The Oscilloquartz coreSync OSA 3300-HP high-performance optical cesium atomic clock, says the company, ushers in a new age of precise synchronization with unprecedented stability. The OSA 3300-HP has a 10-year lifetime compared to the five years offered by currently available high-performance magnetic clocks.

Offered as the market’s only high-performance optical cesium clock, the OSA 3300-HP, provides the resilience required for PNT assurance in critical infrastructure and empowering service providers to deliver differentiated SLA timing offerings with integrated GNSS backup. The feature-rich device has embedded Ethernet- and IP-based management as well as a user-friendly touchscreen GUI.

“The launch of our coreSync OSA 3300-HP marks a key milestone in the design of atomic frequency and phase standards,” says 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 the ultimate synchronization backup for networks that rely on GNSS-based timing, combining high accuracy with outstanding availability. Offering performance that far exceeds best-in-class magnetic cesium devices, the OSA 3300-HP 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 radically more efficient compared to existing primary reference clock (PRC) technologies, says the company.

Its product lifespan is 100% longer than competing high-performance magnetic cesium clocks; the OSA 3300-HP delivers optimum stability for over 10 years. What’s more, says the company, further to the launch of the OSA 3300-HP, it is also announcing a dual-purpose enhancement of its OSA 3350 ePRC+. Now, as well as providing phase holdover as part of ePRTC systems, it can be utilized as a free-running frequency source with enhanced standard performance.

Patrick Berthoud, time and frequency chief scientist at Oscilloquartz, ADVA adds, “As well as meeting new sync requirements, our OSA 3300-HP will help simplify operations with its easy-to-use GUI for intuitive configuration and operation. These devices will support advances in a host of different technology fields. Able to meet the most demanding applications in data centers, financial networks, smart grids, transportation, metrology, scientific research and more, they will also be a foundation for future innovation as we continue to expand the boundaries of possibility for accuracy and stability.”
