Optical pumping cesium clocks

OSA 3350 / 3300 / 3250 / 3200 · ePRC / ePRTC

Adtran Oscilloquartz optical cesium atomic clocks leverage optical pumping to set new precision and performance benchmarks for network operators, metrology institutes, scientific institutions and national timekeeping authorities. Accuracy and up to ten times greater clock stability exceed ITU-T G.811.1 ePRC; combined with core grandmasters as an ePRTC, the most capable optical cesium solutions provide 100 nanoseconds of holdover for up to 100 days, with twice the lifespan of legacy magnetic cesium.

edgeSync+ mid-size PTP grandmasters

OSA 5422 · IEEE-1588 / NTP / SyncE · 10G

edgeSync+™ mid-size PTP grandmasters combine high-performance synchronization, advanced timing resilience and flexible network integration in scalable edge platforms. With support for IEEE-1588 PTP, NTP, SyncE, high-speed 10Gbit/s connectivity and advanced GNSS technologies, they enable operators to meet stringent synchronization requirements across both modern packet-based and legacy infrastructure — including White Rabbit PTP, High-Accuracy Time Transfer and ePRTC capabilities.
