Alcatel Submarine Networks

What Alcatel Submarine Networks does

Alcatel Submarine Networks (ASN) is a French-headquartered, Nokia-owned provider of turnkey submarine fiber optic cable systems, founded in 1994 and based in Nozay, France with manufacturing facilities in Calais (France) and Greenwich (United Kingdom). The company designs, manufactures, installs, and maintains submarine cable infrastructure spanning telecommunications, offshore energy, and distributed acoustic sensing applications. Since inception ASN has deployed over 850,000 km of submarine optical systems globally, equivalent to circling the globe 21 times, and operates a dedicated marine fleet of 7 cable vessels for installation and maintenance operations.

ASN's core technology portfolio centers on the XBU 24FP 24-fiber-pair repeater system — the world's first operational 24-fiber-pair repeatered submarine cable, enabling each fiber pair to carry more than 26 Tbps and total system capacity above 624 Tbps — and OptoDAS, an advanced distributed acoustic sensing interrogator that converts more than 100 km of submarine cable into an acoustic antenna for cable threat monitoring and scientific applications. The product portfolio is organized across Telecommunications, Energy Solutions, Fiber Sensing (DAS), Services (O&M across the network lifecycle), and Upgrade (capacity enhancement for existing systems).

ASN operates a project-based B2B business model selling large-scale infrastructure to telecom operators, content/cloud providers, governments, and offshore energy operators via direct enterprise sales and competitive tenders. Revenue is generated through one-time project contracts (cable design, manufacturing, installation) supplemented by recurring lifecycle services including operations and maintenance and system upgrades. Notable customers include Sparkle, Ooredoo Group, center3 (stc group), du, AFR-IX Telecom, Mobily, FastWeb, EllaLink, Unitirreno, and the Governments of Mauritania and Timor-Leste. Pricing is quote-based and project-specific; no standardized pricing tiers are publicly disclosed. ASN is led by President & CEO Alain Biston and operates as a private strategic subsidiary of Nokia.
