Since magnetic cesium clocks were born more than 50 years ago, the technology has not seen a major improvement. Until now. With our OSA 3350 ePRC+ optical cesium atomic clock, we’ve productized the most innovative technology for making more efficient use of cesium atoms. At a critical time when GNSS outages caused by jamming and spoofing attacks are increasing in frequency and duration, we’re taking holdover capabilities and long lifetime to the next level. Our OSA 3350 ePRC+ provides vital protection for mission-critical networks such as radio access, government infrastructure or communication networks infrastructure, and meets the strict performance demands and cost points needed for 5G mobile networks.
