Safran - StarSync™ U4
The StarSync™ U4 is the next-generation high-performance time server and interoperability platform designed to deliver resilient and precise timing across high-speed Ethernet networks. Combining White Rabbit, PTP and NTP in a compact modular platform, it provides a common timing infrastructure for critical applications requiring deterministic time and frequency distribution.
Featuring four high-speed 1G/10G SFP+ interfaces, advanced processing capabilities and a carrier-grade timing architecture, the StarSyncTM U4 enables flexible deployment as a Grandmaster, Boundary Clock or interoperability node. Multi-source redundancy, seamless failover, advanced holdover capabilities and integrated monitoring ensure continuous synchronization even in demanding network environments.
Designed for modern mission-critical infrastructures, the StarSync™ U4 combines comprehensive management, advanced cybersecurity and optional expansion modules to address evolving synchronization requirements. From financial trading, telecom and datacenters to defense, utilities and scientific facilities, it provides a scalable, future-ready platform for accurate, secure and reliable timing distribution.
