ADTRAN HOLDINGS, INC. Adtran 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.
The OSA 3300 SHP and OSA 3350 SePRC+ redefine the capabilities of PRCs and ePRCs, unlocking new possibilities in their respective domains. The OSA 3300 SHP, with its superior Allan Deviation (ADEV) performance ? twice as accurate as the 3300 HP with the same 10-year lifespan ?
ensures exceptional stability and accuracy, making it an ideal choice for metrology institutes and scientific research facilities. Its advanced feature set enables these institutions to achieve new levels of precision in their timekeeping and calibration processes, directly driving advancements in scientific research and industrial applications. Meanwhile, the OSA 3350 SePRC+ is specifically designed to enhance holdover capabilities for PNT services.
This high-end optical cesium clock, together with our Super ePRTC+ combiner can maintain 100 days of 100-nanosecond precision, far exceeding previous industry records, and ensuring continuous and accurate timing even in environments where GPS/GNSS are unavailable.
