OSA 5430 Series (coreSync™ Core Grandmaster)

Fully Redundant Grandmaster Clock for High-Availability Network Synchronisation

The OSA 5430 Series is a high-performance synchronisation platform designed to meet the demanding phase, frequency, and time synchronisation requirements of modern communication networks. Built for LTE-A, 5G, cable, and packet-based infrastructure, it combines advanced synchronisation technologies with a fully redundant architecture to deliver exceptional reliability, scalability, and operational continuity.

  • Complete Hardware Redundancy
     The OSA 5430 is the first IEEE 1588 grandmaster clock platform to support PTP, NTP, and SyncE across multiple 10Gbit/s Ethernet interfaces while providing full hardware redundancy. If a critical module fails, a standby module immediately takes over, ensuring uninterrupted synchronisation performance and service delivery.

  • Customisable Without Downtime
     Its modular architecture allows components to be added, replaced, or upgraded without shutting down the system, enabling flexible customisation while maintaining continuous operation.

  • Proactive Synchronisation Assurance
     Built-in Syncjack™ assurance technology continuously monitors synchronisation performance and provides early alerts, helping operations teams identify and resolve issues before they affect network services.

  • Flexible and Scalable Design
     The OSA 5430 is designed to support the synchronisation demands of next-generation networks, including LTE-A, 5G, and cable infrastructure. Its scalable, modular design and fully redundant architecture ensure high service availability while eliminating single points of failure.

  • High-Capacity Synchronisation Platform
     Supporting both 10Gbit/s and 1Gbit/s interfaces with hardware timestamping, the OSA 5430 delivers precise timing for a wide range of modern applications and synchronisation environments.

  • Smooth Migration to Next-Generation Synchronisation
     The OSA 5430 combines the benefits of hardware redundancy, space efficiency, and scalability to support growing radio access networks. As the industry’s first protected PTP-over-10Gbit/s synchronisation solution, it delivers frequency, phase, and time synchronisation across packet-based networks. The platform supports up to 1024 PTP slaves at 128pps and offers multiple interface options to simplify migration from legacy synchronisation systems to next-generation network architecture.
