OSA 5430 Series Compact PTP Grandmaster Clock
Compact, redundant, high-capacity PTP grandmaster, SB/MB-GNSS receiver
The OSA 5430 is a high-precision PTP grandmaster clock that delivers reliable, fully redundant timing across complex networks. Its modular and scalable design supports smooth migration from legacy systems while enabling next-generation technologies like LTE-A, 5G, and DOCSIS 3.1. For mission-critical applications, it can be upgraded with White Rabbit technology to achieve sub-nanosecond synchronization across multiple sites without new hardware.
Description
OSA 5430 Series PTP Grandmaster Clock
Advanced high-capacity synchronization solution
The OSA 5430 is a carrier-grade PTP grandmaster clock designed to provide precise and reliable timing across complex networks. It is particularly suited for organisations in utilities, finance, data centers, research institutions, and telecom operators that require high-accuracy synchronization for mission-critical operations.
The OSA 5430 is built for flexibility and scalability, making it ideal for smooth migration from legacy timing systems to next-generation IP networks. Its modular architecture allows operators to configure it according to specific network requirements, minimizing infrastructure changes while maximizing performance.
Key features and benefits:
- High-speed connectivity – Supports PTP, NTP, and SyncE over both 10Gbit/s and 1Gbit/s interfaces with hardware timestamping, enabling fast, accurate timing distribution.
- Fully redundant hardware – Protects all critical modules, ensuring high service availability and preventing performance loss during failures.
- Modular and configurable design – Can operate as ePRTC, PRTC A/B, SSU, PTP GM, boundary/slave clock, APTS, or NTP server, giving network designers maximum flexibility.
- Legacy system support – Handles Composite Clock, BITS, and T1/DS1/E1 interfaces, facilitating a seamless transition from older TDM networks to modern IP-based infrastructures.
- Syncjack™ technology – Built-in monitoring and assurance tools provide real-time visibility into synchronization accuracy, reducing the need for additional test equipment and manual checks.
- Operational simplicity – Ensemble Controller and Ensemble Sync Director, combined with GNSS assurance, simplify management and monitoring across multiple sites.
- Protected PTP-over-10Gbit/s interface – Delivers frequency, phase, and time synchronization over packet networks while supporting up to 1024 PTP slaves at 128pps, enabling large-scale deployments.
The OSA 5430 is upgradeable with White Rabbit technology, an optional license-based software feature that delivers sub-nanosecond synchronization for extremely timing-sensitive applications. This upgrade allows organisations to:
- Achieve ultra-precise timing across multiple sites, supporting demanding use cases in utilities, finance, research, and data centers.
- Enhance network reliability and compliance without replacing existing hardware.
- Future-proof infrastructure for next-generation technologies, including LTE-A, 5G, and DOCSIS 3.1 remote PHY deployments.
The OSA 5430 is ideal for organisations that need:
- A reliable, high-capacity synchronization solution for large-scale networks.
- To upgrade legacy systems while minimizing costs and operational disruption.
- High-accuracy timing to meet regulatory, compliance, and performance requirements.
- A flexible platform that can adapt to evolving network standards and future technologies.
By combining robust hardware, advanced monitoring, modular design, and the option for White Rabbit precision, the OSA 5430 delivers a complete solution for organisations seeking next-generation synchronization with maximum reliability and performance.
