ADVA has introduced its Oscilloquartz high-performance optical cesium atomic clock. The coreSync OSA 3300-HP is ADVA’s latest innovation in assured positioning, navigation and timing (PNT).

Following ADVA’s launch of an optical pumping timing solution two years ago, the OSA 3350 ePRC+, the OSA 3300-HP takes the technology to new levels. It has a 10-year lifetime compared to the five years offered by currently available high-performance magnetic clocks.

As a high-performance optical cesium clock, the OSA 3300-HP sets a new benchmark for precision and availability, ADVA claimed, providing the resilience required for PNT assurance in critical infrastructure and empowering service providers to deliver differentiated service-level-agreement timing offerings with integrated GNSS backup.

The feature-rich device has embedded Ethernet- and IP-based management as well as a user-friendly touchscreen graphical user interface.

“The launch of our coreSync OSA 3300-HP marks a key milestone in the design of atomic frequency and phase standards,” said Gil Biran, GM of Oscilloquartz, ADVA. “After many years of extensive work in our Swiss laboratories supported by the European Space Agency, we now have a mature, state-of-the-art technology that enables a major leap in the accuracy and stability of network timing while providing a substantially longer lifetime.”

Atomic clocks offer synchronization backup for networks that rely on GNSS-based timing, combining high accuracy with outstanding availability. The OSA 3300-HP commercial high-performance optical cesium atomic clock features an all-digital design and leverages optical-pumping techniques using laser diodes. This enables it to measure 100 times the number of atoms, making it more efficient compared to existing primary reference clock (PRC) technologies.
