OSA 3300-HP Optical Cesium Clock

Industry-first high-performance optical pumping cesium clock

The OSA 3300-HP from Oscilloquartz, an ADVA Company, is the industry’s first commercial optical cesium atomic clock for high-performance applications. Using the market-leading aPNT+™ platform, it provides highly precise synchronization for demanding applications such as metrology, timekeeping labs, and other applications with high accuracy requirements. As a result of its advanced optical cesium technology, its accuracy and clock stability are much higher, and its lifespan is much longer, as well as its robust design is much stronger than legacy magnetic cesium clocks. With its compact and portable design, the OSA 3300-HP is ideal for multiple applications, even in limited space environments.

In June 2023, ADVA Optical Networking SE has officially changed its name to Adtran Networks SE. The products of ADVA will continue to be available from CoverTel as usual. Logo change of products from ADVA to Adtran will be done progressively.
