Xtera Communications is a developer and supplier of advanced optical transport solutions for terrestrial and submarine networks. The company specializes in coherent optical transmission systems and submarine line terminal equipment that enable service providers, cable operators and research networks to scale bandwidth over existing and new fiber infrastructure. Leveraging proprietary coherent modulation techniques, Xtera’s products support high-capacity, long-haul transmission in harsh undersea environments as well as in metropolitan and long-distance terrestrial backhaul applications.
The company’s core product portfolio includes submarine line terminal equipment, optical amplifiers, space-division multiplexing solutions, and integrated management software. Xtera’s submarine line terminal systems are designed to interface with repeaters and branching units in deep-sea cable systems, delivering channel capacities suited to intercontinental links. On land, Xtera offers compact rack-mounted transport platforms that enable carriers to deploy dense wavelength-division multiplexing (DWDM) over existing fiber routes. Complementary services such as network planning, system integration, commissioning and 24/7 technical support help customers bring new routes online and optimize ongoing performance.
Xtera serves a global customer base spanning telecommunications operators, subsea cable consortiums, research and education networks, and hyperscale data center operators. The company’s solutions have been deployed in major subsea projects linking North America, Europe, Asia and Africa, as well as in strategic terrestrial corridors in the Americas, the Middle East and Asia-Pacific region. With regional offices and certified integration partners worldwide, Xtera supports customers from initial feasibility studies through system upgrades and lifecycle maintenance.
Founded in the late 1990s and headquartered in California, Xtera has grown through a combination of in-house innovation and strategic partnerships. Early recognition of the potential for coherent optical transmission in submarine environments positioned the company as a pioneer in next-generation cable system design. Today, Xtera is led by CEO Michael Friedman, whose executive team combines expertise in optical networking, subsea engineering and global project delivery. Under this leadership, the company continues to advance high-capacity transport technologies to meet the evolving needs of operators and content providers around the world.
