Phase 1: Alaska

Construction is complete on the first segment of the multi-phase Quintillion Subsea Cable System. Phase 1 – Alaska is a 1200 mile submarine fiber optic cable main trunk line between Nome and Prudhoe Bay, Alaska. Additional branches are installed into the Alaskan communities of Kotzebue, Point Hope, Wainwright and Utqiagvik (Barrow). The system is IN SERVICE since December 1, 2017, enabling 21st Century communications in the Alaska Arctic for the first time.

The Quintillion Cable System, a new terrestrial fiber between Fairbanks and Prudhoe Bay, Alaska, has been installed along the Dalton Highway and is now IN SERVICE. At Fairbanks, the new fiber connects to existing networks reaching Anchorage, Alaska, Portland, Oregon and Seattle, Washington, providing fiber link between the Continental United States and the North American Arctic.


The Pacific segment, Phase 2: Asia – Pacific Northwest, is planned to extend the backbone cable from the Nome branching unit southeast to the Pacific Northwest, west to Asia, with options for additional branches into Alaska. Phase 2 will create an option for a diverse path from Alaska to the continental United States and Asia.

Phase 3: Canada-United Kingdom

The Canada – United Kingdom segment, Phase 3, is intended to extend the subsea system east of the Prudhoe Bay, Alaska branching unit along the Northwest Passage to Canada and on to the United Kingdom. Final route selection will be based on client needs. Phase 3 will provide a secure, low latency route from Europe to Asia, and a diverse route option out of North America to Europe.
