Friedrichshafen is a city situated on the northern shore of Lake Constance in the federal state of Baden-Württemberg, southern Germany, close to the borders of both Switzerland and Austria. As a landing point for submarine cable infrastructure, Friedrichshafen hosts one submarine cable that crosses the waters of Lake Constance, connecting it to another point on the same lake. The cable landing here is the Konstanz-Friedrichshafen cable, a short freshwater lake crossing that links two German cities on the shores of Lake Constance.
The connectivity enabled by Friedrichshafen's cable infrastructure is intra-national in character, forming a direct link between two German lakeside communities rather than an intercontinental or cross-border route. Lake Constance, bordered by Germany, Switzerland, and Austria, provides the geographic context for this short but purposeful cable crossing. Friedrichshafen's position on the northern shore of Lake Constance makes it a natural anchor for such a regional, intra-lake connection.
The Konstanz-Friedrichshafen cable is the single submarine cable landing at Friedrichshafen. With a length of 26 km, it is a notably short cable by submarine standards, reflecting its role as a lake crossing rather than an open-sea route. The cable reached ready-for-service (RFS) status in 2007, with its draft status noted at that time. Both endpoints of this cable lie within Germany, with Konstanz serving as the other landing point. The cable thus forms a direct underwater link between two German cities on Lake Constance.
Within Germany's network of submarine cable landing points, Friedrichshafen hosts one cable, placing it alongside Markgrafenheide, Meersburg, and Puttgarden as single-cable landing points. Germany has ten submarine cables distributed across nine landing points, with Rostock leading at three cables, followed by Konstanz and Wilhelmshaven with two cables each. Friedrichshafen ranks within the top 67 percent of German landing points by cable count, consistent with the modest scale typical of inland lake cable crossings.
Friedrichshafen functions as a single-cable terminus, with the Konstanz-Friedrichshafen cable providing a direct underwater link across Lake Constance to the city of Konstanz. This connection is entirely within German territory, enabling a regional, intra-lake data path rather than a gateway to international submarine networks. The cable's short length of 26 km reflects the geographic scale of Lake Constance rather than the longer open-sea spans characteristic of most German submarine cable landings, where the average cable length is 1,480 km.
Within the broader German submarine cable graph, Friedrichshafen represents a specialized node oriented toward intra-national lake connectivity. Its pairing with Konstanz — itself a two-cable landing point — means that the Konstanz-Friedrichshafen cable contributes to a small but distinct cluster of Lake Constance infrastructure, differentiating the southern German inland lake corridor from the North Sea and Baltic Sea routes that characterize most of Germany's other submarine cable landings.
