Lake Ci, Taiwan: A Quiet Link Across the Strait

Lake Ci, Taiwan, is home to a single submarine cable, the Cross-Straits Cable Network (CSCN), which spans just 21 kilometers to connect Taiwan with China. While many of Taiwan's landing points host multiple cables-Toucheng has nine, Tanshui eight-Lake Ci stands apart as a smaller, quieter hub in Taiwan's submarine cable landscape. Its role is specific and focused: facilitating direct connectivity between Taiwan and China, a connection that carries both technical and geopolitical significance.

The Cross-Straits Connection

The CSCN, operational since 2012, links Lake Ci with three other landing points: Dadeng Island, Guanyin Mountain, and Guningtou. This cable is unique in its brevity-21 kilometers is far shorter than the average submarine cable length landing in Taiwan, which is over 7,200 kilometers. Its purpose is not to span oceans or continents but to provide a direct, high-speed link between two neighboring regions. This specialized role makes Lake Ci distinct from Taiwan's larger landing points, which often serve as gateways to global networks.

Regional Context: A Modest Player

Taiwan is a highly connected island, with 21 submarine cables landing at 21 points along its coastline. Major hubs like Toucheng and Tanshui host multiple cables, acting as critical nodes for international and domestic traffic. In contrast, Lake Ci, with just one cable, ranks in the top 62% of landing points in Taiwan by cable count. This modest presence reflects its specialized role rather than a lack of importance. While Lake Ci may not handle the same volume of traffic as larger hubs, its connection to the CSCN ensures it plays a key role in linking Taiwan with its closest neighbor.

Latency Insights: A Reliable Performer

GeoCables' own latency measurements reveal that Lake Ci performs consistently well. Across 42 completed checks from 12 source cities, the average round-trip latency to this landing point is 225 milliseconds, with the best observed latency an impressive 11 milliseconds. This low latency underscores the efficiency of the CSCN in handling cross-strait communications, ensuring that data moves quickly and reliably between Taiwan and China.

Lake Ci's Role in Taiwan's Network

While Lake Ci may not be a bustling hub of international connectivity, its single cable serves a clear purpose: maintaining direct communication with China. This connection complements Taiwan's broader network of 21 landing points, which collectively link the island to the world. Lake Ci's quiet presence in this network is a reminder that even smaller landing points play a meaningful role in the intricate web of global connectivity.
