Hilo is the county seat of Hawaiʻi County and the largest settlement on the Island of Hawaiʻi, situated on the eastern shore of the Big Island in the central Pacific Ocean. As a submarine cable landing point, Hilo connects the Island of Hawaiʻi to the broader network of undersea fiber infrastructure serving the Hawaiian archipelago. One submarine cable is currently associated with this landing point, linking Hilo to other points within the United States.
The cable landing here, the Hawaiian Islands Fiber Link (HIFL), is an intra-United States system that, by its name and country pairing, serves an inter-island corridor within the Hawaiian Islands. With a scheduled ready-for-service date of 2026, Hilo is positioned to become an active node in a regional fiber route connecting Hawaiian communities across the Pacific island chain.
The Hawaiian Islands Fiber Link (HIFL) is a 740-kilometer submarine cable system with a draft ready-for-service date of 2026. All endpoints on this cable are located within the United States, indicating that it functions as an intra-national, inter-island connection within the Hawaiian archipelago. As a draft system, its final configuration remains subject to confirmation, but Hilo is listed among its landing points, placing the city within this emerging regional fiber corridor.
Within the United States, submarine cable infrastructure is spread across 160 landing points, with major hubs such as Boca Raton, FL, and San Juan, PR, each hosting eight cables, and West Coast sites like Hermosa Beach, CA, and Grover Beach, CA, serving as multi-cable gateways. On the Hawaiian side, Kapolei, HI, hosts five cables and represents the most cable-dense landing point in the state. With a single cable, Hilo ranks in the top 69 percent of United States landing points by cable count, reflecting the relative concentration of submarine infrastructure at a smaller number of high-volume sites nationwide.
Hilo functions as a single-cable terminus within the current and planned submarine cable landscape. The Hawaiian Islands Fiber Link connects it to other U.S. landing points across the Hawaiian island chain, enabling intra-archipelago fiber connectivity for the largest settlement on the Island of Hawaiʻi. As a city of more than 44,000 residents and the largest populated place in Hawaiʻi outside of the Greater Honolulu Area, Hilo's inclusion in the HIFL system extends dedicated submarine fiber capacity to a part of the state that relies on inter-island connections for its communications infrastructure.
As a single-cable landing point, Hilo does not yet function as a multi-cable hub in the way that other U.S. coastal sites do, but its entry into the submarine cable graph through the HIFL marks a meaningful extension of the Hawaiian inter-island fiber network to the eastern side of the Big Island.
