      Adtran today launched two new optical cesium atomic clocks that set new standards in network time synchronization: the OSA 3300 Super High-Performance (OSA 3300 SHP) and the OSA 3350 Super Enhanced Primary Reference Clock+ (OSA 3350 SePRC+). As part of Adtran's Oscilloquartz portfolio of industry-first optical cesium clocks, the devices leverage unique, state-of-the-art optical pumping technology to meet evolving demands across applications from scientific research to critical PNT infrastructure. The OSA 3300 SHP offers exceptional stability and accuracy, making it a valuable tool for metrology institutes and scientific research facilities. In contrast, the OSA 3350 SePRC+ is specifically designed to enhance holdover capabilities for PNT services. It maintains 100 days of 100-nanosecond precision, providing continuous and accurate timing even in environments where GPS/GNSS is unavailable. This makes it a crucial component for ensuring the integrity of mission-critical networks and supporting vital infrastructure and defense operations with reliable backup timing.
