Inter-city Ring

Connecting Oslo, Kristiansand, Stavanger and Bergen

The Inter-City Ring terrestrial fiber system connects four of Norway’s largest cities: Oslo, Kristiansand, Stavanger, and Bergen. 


About the Inter-City Ring

The Bulk Inter-City Ring (ICR) is the newest fiber infrastructure connecting the major cities in the southern part of Norway: Oslo, Kristiansand, Stavanger and Bergen.

The system is built in partnership with Bane Nor, the Norwegian railway company, and Bulk holds multiple fiber pairs, well protected in ducts laid in concrete culverts along the railway. The digital distances between the end points are unmatched.

The ICR connects to Bulk OS-IX DC in Oslo and Bulk N01 Campus DC in Kristiansand and brings the southern part of Norway closer to the rest of the world.

The ICR connects directly to Bulk systems Havfrue and Havsil in N01 Campus, Kristiansand.
