Qingdao: Submarine Cable Landing Point

Qingdao is a prefecture-level city in the eastern Shandong Province of China, situated on the Shandong Peninsula and facing the Yellow Sea. Its coastal position on the Yellow Sea has made it a natural point of entry for submarine cable infrastructure connecting China to the broader Asia-Pacific region. Two submarine cables land at Qingdao, linking the city to a wide arc of economies spanning Northeast Asia, Southeast Asia, and the United States.

The two cables landing here — EAC-C2C and the Trans-Pacific Express (TPE) Cable System — together establish Qingdao as a node within both intra-regional and transoceanic submarine cable corridors. EAC-C2C connects countries across Northeast and Southeast Asia, while TPE extends Qingdao's reach directly across the Pacific to the United States, enabling a transoceanic route from this Yellow Sea coastline.

Cables Landing at Qingdao

EAC-C2C is a submarine cable system with a total length of 36,500 km that reached ready-for-service (RFS) status in 2002. It connects landing points across China, Japan, the Philippines, Singapore, South Korea, and Taiwan. At 36,500 km, EAC-C2C is one of the longer cable systems in the region, spanning a broad loop through Northeast and Southeast Asian waters and linking Qingdao into a multi-country intra-Asian network.

Trans-Pacific Express (TPE) Cable System has a total length of 17,968 km and reached RFS in 2008. TPE connects China, Japan, South Korea, Taiwan, and the United States. The cable represents a direct transoceanic link from Qingdao to the United States, passing through several intermediate East Asian economies. Its 2008 RFS date places it among the earlier generation of transpacific cable systems serving China's northern coast.

Regional Context

Within China's submarine cable geography — which encompasses 24 landing points — Qingdao's two cables place it among the more modestly connected sites. Leading Chinese landing points such as Chung Hom Kok and Tseung Kwan O each host six cables, while Chongming and Nanhui each host four, and Shantou hosts three. Qingdao shares its two-cable count with Lantau Island, and sits in the top 79% of Chinese landing points by cable count.

Network Role

Qingdao functions as a two-cable landing hub serving both regional and transoceanic routing. EAC-C2C anchors it within a Northeast and Southeast Asian circuit touching Japan, South Korea, Taiwan, the Philippines, and Singapore, while TPE adds a direct Pacific crossing to the United States. Together, the two cables give Qingdao access to five distinct foreign country markets — Japan, South Korea, Taiwan, the Philippines, Singapore, and the United States — from a single coastal location on the Yellow Sea.

While Qingdao is not among the highest-density cable landing points in China, its combination of a long-haul intra-Asian cable and a transpacific system means the Yellow Sea coastline of Shandong Province participates in both the regional East Asian submarine cable mesh and the broader Pacific intercontinental layer — a pairing that distinguishes it from single-cable terminus sites elsewhere in the Chinese network.
