04 June 2020 -- ADVA (FSE: ADV) today launched 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 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.
