Yantai, China: Submarine Cable Landing Point

Yantai is a coastal prefecture-level city situated on the Shandong Peninsula in China, lying on the southern coast of the Bohai Strait with sea access to both the Bohai Sea and the Yellow Sea. This coastal position makes it a natural site for submarine cable infrastructure connecting points across the enclosed and semi-enclosed waters of northern China. One submarine cable lands at Yantai, linking it directly to the city of Dalian across the Bohai Strait in a domestic, intra-China corridor.

The single cable serving Yantai establishes a regional, short-haul connection between two significant cities on opposite shores of the Bohai Strait. Rather than forming part of an intercontinental route, the Yantai landing point functions within a domestic Chinese network context, providing a direct undersea link across a busy maritime passage.

Cables Landing at Yantai

The Dalian-Yantai Cable is the sole submarine cable landing at Yantai. Spanning approximately 146 kilometres, the cable connects Yantai on the Shandong Peninsula to Dalian in Liaoning Province, both located within China. The cable reached ready-for-service status in 1998 and was one of the early submarine cable deployments in China, given that the country's first submarine cable came into service in 1997. Its relatively short length reflects its function as a cross-strait domestic link rather than a long-distance international connection.

Regional Context

Within China's submarine cable landscape, which encompasses 24 cables landing across 24 landing points, Yantai hosts a single cable and ranks within the top 63 percent of Chinese landing points by cable count. Major Chinese landing points such as Chung Hom Kok and Tseung Kwan O each host six cables, while Chongming and Nanhui host four, and Shantou hosts three. Yantai's single-cable profile places it among the more modestly served landing points in China, reflecting its role as a domestic rather than international cable hub.

Network Role

Yantai functions as a single-cable terminus rather than a multi-cable hub, serving the specific corridor across the Bohai Strait between the Shandong and Liaoning coasts. The Dalian-Yantai Cable enables a direct undersea path between these two provincial cities, complementing overland and ferry routes across the strait with a dedicated submarine connection. The cable's domestic scope means Yantai does not participate in international submarine cable routes.

In the broader submarine cable graph of China, Yantai represents an example of targeted domestic connectivity, where a relatively short cable addresses the geographic separation imposed by a narrow but significant body of water. Its presence demonstrates that submarine cable infrastructure in China extends beyond major international gateways to serve intra-national routing needs across coastal straits.
