Far North Fiber is a 14,000km submarine cable system linking Europe and Asia through the Arctic region, from Japan, via the Northwest Passage, to Europe with landings in the US (Alaska) and Canadian Arctic. European landings are planned in Norway, Finland and Ireland.

Far North Fiber is invested by Far North Digital, LLC (US Alaskan company), True North Global Networks (Canadian affiliate of Far North Digital), Cinia (Finland) and Arteria (Japan).

In December 2021, Cinia and Far North Digital LLC announced a joint effort to build the Far North Fiber subsea cable linking Asia and Europe. In Feburary 2022, Japanese Arteria joined the consortium.

Far North Fiber (FNF) cable system consists of 12 fiber pairs, with 10 FPs for express route and 2 FPs reserved for local add/drops, with design capacity up to 150Tbps:

• Express Spectrum: 60λ X 200G/FP = 12 Tbps/FP without regeneration.

• Add Drop Spectrum: 60λ X 250G/FP = 15 Tbps/FP with regeneration.

• Low Latency Express Capacity: 10FP x 12 Tbps/FP = 120 Tbps

• Local add/drop capacity: 2FP x 15 Tbps/FP = 30 Tbps

Far North Fiber (FNF) cable system is porjected to cost approximately CAD1.48 billion (or US$1.17 billion, or Euro 1 billion), supplied by Alcatel Submarine Networks (ASN), expected to be ready for service bythe end of the year 2025. 

There was a similar project, Arctic Fiber, planned to connect Japan and Europe through Canadian Arctic, with its Alaska portion activated in 2017 and no further progress on other portions.
