- Compact Design with Maximum Efficiency
The OSA 5401 Series delivers highly accurate GNSS receiver and grandmaster clock functionality in an ultra-compact SFP form factor. Its advanced timing distribution architecture meets the synchronisation demands of modern radio access networks while minimizing space, power consumption, and deployment effort. The OSA 5401XG extends these capabilities to 10Gbit/s networks with multi-band GNSS support and additional constellations, including IRNSS, for improved timing accuracy and regional compliance.
- Extensive Synchronisation Capabilities
Despite its compact size, the OSA 5401 Series offers a broad range of synchronisation features, including Syncjack™, PTP, NTP, SyncE, spoofing detection, and extended holdover functionality.
- Accurate Timing Across Multiple Industries
Designed for telecommunications, utilities, finance, broadcasting, and other time-sensitive sectors, the OSA 5401 SyncPlug™ Series integrates easily with existing infrastructure to provide reliable and precise synchronisation.
- Compact Form Factor with Advanced Features
The optimised dual-frequency GNSS receiver delivers reliable performance even in challenging urban environments where small cells are commonly deployed. It provides accurate PTP phase and frequency synchronisation for base stations and small cell networks while supporting deeper synchronisation deployment across radio access networks. The OSA 5401XG further enhances functionality with multi-band GNSS, improved spoofing and jamming detection, extended holdover capabilities, PRTC-B compliance, and support for additional GNSS constellations, including IRNSS.
- Reliable Synchronisation in Challenging Conditions
The OSA 5401 Series is engineered to maintain accurate phase synchronisation even when GNSS signals are weak, obstructed, or compromised.
- Reduced Deployment and Operational Costs
Built for space and energy efficiency, the OSA 5401 Series helps lower installation and engineering expenses. The devices operate as GNSS receivers, Synchronous Ethernet sources, and grandmaster clocks while supporting both Layer 2 and Layer 3 PTP transport, along with simultaneous unicast and multicast operation. The OSA 5401XG also adds 10Gbit/s host compatibility, multi-regional navigation support, and the ability to handle up to 500,000 NTP transactions per second.
