Honotua

Overview

The Honotua submarine cable system spans a total length of 4,805 kilometers, connecting French Polynesia to the United States via the Hawaiian Islands. Operational since 2010, the cable serves as a critical telecommunications link for French Polynesia, enabling improved connectivity across its islands and to international networks. Owned and operated by OPT French Polynesia (Office des Postes et Télécommunications de Polynésie française), Honotua plays a key role in supporting the region's digital infrastructure and bridging the vast distances of the Pacific Ocean. Its design ensures connectivity not only between French Polynesia and Hawaii but also among several of the territory's major islands.

Honotua's deployment highlights the strategic importance of undersea cables in connecting remote island communities to global communication networks. Its trans-Pacific route provides French Polynesia with a direct link to Hawaii, which serves as a hub for onward connections to the mainland United States and other international destinations. The system contributes to economic development, education, and access to digital services in one of the world's most isolated regions.

Route and Landings

The Honotua cable has six landing points, five of which are in French Polynesia and one in the United States. In French Polynesia, the cable lands at Papenoo on the island of Tahiti, Moorea, Huahine, Uturoa on Raiatea, and Vaitape on Bora Bora. These landings ensure connectivity across several key islands within the archipelago, addressing the challenges posed by the region's dispersed geography. By linking these islands, Honotua facilitates inter-island communication and access to international networks.

On the United States side, the cable lands at Kawaihae on the Big Island of Hawaii. This landing point provides a gateway to broader trans-Pacific and global networks. The route crosses the Pacific Ocean, a vast and deep expanse, requiring advanced engineering to ensure the cable's durability and performance. The selection of these landing sites reflects the need to balance geographic coverage within French Polynesia with strategic access to international hubs in Hawaii.

Ownership and History

Honotua is wholly owned and operated by OPT French Polynesia, the public telecommunications authority of the territory. As the sole owner, OPT French Polynesia is responsible for the cable's operation, maintenance, and upgrades. This ownership structure allows the territory to maintain control over its critical telecommunications infrastructure, ensuring that it meets the specific needs of French Polynesia's residents and businesses.

The cable was commissioned and became ready for service in 2010, marking a significant milestone in the region's telecommunications history. Prior to Honotua, French Polynesia relied heavily on satellite connectivity, which is more expensive and offers lower performance compared to submarine cables. The introduction of Honotua represented a transformative step in reducing latency, increasing bandwidth, and improving the reliability of communications for the islands.

What Our Measurements Show

Our live monitoring of the Honotua cable system reveals consistent performance metrics that align with its trans-Pacific design and purpose. Over 107 measured corridors, the cable has demonstrated an average round-trip time (RTT) of 143 milliseconds, with the best recorded RTT at 108 milliseconds. These figures reflect the physical distance of approximately 4,805 kilometers between French Polynesia and Hawaii, as well as the cable's efficient operation.

The latency measurements highlight the system's effectiveness in providing low-latency communication compared to satellite-based alternatives. The cable's performance is crucial for supporting modern applications such as video conferencing, cloud computing, and other bandwidth-intensive services. By enabling faster and more reliable connectivity, Honotua enhances the quality of life and economic opportunities for the communities it serves, while also integrating French Polynesia more closely into the global digital ecosystem.
