Adtran (ADTN) launched Mosaic One Agents, a suite of AI agents for network management, customer care and business operations. Built on Mosaic One Fabric, the suite gives role-based agent teams access to data from Adtran and third-party networks. Adtran says the agents can investigate issues and coordinate workflows in parallel under human direction.
Users can set autonomy levels, from recommendations to actions staged for approval or work within predefined boundaries. Organizations can deploy Adtran agents, create their own or combine both approaches.
Adtran (ADTN) will demonstrate its open optical networking solutions in OIF’s live multi-vendor interoperability demo at ECOC 2026 in Málaga, Spain, from September 21–23, 2026.
The company is supplying 100Gbit/s, 400Gbit/s and 800Gbit/s ZR+ pluggable coherent transceivers, its FSP 3000 open line system operating across C- and L-bands, and Mosaic Network Controller software for hierarchical control. Adtran also hosted the OIF interoperability test run at its labs in Gdynia, Poland, helping participating vendors validate integrations ahead of the show.
Adtran (ADTN) is supplying packet edge technology to expand BMC TV’s UK core network for major live sports broadcasts, including the FIFA World Cup and racecourse coverage. The upgraded infrastructure enhances BMC TV’s packet edge, access and aggregation layers to distribute live feeds across multiple locations with deterministic, low-latency performance and 100Gbit/s Ethernet services.
Built on Adtran’s FSP 150 switching and routing portfolio and orchestrated by Mosaic Network Controller with Packet Director, the platform can be rapidly reconfigured between events and venues and is designed to scale toward future 400Gbit/s services. The deployment was designed and implemented in partnership with Fibre Technologies Ltd.
Adtran (NASDAQ: ADTN) and GOCare announced that Telephone Electronics Corporation (TEC) is using GOCare’s OutageIQ, integrated with Adtran’s outage notification API and Mosaic One, to automate outage communications. TEC serves fiber broadband subscribers across Mississippi, Alabama and Tennessee.
The solution leverages real-time network and subscriber data to trigger proactive SMS and voice notifications when issues are detected, reducing inbound support calls and giving TEC’s support teams better context. According to Adtran, the open API approach enables providers to embed proactive workflows into existing systems. The joint deployment was named a finalist for the 2026 Fiber Broadband Association Constellation Award.
Adtran (NASDAQ: ADTN) launched Mosaic One Fabric, an expansion of its Mosaic One software platform designed to let network operators create, govern and scale their own AI agents and workflows around specific operational priorities. The platform aims to avoid vendor lock-in by supporting operators’ choice of data, tokens and AI models, with token economics visible and under operator control.
Mosaic One Fabric exposes network, operational data and telecom expertise as reusable, MCP-based, agent-ready tools and adds guardrails so AI agents interact safely with multi-vendor networks and business domains. Adtran is also extending integration, workflow design and advisory services to help operators deploy AI-driven operations at scale.
Adtran (NASDAQ: ADTN) announced that TOHKnet has completed Japan’s first live network trial showing the coexistence of 50G PON, XGS-PON and EPON on a single fiber in Sendai.

According to Adtran, the trial illustrates a practical migration path for Japanese operators to introduce 50G PON capacity while maintaining continuity for existing services and avoiding major changes to the optical distribution network. The SDX 6400’s modular architecture is designed to let operators align upgrades with customer demand, support enterprise service continuity, and maximize the value of existing regional fiber assets.
