Anyer, Indonesia

Anyer: Submarine Cable Landing Point

Anyer is a coastal town in Banten province, Indonesia, situated on the Sunda Strait approximately 100 kilometres west of Jakarta. As a submarine cable landing point, Anyer hosts three submarine cables, placing it among the more connected landing sites along Indonesia's western coastline. The cables landing here span both international and domestic routes, with the international connection reaching as far as Australia and Singapore.

The presence of the Australia-Singapore Cable (ASC) at Anyer positions the town as a point on one of the key intercontinental corridors linking Southeast Asia with Australia. Alongside this international system, two domestic cables — SJJK and BNCS-1 — extend Anyer's connectivity within the Indonesian archipelago.

Cables Landing at Anyer

The Australia-Singapore Cable (ASC) is an international submarine cable system measuring 4,600 kilometres in length, which entered service in 2018. In addition to Anyer in Indonesia, the ASC connects to Australia, Christmas Island, and Singapore, forming a route that spans the eastern Indian Ocean and the waters between the Australian continent and the Singapore hub.

The SJJK cable is a domestic Indonesian system measuring 543 kilometres, which entered service in 2008. Both of its endpoints are within Indonesia, making it a purely intra-national cable that links Anyer to another Indonesian location.

The Biznet Nusantara Cable System-1 (BNCS-1) is a domestic submarine cable measuring 105 kilometres, which entered service in 2024. Like SJJK, both of its endpoints are within Indonesia, extending Anyer's role in connecting locations across the Indonesian island chain.

Regional Context

Within Indonesia's submarine cable network — which spans 70 cables across 139 landing points — Anyer ranks in the top 93 percent of landing points by cable count. Compared to major Indonesian cable hubs such as Batam (20 cables), Jakarta (9 cables), and Tanjung Pakis (9 cables), Anyer is a smaller but notable node, distinguished in particular by its hosting of the intercontinental ASC system. Its three-cable complement places it above the national average for Indonesian landing points.

Network Role

Anyer functions as a multi-cable landing point serving both intercontinental and domestic routing purposes. The ASC system connects Anyer to Singapore and Australia, enabling traffic flow along the Australia–Southeast Asia corridor, while Christmas Island is also served along this route. The two domestic cables, SJJK and BNCS-1, extend Anyer's role as a node within Indonesia's internal submarine cable infrastructure, contributing to intra-archipelago connectivity.

With three cables of differing scales — one long-haul international system and two shorter domestic links — Anyer occupies a distinct position in the regional submarine cable graph as a point where international and domestic Indonesian routes converge on the Sunda Strait coast.
