Highland Broadband has transformed internet connectivity in Halkirk, Scotland, previously the UK's slowest broadband location with speeds of just 2.8Mbit/s, using Adtran's XGS-PON fiber technology. The new network delivers Gigabit speeds up to 10Gbit/s to homes and businesses.

The deployment features Adtran's 631 ONTs and 8733 Wi-Fi 7 residential gateways for whole-home coverage, alongside AI-driven Mosaic One software for remote monitoring and optimization. This transformation demonstrates that rural fiber expansion is both achievable and commercially viable, providing a blueprint for bringing digital inclusion to underserved communities.

Adtran (ADTN) has partnered with 6WIND to deliver virtual broadband network gateway (vBNG) and virtual carrier-grade NAT (vCGNAT) solutions, integrating them into Adtran's Mosaic software suite. This collaboration enables service providers to replace expensive hardware-based BNGs with a scalable, software-driven alternative.

The solution runs as a virtual machine on commercial off-the-shelf servers, supporting key functions like RADIUS authentication, CGNAT, and dynamic routing. The partnership builds on previous collaboration that has already delivered over 12,000 6WIND routers as the Ensemble vRouter.

The integrated solution offers:

• Non-blocking BNG performance at multigigabit speeds
• Automated provisioning and subscriber monitoring
• Scalability from small networks to millions of subscribers
• Lower operational costs compared to traditional hardware

Adtran has secured two FTTH Innovation Awards at the FTTH Conference 2025 for its groundbreaking fiber technologies. The company's SDX 6405 optical line terminal (OLT) won in the 'Active infrastructure – central network' category, while its ALM fiber monitoring platform was recognized in the 'Installation equipment, tools, test & measurement instruments' category.

The SDX 6405 OLT supports simultaneous GPON, XGS-PON, and 50G PON on each port, enabling seamless network scaling and multigigabit services delivery over a single fiber. Its modular design allows providers to gradually expand 50G capabilities without disrupting existing infrastructure.

The ALM platform introduces deep PON assurance capability, providing real-time, in-service monitoring across the optical plant without requiring demarcation reflectors. This innovation helps operators detect and resolve issues proactively, improving service reliability while reducing operational costs.

Adtran has launched AccessWave50™, the industry's first full C-band tunable 50Gbit/s SFP56 DWDM PAM4 pluggable transceiver, designed for expanding 5G fronthaul capacity. The innovative solution replaces two 25Gbit/s transceivers with a single 50Gbit/s unit, featuring:

• Power consumption below 3W
• Zero-touch provisioning and auto-tuning capabilities
• 15km transmission range over SMF28 fiber
• Full C-band tunability
• Compliance with I-temp requirements for outdoor applications

The technology will be demonstrated live at OFC 2025, showcasing its ability to address growing bandwidth demands at the mobile network edge while optimizing fiber utilization and reducing operational costs for mobile network operators.

Adtran is set to showcase its FSP 3000 open line system (OLS) and coherent 100ZR+ QSFP28 transceiver at the Optical Internetworking Forum's (OIF) interoperability demonstration at OFC 2025. The demonstration, featuring 35 member companies, will highlight multi-vendor, multi-rate transport capabilities with coherent pluggable optics operating at 100Gbit/s, 400Gbit/s, and 800Gbit/s over an open, multi-span network.

The FSP 3000 OLS will transport these coherent signals across a 300km multi-span link, utilizing high-resolution flexgrid and colorless ROADMs with bidirectional inline amplifiers. The system features integrated optical monitoring and automated span equalization. Additionally, Adtran's coherent 100ZR+ QSFP28 pluggable transceiver, with 0dBm output power, will demonstrate low power consumption in a compact form factor.

Adtran (ADTN) has launched its new FSP 3000 IP OLS solution to address the growing demands of AI and data center traffic. The system combines amplification, filtering, and real-time monitoring in a compact 1RU design, offering automated operations and simplified management.

The solution features plug-and-play deployment and scalability from 400Gbit/s to 1.6Tbit/s per wavelength. Key features include:

• Zero-touch provisioning and automated span equalization
• Full-spectrum monitoring and OTDR-based fiber assurance
• Capacity for up to 8x 1.6Tbit/s in a single 1RU chassis
• Scalability up to 65 channels for larger infrastructure needs

The FSP 3000 IP OLS is offered as part of Adtran's optical-infrastructure-as-a-service, providing a turnkey approach that streamlines operations and reduces overhead.

Adtran has announced that Turin and Piedmont Internet Exchange (TOP-IX) has launched Italy's first time-as-a-service (TaaS) solution using Adtran Oscilloquartz technology. The service, developed in partnership with Italy's National Institute of Metrological Research, utilizes Oscilloquartz edge grandmaster devices across TOP-IX's fiber network.

The solution employs Adtran's OSA 5410XG and OSA 5412 grandmaster clocks, featuring multiple 10Gbit/s ports and Syncjack™ technology for real-time performance monitoring. This infrastructure provides precise timing and synchronization services to various sectors including finance, healthcare, and logistics, offering a cost-effective alternative to building private timing systems.

The service delivers a secure and reliable alternative to GNSS systems, with features including jamming and spoofing detection, multi-band GNSS receivers, and timing assurance capabilities. The implementation marks a significant advancement in Italy's digital infrastructure, enabling organizations to access precise timing services without investing in expensive dedicated systems.
