Paniolo Cable Network

Overview

The Paniolo Cable Network is a domestic submarine cable system serving the Hawaiian Islands, entirely within the United States. Spanning 576 km, it connects seven landing points across the Hawaiian island chain, providing inter-island connectivity through a series of landings on Oahu, Molokai, the Big Island, Maui, and Kauai. The system operates as an intra-state network rather than an intercontinental link, distinguishing it from the long-haul transoceanic cables that also land in the United States.

Route and Landings

All seven landing points of the Paniolo Cable Network are located in the state of Hawaii, United States. On Oahu, the cable lands at Hawaii Kai and Makaha. On Molokai, it comes ashore at Kaunakakai. The Big Island of Hawaii is served by a landing at Kawaihae. On Kauai, the cable lands at Kekaha. Maui is served by two landing points: Lahaina on the island's west coast and Makena on its southern shore.

Ownership and Operators

The Paniolo Cable Network is owned and operated by Hawaiian Telcom, the primary telecommunications provider serving the Hawaiian Islands. As a single-owner system, Hawaiian Telcom holds full operational responsibility for the network.

Status and Timeline

The Paniolo Cable Network entered service in 2009 and has been operational for approximately 17 years. It continues to serve as a live, active cable system connecting the Hawaiian island landing points described above.

Regional Context

The United States hosts 75 submarine cables landing across 119 points, with an average cable length of around 5,553 km. At 576 km, the Paniolo Cable Network is considerably shorter than the regional average, longer than only about 10% of the other cables touching the same country. This reflects its nature as a short-haul, intra-island system rather than an oceanic trunk route. Among the cables sharing the United States as a landing country, peers such as the Southern Cross Cable Network, Asia-America Gateway, and the forthcoming Project Waterworth operate at scales of 20,000 km or more, underscoring how the Paniolo Cable Network occupies a distinct and specialized niche within the broader U.S. submarine cable landscape.

Strategic Role

By linking seven landing points across five Hawaiian islands within a single 576 km system, the Paniolo Cable Network supports direct inter-island telecommunications connectivity in Hawaii. Its seven landings across the archipelago reflect a design oriented toward broad island coverage rather than a single point-to-point connection, enabling multi-island reach under unified ownership by Hawaiian Telcom.
