Adtran (NASDAQ:ADTN) was selected by FiberCop to supply optical transport for a nationwide metro rollout in Italy to support the operator's open-access strategy. The deployment uses Adtran's FSP 3000 platform (AccessFlex, M-Flex800), Coherent 100ZR pluggables for compact 100G metro links, and the Mosaic Network Controller for centralized management and automation. The solution supports 100G and 400G DWDM and emphasizes space-, cost- and power-efficiency across major Italian cities.
Adtran (NASDAQ:ADTN) said Henderson Municipal Power & Light is expanding citywide broadband in Henderson, Kentucky using Adtran’s open intelligent fiber access platform to deliver multigigabit FTTH. The deployment uses XGS-PON access with SDX 6330 and SDX 8305 OLTs, 630 Series ONTs and 8600/8700 mesh Wi‑Fi gateways, integrated with Mosaic One and GLDS BroadHub® for simplified operations, faster provisioning and flexible billing.
Adtran also highlighted AI-driven insights and Intellifi connected‑home features to improve reliability, reduce support costs and drive subscriber engagement and ARPU.
Adtran (NASDAQ:ADTN) announced on November 18, 2025 that ACE Fiber, the broadband unit of ACE Power in Mississippi, deployed Adtran’s Mosaic One Clarity powered by the REAL AI platform to move from reactive troubleshooting to proactive assurance.
The solution consolidates access and in-home metrics, identifies likely root causes, prioritizes guided actions, and aims to reduce truck rolls. Early results show up to 75% fewer trouble tickets in the first month, faster fault resolution and improved customer experience. The deployment is designed to scale as ACE Fiber adds data sources and policies, supporting phased AI adoption without retooling.

NextNav (Nasdaq: NN) and Oscilloquartz announced successful integration of NextNav 5G-based PNT (Positioning, Navigation, and Timing) technology with an Oscilloquartz GNSS-enabled grandmaster clock on October 24, 2025.
The combined system produced GPS-quality timing outputs (PPS and time-of-day) in both outdoor and indoor environments when GPS was absent or degraded by fusing 5G PRS, GPS, and the grandmaster clock. Oscilloquartz’s grandmaster uses a Zero Trust Architecture and accepts multiple timing sources to provide redundancy and resilient synchronization for national security, public safety, telecom, financial services, and other mission-critical infrastructure.
Adtran (NASDAQ:ADTN) announced that its Oscilloquartz platforms now support Galileo OSNMA, the first civilian GNSS authentication service, via firmware update for supported multi-band GNSS receivers. The upgrade verifies navigation messages using digital signatures and TESLA chain keys to ensure timing authenticity and protect against spoofing and manipulation. Available for OSA 5412, OSA 5422, OSA 5430 and OSA 5440, the feature pairs OSNMA with Oscilloquartz Syncjack™ probing to detect record-and-replay (meaconing) attacks by cross-checking GNSS against trusted PTP sources. The update requires no hardware replacement and aims to boost timing resilience for 5G, finance, data centers, energy and other critical infrastructure.
