. First, the upgrade pushes more life and more capacity out of infrastructure already sitting on the seabed, rather than requiring a full replacement. Second, Arctic Way adds a new route linking the Norwegian mainland, the island of Jan Mayen and the Svalbard archipelago, hardening connectivity for a region where alternatives are scarce.

Pia Birgitte Bruhn, Acting Vice President of Cable Systems at Space Norway, framed the investment in operational terms. "Reliable connectivity is essential in the Arctic, where our infrastructure supports critical activities and demanding operational requirements," she said.

"By working with Ciena, we are extending the operational life of our existing Svalbard cable systems while preparing Arctic Way for service," Bruhn added. "This investment will strengthen the resilience and capacity of our subsea network and support the region's long-term connectivity needs."

Svalbard hosts a concentration of scientific and satellite-ground-station activity that depends heavily on the existing cable links, which makes the resilience argument more than vendor marketing. The Arctic Way route, scheduled for service in 2028, spreads that dependence across newer plant.

A broader Ciena momentum

The Space Norway win adds to a run of European business for the US vendor. Openreach has tapped Ciena for a UK-wide 800G rollout, and e& UAE recently expanded its network infrastructure with Ciena equipment. The company has also launched a $200 million venture capital programme, signalling appetite to invest beyond its core optical transport business.

Thomas Soerensen, Ciena's VP of Global Subsea and MOFN, said: "Organisations delivering mission-critical connectivity in remote and harsh environments need infrastructure built for resilience and long-term durability."

"Ciena is proud to be selected by Space Norway to enable reliable and high-speed connectivity in one of the world's most strategically important and challenging Arctic environments, safeguarding communications well into the future," he said.

The vendors' claims about durability will be tested by the environment itself; subsea cable in Arctic waters faces ice scour and harsh conditions that few other routes match.

With Arctic Way now scheduled to enter service in 2028, the next milestone to watch is the marine survey and lay schedule, which will determine whether Space Norway and Ciena can hold that date in one of the planet's least forgiving construction windows.
