Oscilloquartz

Oscilloquartz, founded in 1949 in Switzerland's watchmaking region, is a timing and synchronization company now a subsidiary of Adtran since 2021. The company designs products for utilities, defense, finance, IoT, broadcasting, and mobile networks including 5G. ADVA developed groundbreaking optical cesium atomic clocks including the OSA 3300-HP high-performance optical cesium atomic clock, OSA 3350 ePRC+ (industry's first ePRC optical cesium clock delivering 14-day holdover with 35 nanoseconds accumulated error), and OSA 3350 Super ePRC (SePRC) with extensive timing holdover and high-performance stability. These innovations address critical GNSS outages from jamming and spoofing attacks, offering vital backup for mission-critical infrastructures like mobile networks and power utilities. Oscilloquartz's coreSync technology leverages optical-pumping techniques using laser diodes. POST Luxembourg deployed ADVA's optical cesium atomic clock to combat GNSS attacks and improve PNT resilience. The solutions support quantum computing applications requiring ultra-precise timing synchronization.
