Tui-Samoa

Overview

Tui-Samoa is a regional submarine cable system spanning 1,693 kilometres across the central South Pacific. It connects three territories — Fiji, Samoa, and Wallis and Futuna — providing intra-Pacific connectivity across a corridor where overwater distances make terrestrial alternatives impossible. The cable is owned and operated by Samoa Submarine Cable Company.

Route and Landings

In Fiji, the cable lands at two points: Savusavu and Suva. These two landings serve different parts of the Fijian archipelago, with Suva being the national capital on Viti Levu and Savusavu located on Vanua Levu.

In Samoa, the cable comes ashore at Apia, the capital, and at Tuasivi on the island of Savai'i, providing connectivity to both of Samoa's main islands.

In Wallis and Futuna, the cable lands at Leava, on the island of Futuna, and at Mata-Utu, the territory's capital on Wallis island. Tui-Samoa represents the only submarine cable infrastructure reaching Wallis and Futuna.

Ownership and Operators

Tui-Samoa is solely owned by Samoa Submarine Cable Company. As a single-owner system, it reflects Samoa's national investment in dedicated submarine cable infrastructure to serve its own connectivity requirements and those of neighbouring territories.

Status and Timeline

The cable became ready for service in 2018 and has been operational for approximately eight years. It was the first submarine cable to reach Samoa and remains the only system connecting Wallis and Futuna to the broader regional network.

Regional Context

The South Pacific corridor served by Tui-Samoa also hosts several other cable systems of varying scale. Long-haul systems such as the Southern Cross Cable Network, Southern Cross NEXT, and the forthcoming Bulikula and APX East cables all land in Fiji, connecting the region to Australia, New Zealand, and the Americas over distances an order of magnitude greater than Tui-Samoa's 1,693 kilometres. The Manatua cable, which reached Samoa in 2020, is the one other system serving that country, running at roughly twice the length of Tui-Samoa. Among the cables sharing this corridor, Tui-Samoa is shorter than the majority, reflecting its purpose as a regional interconnector rather than a transoceanic trunk route. The Gondwana-2/Picot-2 system, at 1,515 kilometres and entering service in 2022, is the only peer cable of comparable length in this grouping.

Strategic Role

By landing at two points each in Fiji and Samoa, and providing the sole submarine link to both inhabited islands of Wallis and Futuna, Tui-Samoa serves a geographically dispersed set of communities across three distinct Pacific territories. Its dual landings in both Samoa and Wallis and Futuna offer a degree of in-country redundancy that is particularly meaningful given the isolation of these island groups. The cable ties together a cluster of Pacific territories that would otherwise depend entirely on satellite connections or indirect routing through longer regional systems.
