OSA 3350 ePRC+ Optical Cesium Atomic Clock

Optical cesium atomic clock with excellent frequency stability

The OSA 3350 ePRC+ cesium clock is the industry’s first ePRC optical cesium atomic clock solution, protecting synchronization networks from costly and dangerous interruptions to satellite signals. The Oscilloquartz’ OSA 3350 ePRC+ provides unprecedented stability and a significantly longer lifetime compared to all other ePRC cesium clocks. It’s also the first cesium clock on the market with built-in SNMP support. This innovation in the design of atomic clocks comes at a critical time when GNSS outages caused by jamming and spoofing attacks are on the rise. Long GNSS disruptions can cause severe network outages and so the OSA 3350 ePRC+ offers vital backup for mission-critical infrastructures that depend on satellite-based timing, such as mobile networks and power utilities. The OSA 3350 ePRC+ also meets the stringent performance demands as well as the cost points needed for mobile networks transitioning to 5G.

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.

OSA 3350 ePRC+

Optical cesium atomic clock with excellent frequency stability

The OSA 3350 from Oscilloquartz, an ADVA Optical Networking Company, is the first commercial optical cesium atomic clock specifically designed for ePRC application that require excellent holdover. It enables highly stable synchronization over an extended lifetime. It is more reliable, more accurate, and has a longer lifespan than legacy magnetic cesium clocks due to its advanced optical cesium technology. In addition to its outstanding frequency stability, the OSA 3350 also offers superior ePRTC performance to the G.811.1 specification, making it the perfect choice for deploying ePRTC solutions. The highest levels of availability can be ensured when satellite based synchronization solutions are complemented by ultra-stable atomic clocks. A market-leading G.8272.1-compliant ePRTC solution with improved holdover can be delivered with the OSA 3350 combined with a highly scalable grandmaster, such as the OSA 5430 or 5440 series.
