Singaraja, Indonesia: Submarine Cable Landing Point

Singaraja is a port town located on the northern coast of Bali, Indonesia, serving as the seat of Buleleng Regency. Its position on Bali's northern shoreline places it along a stretch of coastline that connects the island to Indonesia's broader submarine cable network. One submarine cable lands at Singaraja, linking this Balinese port to Indonesia's domestic connectivity infrastructure.

The single cable serving Singaraja is the Barat Timur Indonesia-2 (BTI-2), a domestic system that connects multiple points within Indonesia. As its name suggests — Barat Timur meaning "West East" in Indonesian — this cable is oriented as an intra-national corridor, running along the Indonesian archipelago rather than reaching beyond the country's borders. Singaraja's role within this system positions it as a waypoint in the domestic submarine cable geography of Indonesia, contributing to the east-west connectivity that the BTI-2 system is designed to serve.

Cables Landing at Singaraja

The Barat Timur Indonesia-2 (BTI-2) is the sole submarine cable landing at Singaraja. This system has a total length of 11,600 kilometres and is currently in draft status. All endpoints on this cable are located within Indonesia, making it an entirely domestic system. Its considerable length reflects the geographic scale of the Indonesian archipelago, which the BTI-2 is designed to bridge. Singaraja, on the northern coast of Bali, represents one node in a cable system that spans a significant portion of Indonesian territory.

Regional Context

Within Indonesia's submarine cable network — which encompasses 70 cables across 139 landing points — Singaraja hosts a single cable, placing it in the top 62% of Indonesian landing points by cable count. Compared to major hubs such as Batam (20 cables), Jakarta (9 cables), and Tanjung Pakis (9 cables), Singaraja is a smaller, more specialised node. Its significance lies in extending domestic cable infrastructure to northern Bali rather than serving as a high-density international interconnection point.

Network Role

Singaraja functions as a single-cable terminus within Indonesia's domestic submarine network, connected exclusively through the BTI-2 system to other points along the Indonesian archipelago. The BTI-2's east-west orientation suggests that Singaraja plays a role in extending connectivity across the island chain, with Bali serving as one landmark along that corridor. This is not a multi-cable hub attracting international routes, but rather a domestic waypoint that brings submarine cable infrastructure to a northern Balinese port town with an established maritime heritage.

Singaraja's presence on the BTI-2 system illustrates how Indonesia's domestic cable ambitions extend beyond Java and Sumatra to encompass Bali's northern coast, reinforcing the archipelagic nature of the country's approach to submarine connectivity.
