Ancol, Indonesia

Ancol, Indonesia: Submarine Cable Landing Point

Ancol is a coastal lowland area situated in northern Jakarta, Indonesia, lying between Kota Tua Jakarta to the west and Tanjung Priok to the east. Its position along the northern shoreline of Jakarta places it on one of Indonesia's most densely developed coastal stretches, and it serves as a submarine cable landing point for the country's domestic connectivity network. One submarine cable currently lands at Ancol, connecting it to another point within Indonesia.

The single cable landing here, Link 3 Phase-2, operates entirely within Indonesian territory, making Ancol a node in the country's intra-national submarine cable infrastructure rather than a gateway to international corridors. This domestic orientation reflects a strand of Indonesia's broader submarine cable development, in which inter-island links play a significant role alongside the country's many international connections.

Cables Landing at Ancol

Link 3 Phase-2 is a submarine cable with a total length of 342 km, which reached ready-for-service status in 2005 and is currently listed with draft status. The cable connects Ancol to another landing point within Indonesia, making it a domestic inter-island or coastal link. No other countries are served by this cable. No additional technical specifications, such as capacity or fiber pairs, are recorded for this system.

Regional Context

Within Indonesia's extensive submarine cable landscape — which encompasses 70 cables landing across 139 landing points — Ancol hosts a single cable, placing it in the top 62% of Indonesian landing points by cable count. Major Indonesian cable hubs such as Batam (20 cables), Jakarta (9 cables), and Tanjung Pakis (9 cables) host considerably more systems, reflecting their roles as principal gateways for both domestic and international traffic. Ancol's profile is more modest, consistent with its function as a localized domestic landing point rather than a regional hub.

Network Role

Ancol functions as a single-cable terminus within Indonesia's domestic submarine cable network. Through Link 3 Phase-2, it supports intra-Indonesian connectivity, contributing to the chain of inter-island and coastal links that bind together Indonesia's widely dispersed geography. The cable's 342 km length is well below the Indonesian average of 2,814 km, underscoring its role as a shorter-range domestic link rather than a long-haul international route.

As one of 139 landing points distributed across the Indonesian archipelago, Ancol represents the granular, localized layer of submarine cable infrastructure that complements the country's larger international gateways, illustrating how domestic inter-island systems extend connectivity beyond the major hub cities into the broader national network.
