Tokelau Submarine Cable

Overview

The Tokelau Submarine Cable is a regional submarine telecommunications system designed to connect the three atolls of Tokelau: Atafu, Fakaofo, and Nukunonu. With a total length of 250 km, the cable was officially Ready for Service (RFS) in 2023. Owned and operated by Teletok, the cable represents a significant milestone in improving connectivity and communication infrastructure in this remote region of the South Pacific. The system facilitates reliable voice, data, and internet services, addressing the unique challenges of providing modern telecommunications to small and isolated island communities.

Tokelau, a dependent territory of New Zealand, consists of three coral atolls located approximately 500 kilometers north of Samoa. Before the deployment of the Tokelau Submarine Cable, the islands relied on satellite-based systems for connectivity, which were often limited in bandwidth and prone to latency issues. This new cable system enhances the quality and reliability of communication services, fostering social and economic development in the region.

Route and Landings

The Tokelau Submarine Cable connects the three main atolls of Tokelau: Atafu, Fakaofo, and Nukunonu. These atolls are spread across a vast expanse of the South Pacific Ocean, with each separated by dozens of kilometers of open water. The cable’s relatively short length of 250 km reflects the compact geographical layout of Tokelau, as it exclusively serves the internal connectivity needs of the territory.

Atafu, the northernmost atoll, is the first landing point of the cable. From there, the cable extends southward to Nukunonu, the central atoll, which serves as the administrative center of Tokelau. The final segment connects Nukunonu to Fakaofo, the southernmost atoll. By linking these three atolls, the cable ensures that all of Tokelau’s inhabited areas have access to improved telecommunications infrastructure. The route was carefully planned to navigate the shallow waters and coral reefs surrounding the atolls, minimizing environmental impact while maximizing efficiency.

Ownership and History

The Tokelau Submarine Cable is fully owned and operated by Teletok, the national telecommunications provider of Tokelau. Teletok has played a central role in the development and implementation of this project, ensuring that the cable meets the specific needs of the local population. The cable was completed and became operational in 2023, marking a significant upgrade from the previous reliance on satellite connectivity.

As a small and remote territory, Tokelau faced unique challenges in deploying submarine cable infrastructure, including logistical difficulties and the need for specialized engineering to accommodate the atolls’ geographic features. The successful implementation of the Tokelau Submarine Cable reflects both the determination of local stakeholders and the importance of modern telecommunications in fostering regional development. The cable is a critical component of Tokelau’s strategy to bridge the digital divide and improve access to essential services such as education, healthcare, and e-governance.

What Our Measurements Show

Our live monitoring of the Tokelau Submarine Cable has identified 12 measured corridors within the system. The best recorded round-trip time (RTT) is 57 milliseconds, while the average RTT across all measurements is 290 milliseconds. These figures indicate a significant improvement in latency compared to the satellite-based systems previously used in Tokelau, which were subject to much higher delays.

The cable’s performance metrics demonstrate its capability to support a range of applications, including high-quality voice calls, video streaming, and data-intensive services. The reduction in latency has a direct impact on the user experience, enabling smoother and more reliable communication for the residents of Atafu, Fakaofo, and Nukunonu. By providing consistent and efficient connectivity, the Tokelau Submarine Cable is a transformative development for the region, enhancing both quality of life and economic opportunities.
