Ko Olina, HI, United States: Submarine Cable Landing Point

Ko Olina is a coastal location on the island of Oahu, Hawaii, within the United States, and serves as a submarine cable landing point in the central Pacific. One submarine cable lands here, connecting Ko Olina into the broader network of inter-island submarine communications infrastructure across the Hawaiian archipelago. Although a single-cable terminus, it contributes to the intra-state connectivity that links the Hawaiian Islands to one another within the domestic United States network.

The cable landing at Ko Olina operates entirely within the United States, facilitating inter-island rather than intercontinental communications. This places Ko Olina in a distinctive category among submarine cable landing points: one oriented toward regional, domestic connectivity across the Hawaiian island chain rather than toward transoceanic corridors.

Cables Landing at Ko Olina

The Hawaii Inter-Island Cable System (HICS) is the sole submarine cable landing at Ko Olina. Measuring 479 kilometers in length and reaching ready-for-service status in 1994, HICS connects landing points entirely within the United States, linking sites across the Hawaiian Islands. As an inter-island cable system, it provides domestic submarine connectivity within Hawaii rather than international or transoceanic capacity. The cable's draft status reflects its position within the documented record of Hawaiian submarine cable infrastructure.

Regional Context

Within the United States, which hosts 75 submarine cables across 119 landing points, Ko Olina ranks in the top 72 percent of domestic landing points by cable count, hosting a single cable. Major United States landing points such as Boca Raton, FL, and San Juan, PR, each host six cables, while Ko Olina's Hawaiian neighbors Kapolei and Kawaihae host five and four cables respectively. Ko Olina therefore represents a more lightly served landing point within a nationally extensive submarine cable network.

Network Role

Ko Olina functions as a single-cable terminus dedicated to inter-island connectivity within Hawaii. The Hawaii Inter-Island Cable System, landing here since 1994, links domestic endpoints across the Hawaiian archipelago, enabling submarine-based communications between islands that would otherwise rely entirely on satellite or aerial means. Ko Olina does not currently serve as a gateway for intercontinental or transoceanic cable systems based on its present cable inventory.

As a single-cable landing point in a state where peers such as Kapolei and Kawaihae support multiple cables, Ko Olina occupies a more limited but defined position in the Hawaiian submarine cable graph, anchoring one segment of the inter-island system that keeps the Hawaiian Islands connected to one another by undersea infrastructure.
