Oscilloquartz, an ADVA company, recenly launched its enhanced primary reference time clock (ePRTC) system to enable unprecedented timing accuracy and stability even when the GNSS signal is lost.
The technology provides the ideal timing source for mission-critical transport systems, such as utility networks, government infrastructure and radio access networks, and provides the strict synchronization needed for LTE-A and 5G applications.
Featuring the OSA 3230B ePRC atomic cesium clock connected to an Oscilloquartz clock combiner and grandmaster, the new solution offers the extremely stable frequency of a cesium clock with the UTC-traceable signal provided by GNSS. When combined with the OSA 5430, the OSA ePRTC system is the only solution available that provides full hardware redundancy and multiple fan-out options including PTP over 10Gbit/s, claims the Company.
The dangers of reliance on GNSS alone have become a serious concern across a wide range of industries. Without backup, loss of signal would have a profound impact on critical infrastructure, financial institutions, and military capabilities. PTP packet-based mobile networks are also highly susceptible to outages unless they are able to hold time and maintain accuracy when GNSS is unavailable.
The OSA ePRTC system removes this vulnerability while delivering higher performance levels than standard PRTC systems and giving operators control of their network synchronization. The solution comprises two OSA devices: an OSA 3230B ePRC cesium clock compliant to G.811.1 ePRC, which is connected to either an OSA 5421 or OSA 5430 clock combiner and grandmaster clock compliant to G.8272.1 ePRTC. This provides phenomenal holdover accurate to UTC within +/-100nsec for up to two weeks, ensuring resilience and optimized performance.
