Telisai, Brunei

Telisai, Brunei: Submarine Cable Landing Point

Telisai is a coastal village in Tutong District, Brunei, situated approximately 17 kilometres from the district town of Pekan Tutong. Its position on the coast of Brunei makes it a point of connection to the international submarine cable network. One submarine cable lands at Telisai, linking Brunei directly into a major regional and intercontinental corridor spanning Southeast Asia and East Asia.

The cable landing at Telisai connects Brunei to a network that reaches Japan, China, the Philippines, and Singapore, placing this small coastal village within a system that bridges Southeast Asia to Northeast Asia. While Telisai hosts a single cable, that cable is one of the larger systems in the region, enabling Brunei's participation in a broad Pacific Rim communications corridor.

Cables Landing at Telisai

The Southeast Asia-Japan Cable (SJC) is the sole submarine cable landing at Telisai. Measuring 8,900 kilometres in length and reaching its ready-for-service date in 2013, the SJC connects Brunei with four other countries: China, Japan, the Philippines, and Singapore. The cable forms a substantial regional system linking Southeast Asian nations with Japan and China, and Telisai serves as Brunei's point of entry into this multi-country network.

Regional Context

Brunei's submarine cable infrastructure spans three landing points — Telisai, Tungku, and Mumong — together hosting five cables in total. Tungku is the most connected of the three, with three cables landing there, while both Telisai and Mumong each host a single cable. Telisai therefore occupies the lower tier of Brunei's landing point hierarchy by cable count, sharing that position with Mumong.

Network Role

Telisai functions as a single-cable terminus within Brunei's submarine cable geography. Through the Southeast Asia-Japan Cable, it enables connectivity between Brunei and a set of major economies across the Southeast Asia-Northeast Asia corridor, encompassing Singapore, the Philippines, China, and Japan. The SJC's 8,900-kilometre reach means that Telisai, despite hosting only one system, is anchored to one of the longer cable systems present in Brunei's network.

Within the regional submarine cable graph, Telisai's significance lies in diversifying the geographic distribution of Brunei's international cable landings across the country's coastline. Rather than concentrating all connectivity at a single point, Brunei's three landing points — including Telisai — spread the country's external cable connections across distinct coastal locations, with Telisai providing the SJC's landfall in Tutong District.
