Selecting cesium atomic clocks
Our optical cesium atomic clock technology is transforming network synchronization. The OSA 3350 Super Enhanced Primary Reference Clock (OSA 3350 SePRC) and OSA 3350 Super Enhanced Primary Reference Clock+ (OSA 3350 SePRC+) far surpass the capabilities of legacy cesium. Our OSA 3350 SePRC provides 100 nanoseconds of holdover guaranteed for over 45 days, and our OSA 3350 SePRC+ delivers a record-breaking 100 nanoseconds of holdover for over 100 days. Both solutions ensure robust GPS/GNSS backup for PNT-critical infrastructure, including 5G, data centers and defense communications. Featuring our groundbreaking and unique optical pumping technology, the OSA 3350 SePRC and SePRC+ set new industry standards for enhancing the reliability and accuracy of PNT-dependent networks. This is the most significant advancement in cesium clock technology in over 30 years.
