Port Gentil, Gabon: Submarine Cable Landing Point

Port Gentil is Gabon's second-largest city, situated on a delta island in the Ogooué delta along the Atlantic coast of Central Africa. As a leading seaport and the center of Gabon's petroleum and timber industries, the city occupies a distinct geographic position, with nearby Cape Lopez marking Gabon's westernmost point. One submarine cable lands at Port Gentil, connecting it directly to the national submarine cable network.

The single cable serving Port Gentil operates entirely within Gabon, linking the city to the capital, Libreville, along the country's Atlantic coastline. This makes Port Gentil a domestic terminus within Gabon's submarine cable infrastructure, rather than a gateway to intercontinental or inter-regional routes. The connection it provides is a coastal, intra-national link between Gabon's two principal populated centers.

Cables Landing at Port Gentil, Gabon

The Libreville-Port Gentil Cable is the sole submarine cable landing at Port Gentil. Spanning 198 kilometers, this cable was ready for service in 2012 and connects Port Gentil to Libreville, with both endpoints located within Gabon. The cable operates as a domestic coastal link, running entirely within Gabonese territorial waters along the Atlantic seaboard.

Regional Context

Within Gabon, Port Gentil is one of two submarine cable landing points, the other being Libreville. Libreville hosts five submarine cables, making it by far the more connected of the two cities in terms of submarine cable infrastructure. Port Gentil's single cable connects it exclusively to Libreville, positioning it as a secondary landing point that depends on Libreville for any onward international connectivity.

Network Role

Port Gentil functions as a single-cable domestic terminus in Gabon's submarine cable network. Its one landing, the Libreville-Port Gentil Cable, provides a direct subsea link between the country's two largest cities, routing connectivity across the delta geography that separates Port Gentil from the mainland. The city does not independently terminate any international submarine cable, meaning that traffic originating in or destined for Port Gentil reaches the broader global network through Libreville's more extensive cable infrastructure.

In the regional submarine cable graph, Port Gentil's role is that of a coastal extension point, broadening the geographic reach of Gabon's cable network to include the country's primary Atlantic port city. Its position illustrates how domestic submarine cables can serve an important function in connecting island-situated or delta-located cities that are otherwise physically separated from a country's main cable hub.
