Should your country prioritize the expansion of high-speed fibre infrastructure despite its environmental impact?
Midgard Infra has announced the extension of its existing Oslo-to-Stockholm fibre route into Finland. This infrastructure project includes a new, unrepeatered subsea crossing designed to avoid existing network paths.
Why it matters
The route expansion aims to increase network reliability by establishing a path that is fully separated from current subsea and terrestrial infrastructure. By bypassing shared landing points and rights-of-way, the system reduces the risk of simultaneous outages across multiple links.
The system utilizes an unrepeatered subsea cable, a design that omits optical amplifiers on the sea floor to simplify maintenance and power requirements. It is engineered to maintain physical isolation from existing infrastructure by utilizing independent landing points and rights-of-way.
The players
Midgard Infra
Formerly known as Altibox Carrier, this telecommunications provider manages regional subsea and terrestrial fibre infrastructure.
The details
The project extends the company's long-haul network by building a fully diverse path that shares no common landing points, cable routes, or rights-of-way with existing regional systems. An unrepeatered system — a cable setup lacking subsea signal boosters or repeaters — is employed to provide a direct connection between Stockholm and the Finnish destination. This architectural choice limits the potential for a single point of failure to impact both the legacy and new routes simultaneously.

The Tech Race
This deployment reflects the broader industry move to secure connectivity by avoiding congested and shared subsea routes. By deploying unrepeatered systems, Midgard Infra aligns with regional efforts to create redundant fibre paths across the Nordic region.
The new route provides increased capacity and physical redundancy for data moving between Sweden and Finland. Enterprise customers and network operators should see improved traffic routing options once the system enters service, though a specific launch date for commercial traffic remains unannounced.
The takeaway
The project highlights the increasing priority placed on path diversity in critical Nordic network corridors. Observers should track the integration of this new crossing into the broader Midgard Infra network map to determine when the link becomes available for commercial traffic.
