Xtera

What Xtera does

Xtera is a UK-headquartered provider of submarine fiber optic cable systems and turnkey project delivery services, founded in 1998 and operating primarily in the subsea telecommunications infrastructure market. The company designs, manufactures, and commissions both repeatered (with underwater hybrid Raman/EDFA optical amplifiers) and unrepeatered subsea cable networks, with installations across more than 60 countries on five continents and a portfolio covering 21 repeatered plus 14 unrepeatered system awards.

Core products include Repeater Units (hybrid Raman/EDFA, C and C+L band, up to 70 nm optical bandwidth, 8,000 m depth rating, 2 to 24 fiber pair configurations), Branching Units with supervisory-controlled power switching, the Nu-Wave Optima modular terminal platform (supporting QPSK to 32QAM modulation and variable baud-rates), an Open System Gateway that monitors and controls submerged plant from multiple vendors, a Network Management System, and XteraCare aftersales support packages. Technical milestones include demonstrated 1.3 Tbit/s per fiber pair on the Americas 1 North upgrade (a 500x capacity uplift over the original 2.5 Gb/s design), 100 Gbit/s over 627 km unrepeatered spans, and industry-leading 24 fiber pair Space Division Multiplexing (SDM) repeater deployment, complemented by research records with University College London (74.38 Tbit/s over 6,300 km and 120 Tbit/s over a single repeatered fiber).

The business model is project-based turnkey EPC contracting alongside standalone equipment sales and recurring capacity-upgrade services. Customers are large telecom operators, US and allied government/defense agencies (notably the US Department of Defense), and submarine cable system developers, with representative projects including TAM-1 ($65M, AT&T/Trans Americas Fiber System anchor), Nome to Homer Express ($77M, Quintillion), Galapagos Cable System (1,280 km), NO-UK (700 km), and Americas 1 North. Distribution is asset-light through a partner ecosystem: cable from Nexans and Prysmian/NSW, marine installation from Global Marine, Orange Marine, and IT International Telecom, and components from Spellman and STI. The company was acquired by H.I.G. Capital in February 2017, was being sold to a Prysmian S.p.A. (80%) and Fincantieri S.p.A. (20%) joint venture for approximately €55.2 million (~$65M enterprise value) in December 2025, and operates from London (headquarters, R&D, cleanroom manufacturing) with engineering offices in Allen, Texas and a McKinney, Texas office.

Scale indicators13 records

Recent moves8 records

Expansion highlights6 records

Direct peers

• Alcatel Submarine Networks (ASN): ASN is the dominant global supplier of turnkey submarine cable systems and wet plant (repeaters, branching units). It is Xtera's primary direct competitor for greenfield submarine projects and the historical employer of much of Xtera's leadership team.
• NEC Submarine Networks: NEC is a leading supplier of submarine cable systems with end-to-end capabilities including wet plant, terminal equipment, and marine installation. It directly competes with Xtera on large transoceanic and regional cable builds.
• TE Subcom (SubCom): SubCom is a U.S.-based turnkey submarine cable system provider serving hyperscalers and telcos. It competes head-to-head with Xtera on greenfield projects and capacity upgrades across the Atlantic and Pacific.

Emerging players

• HMN Technologies: HMN Tech (formerly Huawei Marine) builds and installs submarine cable systems globally. It overlaps with Xtera on turnkey wet-plant projects and has emerged as a credible alternative bidder on emerging-market cable builds.
• ADVA Optical Networking: ADVA licensed Xtera's optical technology in 2018 to enhance its own transport products. It is a technology and integration partner with overlapping capabilities in optical amplification for terrestrial and subsea applications.

Broad incumbents

• Prysmian Group: Prysmian is the world's largest cable manufacturer, including submarine fiber optic cable, and Xtera's acquiring parent (80% stake via JV with Fincantieri). It is both a strategic partner on cable supply and a vertically adjacent competitor in wet-plant project delivery.
• Nexans: Nexans is a major submarine cable manufacturer supplying wet plant to Xtera's TAM-1 and other turnkey projects (Rognan facility). It is an established partner but also competes with Xtera in adjacent cable system integration.
• Ciena: Ciena supplies submarine line terminal equipment (SLTE) and coherent optical technology widely used on submarine cable networks. Xtera's VP of Engineering came from Ciena, and the two are interoperable via Xtera's open-architecture gateway.

Others

• Hexatronic: Hexatronic is a fiber optic infrastructure supplier that contributed content to Submarine Telecoms Forum alongside Xtera. It is an adjacent ecosystem participant with submarine cable component exposure rather than a direct turnkey competitor.
• Global Marine Systems Limited: Global Marine is one of Xtera's strategic marine installation partners (e.g., NO-UK cable). It is a critical enabler of Xtera's turnkey delivery rather than a competitor in wet-plant design and supply.
