Adtran has introduced the OSA 5401XG SyncPlug™, a compact SFP-based grandmaster clock designed to deliver PTP and NTP synchronization in 10Gbit/s edge and access networks. The new Oscilloquartz device eliminates the need for dedicated rack space or external appliances by integrating full synchronization capabilities directly into standard 1Gbit/s or 10Gbit/s ports. Consuming less than 2.5W, it provides a space- and power-efficient solution for telecom, energy, defense, and enterprise deployments.
The OSA 5401XG SyncPlug™ supports PTP grandmaster, boundary, and slave clock modes, Stratum 1 NTP server functionality, and SyncE for frequency synchronization. With multi-band GNSS (L1 and L5) and compliance with PRTC-B standards, the device enhances accuracy while supporting regional navigation systems such as India’s IRNSS. It also offers advanced spoofing and jamming detection, extended holdover, and up to 500,000 NTP transactions per second, ensuring resilience and scalability for modern timing-critical applications.
Adtran positions the OSA 5401XG SyncPlug™ as a way to extend high-precision synchronization deeper into constrained environments. By combining timing distribution, resilience, and advanced GNSS support in a plug-and-play form factor, the solution targets use cases from mobile backhaul and energy grids to government and enterprise networks.
- SFP-based grandmaster clock for 10Gbit/s edge and access networks
- Supports PTP (grandmaster, boundary, slave), NTP Stratum 1, and SyncE
- Consumes <2.5W; requires no rack space or external cabling
- Multi-band GNSS with spoofing/jamming resilience; PRTC-B compliant
- Handles up to 500,000 NTP transactions per second
“As networks evolve, precise timing has to reach further, faster and into more constrained environments. That’s exactly what the 5401XG SyncPlug™ is built for,” said Gil Biran, GM of Oscilloquartz, Adtran.
🌐 Analysis: Synchronization has become a critical enabler for 5G backhaul, smart grid, defense, and enterprise systems. Adtran’s move to embed full grandmaster functionality into an SFP module lowers deployment barriers for operators who need to extend precision timing without additional rack space or power overhead. Competitors such as Microchip, Meinberg, and Calnex have also expanded compact timing portfolios, but Adtran’s integration at the SFP level underscores a shift toward highly distributed, easily deployable synchronization solutions.
