Summary

• Space Norway has awarded Ciena a turnkey contract covering existing Svalbard subsea infrastructure and the planned Arctic Way system.
• The project includes optical transmission equipment, spectrum sharing and software-based network control.
• Arctic Way is expected to enter service in 2028, linking mainland Norway, Jan Mayen and Svalbard while complementing existing cables and satellite services.

Space Norway has selected Ciena to modernise its existing Svalbard submarine cable systems and provide optical networking technology for the planned Arctic Way cable, extending communications infrastructure that supports scientific research, commercial activity and national security operations across the Arctic.

The turnkey contract covers network design, deployment and equipment for existing cable systems as well as the new connection between mainland Norway, Jan Mayen and Svalbard. Arctic Way is expected to begin service in 2028.

Ciena will supply its 6500 Optical Platform, WaveLogic 6 Extreme transmission technology, Spectrum Sharing capabilities and Navigator Network Control Suite. Space Norway intends to use common equipment across both the older and new networks to improve operational consistency and support future capacity requirements.

The company operates communications infrastructure in a region where geographic isolation, difficult weather conditions and limited alternative routes can make network failures particularly disruptive.

Modernising existing systems while introducing a new cable gives Space Norway a route towards additional capacity and network diversity without immediately replacing every part of its current subsea infrastructure.

Maintaining communications in the Arctic

Svalbard supports scientific institutions, satellite ground operations, commercial services and public organisations that depend on reliable connections with mainland Norway and the wider international network.

Submarine fibre can provide substantial communications capacity between fixed locations, but failures are difficult to repair when cable routes pass through remote waters with challenging operating conditions.

Maintenance work may require specialist vessels, replacement components and access to areas where weather and sea conditions limit the available repair window. Where alternative terrestrial infrastructure is unavailable, an interruption can place considerable pressure on backup communications services.

Space Norway’s current Svalbard systems therefore remain important even as the company develops new infrastructure. Updating their transmission equipment can extend their useful operating life while the new Arctic Way cable is prepared for service.

Optical technology has advanced considerably since earlier generations of submarine infrastructure were installed. Modern terminal equipment can sometimes carry more information over existing fibres, provided that the physical cable and supporting components remain in suitable condition.

Such upgrades can avoid some of the costs and lead times involved in laying new cable. They do not, however, remove the risk of physical damage or guarantee that older infrastructure can continue operating indefinitely.

Space Norway’s longer-term strategy involves combining the new route with existing systems for as long as continued operation remains technically and economically viable.

The company’s earlier project documentation describes Arctic Way as a means of providing redundant submarine connectivity, including a connection to Jan Mayen requested by the Norwegian Armed Forces.

The eventual resilience of the arrangement will depend on the physical routes, operational independence, available capacity and the procedures used to restore services following incidents.

One optical platform across several generations

Ciena’s 6500 platform provides optical transmission capabilities used to carry large volumes of information through fibre networks. Its WaveLogic 6 Extreme technology is designed to support high-capacity connections, with performance depending on the characteristics of the cable and the equipment deployed.

Spectrum Sharing allows the available optical transmission spectrum to be allocated between services, providing flexibility where different organisations or applications require access to the same underlying infrastructure.

Navigator Network Control Suite adds software for monitoring and managing network services, helping operators examine performance, coordinate changes and identify problems across geographically distributed equipment.

These capabilities can be particularly useful for remote infrastructure because technical teams cannot easily reach every component when a problem occurs.

Remote visibility may help engineers distinguish between service faults, equipment problems and changes in transmission performance, allowing a more informed response before physical intervention becomes necessary.

However, management software cannot repair a damaged submarine cable or overcome every consequence of an infrastructure failure. Its value depends on the reliability of monitoring information, the availability of alternative paths and the effectiveness of operational procedures.

Using one supplier’s technology across multiple networks can reduce the number of different systems that engineers must maintain and simplify the management of software, spare parts and technical expertise.

It can also create a stronger dependence on that supplier for future upgrades, maintenance and compatibility. Space Norway will need to manage these relationships across infrastructure expected to remain operational for many years.

The contract announcement does not provide specific capacity figures, verified operating cost reductions or a completed deployment timetable for each existing cable.

Ciena and Space Norway expect the standardised approach to generate operational efficiencies, but those benefits will need to be demonstrated through the installation and subsequent operation of the network.

Submarine and satellite systems serve different needs

Space Norway operates satellites, ground stations, fibre networks and submarine cable infrastructure. Combining these technologies allows the company to provide communications services across regions where conventional terrestrial networks may be difficult or costly to develop.

Fibre connections can offer substantial dedicated capacity between fixed locations, while satellite services can reach remote sites without requiring a continuous cable route to every destination.

The two technologies also face different risks. Submarine cables are exposed to physical damage along their routes, whereas satellite services depend on spacecraft, ground infrastructure, available radio spectrum and the operating characteristics of the network.

Using both may increase flexibility, but genuine resilience requires enough capacity and appropriate arrangements to transfer communications when one system becomes unavailable.

Critical services may also have requirements concerning latency, security, continuity and access that cannot be met equally well by every available connection.

The new Arctic Way system is expected to extend submarine connectivity to Jan Mayen while adding another route serving Svalbard. Its development is supported by Norwegian public investment and reflects the operational importance of communications infrastructure in the region.

Space Norway is owned by the Norwegian Ministry of Trade, Industry and Fisheries, and its infrastructure serves public, defence and commercial customers.

Those responsibilities give the cable project a broader purpose than ordinary consumer connectivity. Research stations, government operations and commercial services may depend on reliable transmission of information between remote facilities and mainland systems.

Nevertheless, the announcement does not disclose particular security arrangements, resilience tests or operational performance guarantees for the completed network.

Descriptions of the system as secure or resilient should therefore be understood as its intended design characteristics rather than proof that specific capabilities have already been demonstrated.

The programme combines work on infrastructure already carrying traffic with a new cable that has yet to enter service. Its immediate milestones will involve deploying and integrating Ciena’s equipment across the existing routes, while Arctic Way continues towards its expected 2028 introduction.

Successful commissioning will provide a basis for assessing the additional capacity and resilience achieved. Until then, the contract establishes the technology and delivery approach, with the network’s eventual operational performance still to be demonstrated.
