ADVA on Thursday launched what it claims 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 significantly longer lifetime compared to all other ePRC cesium clocks, said the Company. 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.
Featuring an all-digital design, the OSA 3350 ePRC+ leverages optical-pumping techniques. It greatly improves performance by providing an extremely stable frequency source. When used with enhanced primary reference time clocks (ePRTCs), the OSA 3350 ePRC+ delivers holdover for 14 days with an accumulated error of up to 35 nanoseconds. This far exceeds the ITU-T ePRC G.811.1 standard that requires an accumulated error under 70 nanoseconds . The OSA 3350 ePRC+ also delivers optimum stability for over 10 years, which is 100% longer than the lifespan of high-performance magnetic cesium clocks, claims ADVA.

The incredible stability and accuracy that our OSA 3350 ePRC+ generates will bring essential improvements needed for 5G and other critical infrastructures deriving timing from GNSS.
