Adtran, Inc. is an American fiber networking and telecommunications company headquartered in Huntsville, Alabama. It is a vendor of both residential and enterprise networking equipment, along with administrative software for network management and deployment. Its customers include communications service providers, governments, enterprises and utilities.

History

[edit]

Adtran was founded in 1985 by Mark C. Smith,[5] Lonnie S. McMillian,[6] and Larry Owen, and began operations in 1986, following the AT&T divestiture of the Regional Bell Operating Companies (RBOCs). It supplied network equipment to both the RBOCs and independent telephone companies in the United States.[7]

In 2006, Adtran acquired Luminous Networks, a manufacturer of access network equipment. In 2011, it acquired Bluesocket, a maker of enterprise Wi-Fi equipment based in Burlington, Massachusetts. In 2012, it acquired Nokia Siemens Networks' broadband access business based in Germany. In 2016, it acquired CommScope's active fiber business.[8][9] In 2018, Adtran acquired connected home software provider SmartRG from Vancouver, WA.[10]

In 2021, Adtran entered into a business combination with ADVA Optical Networking, a cloud and mobile services networking company based in Munich and Meiningen in Germany.[11] In 2022, Adtran acquired the remaining shares of Cambridge Communication Systems (CCS) Limited, a developer of wireless backhaul and transport systems for small cells. It offers an mmWave Gigabit fiber extension system along with web-based management software for planning, configuring and monitoring networks. In 2024, Adtran self-certified itself "Buy America-compliant" with the U.S. Department of Commerce. This list acts as a reference for communications service providers applying for Broadband Equity Access and Deployment (BEAD) funding.[12]

Notable products

[edit]

50G PON: Adtran's implementation of 50Gbit/s passive optical network (PON) technology includes its SDX 6400 Series of optical line terminals.

Quantum key distribution (QKD): In collaboration with Orange, Adtran demonstrated a 400Gbit/s data transmission system using QKD. The hybrid approach integrated quantum-safe encryption with classical cryptographic methods to secure data across a 184 km system.

Optical cesium atomic clocks: Adtran's Oscilloquartz division has introduced atomic clocks that leverage optical pumping technology. The improved accuracy and stability of these devices exceed the current ITU-T G.811.1 Enhanced Primary Reference Clock (ePRC) specification. The current highest-end clocks in this range can combine with core grandmaster devices to maintain 100 nanosecond precision for up to 100 days.

Mosaic One: Mosaic One is a cloud-based software-as-a-service platform that aggregates data from management systems, broadband access and in-home devices to support network operations and customer care.
