Beculuk, Indonesia

Beculuk: Submarine Cable Landing Point

Beculuk is a submarine cable landing point located in Indonesia, a nation whose extensive archipelagic geography makes submarine cable infrastructure essential for connecting its many islands. As a coastal landing point, Beculuk serves as a terminus for submarine cable connectivity within the Indonesian archipelago. One submarine cable lands at Beculuk, linking it to other points within Indonesia and contributing to the country's broader intra-national cable network.

The single cable serving Beculuk, JaKa2LaDeMa, is a domestic cable connecting multiple Indonesian locations. This positions Beculuk as a node in the inter-island communications corridor that runs between Indonesian cities and regions, rather than as an intercontinental gateway. With a length of 1,700 km, the JaKa2LaDeMa cable spans a meaningful distance across Indonesian waters, reinforcing connectivity among the country's dispersed island communities.

Cables Landing at Beculuk

JaKa2LaDeMa is the sole submarine cable landing at Beculuk. The cable stretches 1,700 km and was ready for service in 2010, with a draft designation noted at the time. All endpoints on the JaKa2LaDeMa cable are located within Indonesia, making it a purely domestic submarine cable. Its name suggests connections between several Indonesian locations, and Beculuk represents one stop along this intra-archipelago route. The cable enables inter-island data and communications exchange entirely within Indonesian territory.

Regional Context

Within Indonesia's submarine cable landscape, which spans 40 cables across 97 landing points, Beculuk ranks in the top 64% of landing points by cable count, hosting one cable. Major Indonesian hubs such as Batam (15 cables), Jakarta (7 cables), and Tanjung Pakis (7 cables) serve as far larger multi-cable convergence points, while Beculuk occupies a more focused role as a single-cable domestic terminus. Manado, Anyer, and Dumai, with five and three cables respectively, also handle greater cable volumes than Beculuk, reflecting the varied distribution of submarine cable infrastructure across the Indonesian archipelago.

Network Role

Beculuk functions as a single-cable terminus within Indonesia's domestic submarine cable network. Its connection through JaKa2LaDeMa links it to other Indonesian landing points along a 1,700 km intra-archipelago route, supporting inter-island connectivity without extending to international or intercontinental corridors. The cable's entirely domestic character means Beculuk's role is specifically oriented toward bridging distances between Indonesian islands rather than connecting Indonesia to foreign networks.

Within the broader Indonesian submarine cable graph, Beculuk represents one of 97 landing points distributed across the country's vast island chain, illustrating how Indonesia's cable infrastructure extends beyond its major urban hubs to serve more dispersed coastal locations through dedicated domestic cable systems.
