Advanced Site Synchronisation Solutions for Critical Network Infrastructure
The OSA 5405 Series is a versatile family of synchronisation solutions designed to deliver accurate and resilient timing for telecommunications, utilities, broadcasting, data centres, and other mission-critical applications. Available in multiple variants for indoor, outdoor, power utility, multi-band, and GNSS-challenged environments, the series provides reliable synchronisation through PTP and NTP while supporting the evolving requirements of modern network infrastructure.
The OSA 5405 Series delivers accurate onsite synchronisation directly from the smart antenna using PTP and NTP technologies. Designed for deployment in indoor, outdoor, and challenging environments, the series helps organisations transition from legacy timing systems while reducing dependence on traditional GNSS-based synchronisation. Available variants include the OSA 5405-I, OSA 5405-P, OSA 5405-O, OSA 5405-MB, and OSA 5405-S, each optimised for specific deployment requirements.
Engineered to meet the demanding synchronisation requirements of modern mobile networks, the OSA 5405 Series delivers the precise timing accuracy required for both 4.5G and 5G deployments.
The OSA 5405-I, OSA 5405-O, OSA 5405-MB, and OSA 5405-S help replace traditional GNSS antenna and coaxial cable installations with Ethernet-based connectivity, reducing deployment complexity, capital expenditure, and operating costs.
The OSA 5405 Series offers specialised variants for a wide range of applications and environments. Indoor and outdoor models support deployment in difficult locations, including urban areas where GNSS reception may be limited. The OSA 5405-MB enhances accuracy and resilience through multi-band GNSS technology, while the OSA 5405-I features an integrated GNSS receiver and antenna suitable for indoor window installations. The OSA 5405-S is designed for environments where GNSS signals are unavailable or impacted by poor reception, jamming, or spoofing.
By combining multi-constellation GNSS with LEO-based Satellite Time and Location (STL) technology, the OSA 5405-S delivers significantly stronger timing signals, providing improved synchronisation performance in challenging conditions.
The OSA 5405 Series combines advanced GNSS synchronisation with a comprehensive set of interfaces and management capabilities. The OSA 5405-P supports applications such as power utilities and automated substations with legacy timing interfaces including IRIG-B, NTP, and PPS, alongside satellite- and network-based synchronisation. Backup synchronisation through Synchronous Ethernet and PTP helps ensure high availability, while Ensemble Controller and Ensemble Sync Director with Syncjack™ and GNSS assurance features support efficient operation and management.
