Selayar: A Singular Connection in Indonesia's Submarine Cable Network

Selayar, a picturesque island located in South Sulawesi Province, Indonesia, is home to one submarine cable landing point. While it may not boast the dense connectivity of major hubs like Batam (20 cables) or Jakarta (10 cables), Selayar plays a unique role in Indonesia's sprawling cable network. The solitary cable landing here - the Indonesia Tengah Cable Systems - stitches Selayar into a broader web of domestic connectivity, linking it to nine other landing points across the archipelago.

The Indonesia Tengah Cable Systems: A Domestic Lifeline

The Indonesia Tengah Cable Systems, set to be ready for service in 2027, spans 2641 kilometers and connects Selayar to other Indonesian locations, including Makassar, Baubau, and Wakatobi. This cable does not extend internationally, focusing instead on strengthening regional communication within Indonesia. For Selayar, this connection represents a concrete step toward better integrating the island into the nation's digital and economic framework. Selayar's neighbors in the cable chain are diverse, ranging from bustling cities like Makassar, which hosts six cables, to smaller, more remote areas like Wakatobi. This network ensures that even Indonesia's lesser-connected regions benefit from improved communication and data transfer capabilities. While Selayar may not rival larger hubs in cable density, its inclusion in this chain highlights Indonesia's commitment to bridging the digital divide across its islands.

Geography Meets Connectivity

Selayar Island is separated from the mainland by the Selayar Strait, a waterway dotted with smaller islands like Kambing Island and Pulau Pasitanete. The strait is navigable by ferry, underscoring the logistical challenges of connecting such remote areas. The arrival of the Indonesia Tengah Cable Systems will complement these physical connections, bringing faster and more reliable digital access to Selayar's residents.

Latency Insights: Measuring Selayar's Digital Pulse

GeoCables' unique latency monitoring reveals an average round-trip latency of 290 milliseconds for connections to Selayar, with the best observed latency at 205 milliseconds. While these figures may not match the ultra-low latencies of Indonesia's major hubs, they represent a significant improvement for an island that relies heavily on domestic cable infrastructure.

Positioning Selayar in Indonesia's Cable Landscape

Indonesia hosts a total of 70 submarine cables across 139 landing points, with Selayar ranking in the top 62% by cable count. While its single cable pales in comparison to the dense networks of Batam or Jakarta, Selayar's inclusion in the Indonesia Tengah Cable Systems chain ensures it is not left behind in the nation's digital evolution. For Selayar, this cable is not just a technical achievement - it is a bridge to greater opportunities for communication, commerce, and connectivity. As Indonesia continues to expand its submarine cable infrastructure, landing points like Selayar demonstrate the importance of connecting even the most remote corners of this vast archipelago.
