Connecting Communities

The Hawaiian Islands Fiber Link (HIFL) is a next-generation, carrier-neutral, open access, unrepeatered submarine cable system designed to enhance inter-island broadband infrastructure across Hawai‘i. The project entails the deployment of a high-capacity subsea fiber optic network interconnecting O‘ahu, Hawai‘i (Big Island), Maui, Kaua‘i, Lāna‘i, and Moloka‘i, enabling scalable, low-latency, and resilient connectivity between the islands.

HIFL Middle Mile
The Interisland Backbone of Connect Kākou

As a part of the Connect Kākou initiative, the HIFL project provides the “Middle Mile” backbone needed to connect the islands and enable high-speed internet access statewide. This infrastructure, combined with “Last Mile” connections that reach directly into communities, will empower local providers to deliver high-quality internet to homes, schools, and businesses across the islands.

HIFL will connect fiber bandwidth from long-haul network stations across Hawai‘i.
