Jincheng Township, Taiwan: Submarine Cable Landing Point

Jincheng Township is an urban township located on the southwestern corner of Kinmen Island (also known as Quemoy), serving as the county seat of Kinmen County in Taiwan. As an offshore island community situated at a distance from Taiwan's main island, Jincheng Township is connected to the broader national telecommunications network through submarine cable infrastructure. One submarine cable lands at this location, linking Kinmen to other parts of Taiwan's island group.

The single cable landing at Jincheng Township operates entirely within Taiwan's domestic network, connecting the outlying islands administered by Taiwan rather than bridging intercontinental or international corridors. This reflects the particular geographic challenge of maintaining reliable connectivity between Taiwan's main island and its more distant island communities, including Kinmen, Penghu, and Matsu.

Cables Landing at Jincheng Township

Taiwan Penghu Kinmen Matsu No.3 (TPKM3) is a 510-kilometre submarine cable that reached ready-for-service status in 2013 as a draft system. The cable connects multiple island groups administered by Taiwan, with all endpoints located within Taiwan. As its name indicates, the system links Taiwan's main island with the outlying island groups of Penghu, Kinmen, and Matsu, providing domestic inter-island connectivity across Taiwan's geographically dispersed territories.

Regional Context

Within Taiwan's submarine cable landscape, Jincheng Township ranks among the smaller landing points by cable count, hosting one cable out of the 21 submarine cables that land across Taiwan's 21 landing points. Major landing points such as Toucheng and Tanshui host nine and eight cables respectively, while Dongyin hosts three, and Dawu, Fangshan, and Huxi Township each host two. Jincheng Township's single-cable presence reflects its role as a terminal serving a specific outlying island community rather than a multi-cable convergence point.

Network Role

Jincheng Township functions as a single-cable terminus within Taiwan's domestic inter-island submarine cable network. The TPKM3 system landing here is oriented specifically toward connecting Taiwan's offshore island communities—Kinmen among them—to the national telecommunications fabric, enabling intra-country data and communications links across island groups that cannot be served by terrestrial infrastructure.

In the broader submarine cable graph of Taiwan, Jincheng Township occupies a specialised position: it is not a hub for international traffic, but rather a dedicated endpoint ensuring that the residents and institutions of Kinmen Island maintain a submarine cable connection to the rest of Taiwan's networked territories. This role, while narrow in scope, represents a distinct node in the domestic inter-island connectivity architecture that Taiwan maintains across its dispersed island geography.
