    STRUCTURE


    To ensure the highest levels of reliability, quality and standards compliance, ASN designs and manufactures all of its own cables as well as its dry plant and wet plant components.

    ASN is a vertically integrated supplier with a unique positioning in system integration covering all components and activities – research, engineering, manufacturing, installation – offering customized and optimized turnkey solutions for each project.

    A fleet of 6 cable ships for installation and maintenance – Ile de Sein, Ile de Batz, Ile de Bréhat, Ile d’Aix, Lodbrog, Peter Faber – and associated equipment (ROV and ploughs) is owned by ASN. The fleet is managed by the French company Louis-Dreyfus Armateurs.

    Manufacturing and innovation capabilities:

    • Calais, France:This site was created in 1891 and hosts R&D and manufacturing activities, offering the largest manufacturing capability in the industry (45,000 km of cable per year). At this site, ASN also performs cable R&D and the recycling of out of service cables.
    • Greenwich, UK: Amplifiers, repeaters, branching units, ROADM and other submerged equipment are produced at this site where the world’s first transatlantic cable was manufactured in 1858. Today, the site houses modern production and clean room facilities, SLTE and PFE assembly and testing, as well as office space for project management and marine operations teams.
    • Paris-Saclay (Essonne - France):The ASN headquarters which hosts R&D, commercial and technical teams, as well as support functions. In our design laboratories in Paris Saclay, we have more than 25,000 km of optical fiber and associated optical amplifiers. These resources allow our technical teams to create test systems for next-generation networks and to replicate deployed submarine cable systems to validate capacity upgrades.
    • Trondheim, Norway: Part of ASN since November 2014, this site hosts R&D and manufacturing activities for seismic sensors and analogic systems.

    A worldwide reach with commercial presence in France, UK, US, China, Australia and Norway.
