Alcatel Submarine Networks (ASN) is a French company and one of the three world leaders in the manufacture and installation of submarine cables. It was a subsidiary of Alcatel, then Alcatel-Lucent, until it was acquired by the Finnish group Nokia in 2016. It was owned by Nokia France from 2016 to 2024. The French state acquired 80% of the company's capital in November 2024.
Alcatel Submarine Networks designs, manufactures, lays and maintains telecommunications submarine cables and related equipment, using its own vessels to carry optical fibre around the globe. Laying telecommunications submarine cables is a strategic industry. ASN, Subcom and NEC dominate this global market, with 99% of Internet traffic passing through these cables, 80% of which transits through the United States, whatever its destination. In 2018, ASN's market share (30%) was ahead of Japanese competitor NEC (23%) and American Subcom (20%).
As of 2024, ASN has 2,000 employees, including 1,370 in France. The company has several sites in France, the United Kingdom and Norway. Alcatel Submarine Networks has a fleet of seven cable-laying vessels and is the world No. 1 in the sector.
