Oscilloquartz, a privately owned company headquartered in Switzerland, founded in 1949, operates as an ADVA Optical Networking company and employs approximately 80 individuals. Its main product focus is telecoms. The company offers solutions for time and frequency synchronisation, designing, manufacturing, and deploying end-to-end synchronisation systems over next-generation packet and legacy networks.
On July 30, 2026, Oscilloquartz secured a contract with a quantum computing firm to supply optical cesium solutions, specifically its OSA 3300 SHP and ESTU precision timing module, addressing the quantum computing sector's need for highly stable frequency references to maintain coherence and system synchronization. Previously, on July 29, 2026, Oscilloquartz integrated Galileo’s OSNMA authentication into its timing and synchronization platforms using u-blox GNSS technology, aiming to enhance the trust and resilience of GNSS-based synchronization for critical infrastructure. Earlier, on June 2, 2026, the company highlighted its expertise in bringing telecom-scale timing solutions to defense networks, underscoring timing's critical role in synchronizing systems and enabling data flows for modern missions. This followed news from June 1, 2026, concerning its ruggedSync™ Series OSA 5510, designed to deliver assured timing and extended holdover in MIL-qualified platforms for tactical deployable defense operations, especially in contested and GNSS-denied environments.
