Sanana, Indonesia: Submarine Cable Landing Point

Sanana is a town on Sulabesi Island and the administrative center of Sula Islands Regency, in the North Maluku province of Indonesia. As an island community within one of the world's largest archipelago nations, Sanana depends on submarine cable infrastructure to maintain connectivity with the broader Indonesian network. Two submarine cables land at Sanana, linking it into the domestic cable fabric of Indonesia.

Both cables serving Sanana connect exclusively to other points within Indonesia, making this landing point a node within a domestic inter-island connectivity framework. The cables — SMPCS Packet-1 and Palapa Ring Middle — represent distinct systems built at different periods and together form the basis of Sanana's submarine cable presence.

Cables Landing at Sanana

SMPCS Packet-1 is a submarine cable system measuring 3,156 km in length, with a ready-for-service (RFS) date of 2015. All endpoints on this cable are located within Indonesia, placing it firmly in the category of a domestic inter-island system. It extends connectivity across multiple Indonesian locations, with Sanana serving as one of its landing points along the route.

Palapa Ring Middle is a submarine cable system measuring 2,100 km in length, with an RFS date of 2018. Like SMPCS Packet-1, all other countries connected by this cable are within Indonesia. The Palapa Ring Middle system forms part of Indonesia's nationally coordinated initiative to extend submarine cable connectivity across its island territories, and Sanana sits among its landing points as part of that broader domestic network design.

Regional Context

Within Indonesia's extensive submarine cable landscape — which encompasses 70 cables across 139 landing points — Sanana ranks in the upper 85% of Indonesian landing points by cable count, hosting 2 cables. This places it well behind major hubs such as Batam (20 cables), Jakarta (9 cables), and Makassar (6 cables), but Sanana's role is specifically oriented toward serving island communities in the eastern Indonesian archipelago rather than functioning as a large international or regional interchange point.

Network Role

Sanana functions as a multi-cable domestic landing point, connected by two separate Indonesian inter-island systems. The combination of SMPCS Packet-1 and Palapa Ring Middle gives the town a degree of cable redundancy that many smaller Indonesian island communities do not possess. Both systems operate entirely within Indonesian territory, meaning Sanana's submarine cable connections support intra-archipelago communication rather than international routing.

In the broader Indonesian submarine cable graph, Sanana represents the kind of secondary node that extends the national network into more remote island communities in the eastern reaches of the country. Its position within two distinct domestic cable systems — one from 2015 and one from 2018 — reflects successive efforts to connect outlying Indonesian territories to the country's growing terrestrial and submarine communications infrastructure.
