Stavanger, Norway – 8 October 2026 — Midgard Infra, formerly Altibox Carrier, today announced that it will extend its recently announced Oslo–Stockholm long-haul fibre route onward into Finland, adding a fully diverse, unrepeatered subsea crossing and establishing a continuous, physically diverse trans-Nordic corridor linking Norway, Sweden and Finland.
The extension builds directly on the diversity-first design principle behind the Oslo–Stockholm route. Where that route delivers full physical separation from existing terrestrial infrastructure across the corridor, the Finnish extension carries the same principle across water — engineered from the outset to share no common landing point, cable, or right-of-way with existing systems serving Sweden-Finland.
The subsea segment will be deployed as a repeaterless cable system, simplifying maintenance and restoration and reinforcing the resilience case at the heart of Midgard Infra’s Nordic strategy.
The new segment will land on the coast northeast of Stockholm and southwest of Finland, spanning approximately 200 kilometres and carrying 144 fibre pairs. Construction is scheduled to commence in early 2027, with the system expected to enter service in 2029.
A Single, Diverse Spine Across the Nordics
With the Finnish extension, Midgard Infra moves from a two-country route to a continuous Nordic spine, giving carriers, hyperscalers and data centre operators a single, physically diverse path between Norway, Sweden and Finland under one operator.
Finland has become one of Europe’s most active destinations for hyperscale and colocation development, drawn by abundant renewable power, a naturally cool climate, and growing demand for low-latency capacity into and out of the Nordic region. That momentum has been sharpened by the rise of large-scale AI compute: Finland is among the European sites selected to host one of the EU’s designated «AI factories», and the wave of AI training and inference capacity being built out across the country places extraordinary demands on the networks that feed these sites. Direct, diverse fibre connectivity into Finland — independent of the established routes the market already relies on — addresses a concentration of risk that has grown alongside that demand.
Engineered for Diversity and Scale
Consistent with the Oslo–Stockholm route, Midgard Infra has mapped existing infrastructure across the corridor and will ensure the Finnish extension shares no common point of failure with incumbent systems. The cable system will be built to current best practice and will support high-capacity DWDM deployments, with headroom for next-generation optical technologies as network demand evolves.
Quote — Svein Arild Ims, Chief Executive Officer, Midgard Infra:
«Finland is fast becoming one of the places where Europe builds and runs its largest AI systems, and compute on that scale is only as useful as the connectivity feeding it. A diverse corridor that stops at the Swedish border isn’t a diverse Nordic corridor; it’s half a solution. By taking the system subsea on a fully unrepeatered crossing, with every active component sitting safely onshore, we are not adding complexity to reach Finland, we are removing it. That is precisely the kind of end-to-end resilience the operators building this next wave of AI infrastructure are now asking us for.»
