Daru, Papua New Guinea: Submarine Cable Landing Point

Daru is the capital of the Western Province of Papua New Guinea, situated along the country's coastline as one of fifteen submarine cable landing points distributed across the nation. A single submarine cable comes ashore at Daru, connecting the town into a broader domestic and regional network. That cable, the Kumul Domestic Submarine Cable System, links Papua New Guinea with Indonesia, placing Daru within a corridor that spans both domestic inter-island connectivity and cross-border regional links between Papua New Guinea and its western neighbor.

Papua New Guinea's submarine cable infrastructure spans fifteen landing points served by five cables in total, with an average cable length of approximately 5,179 km. Daru's single cable nonetheless situates the town within a meaningful segment of that national network, providing a connection point for the Western Province into the broader submarine cable graph of the region.

Cables Landing at Daru, Papua New Guinea

The Kumul Domestic Submarine Cable System is the sole submarine cable landing at Daru. The system has a total length of 5,457 km and reached ready-for-service status in 2019, with its current status listed as draft. Beyond Daru, the cable connects other points within Papua New Guinea as well as Indonesia, making it a system that serves both domestic connectivity across Papua New Guinea's dispersed island geography and an international link to Indonesia. It is the longest cable among those landing in Papua New Guinea relative to the national average, exceeding the country's mean cable length of 5,179 km.

Regional Context

Among Papua New Guinea's fifteen submarine cable landing points, Daru sits alongside several single-cable locations including Alotau, Arawa, Kavieng, and Kerema, each hosting one cable. Port Moresby leads the national network with four cables landing there, while Madang hosts two. Daru's position as a single-cable landing point places it in the same tier as these other regional towns, ranked within the top 87 percent of Papua New Guinea landing points by cable count.

Network Role

Daru functions as a single-cable terminus within Papua New Guinea's submarine cable network, serving as the Western Province's point of entry into the Kumul Domestic Submarine Cable System. Through this cable, Daru is connected both to other landing points within Papua New Guinea and to Indonesia, enabling a cross-border link alongside domestic inter-island connectivity. This dual domestic and international reach, carried by a single system of 5,457 km, distinguishes Daru from landing points that are served exclusively by purely domestic routes.

Within the national submarine cable graph, Daru represents one of several distributed landing points that extend connectivity beyond Papua New Guinea's main centers, contributing to the geographic spread of undersea cable infrastructure across the country's Western Province and into the wider regional network connecting Papua New Guinea with Indonesia.
