Network Redundancy

A separate pair of fiber optic cables connects Juneau to Seattle, Juneau to Anchorage, Anchorage to Fairbanks, Anchorage to Seattle (AU-E) Anchorage to Warrenton (AU-W) and Anchorage to Ketchikan and Ketchikan to Warrenton.

Route Diversity

The Alaska United Network achieves complete route diversity to Anchorage and Seattle by using routes on both AU-East and AU-West to create a physically diverse ring interconnecting these locations. Juneau has a diverse ring through Southeast cable to Ketchikan and the Segment 3 AU-W leg to Ketchikan. Fairbanks has complete route diversity between fiber along the pipeline corridor and fiber along Parks.

Total Design Capacity

220 billion bits per second can be provided in a diversely routed ring configuration utilizing AU-East and AU-West cable segments. Another 530 billion bits per second can be provided as standalone capacity on AU-West. AU-North capacity can be increased to greater than a TB/s through advancements in terrestrial transmission abilities.
