ADVA launches industry's first ePRC optical cesium clock solution

ADVA (FSE: ADV) has launched the industry´s first ePRC optical cesium atomic clock solution, protecting synchronization networks from costly and dangerous interruptions to satellite signals, the company said.

The Oscilloquartz OSA 3350 ePRC+ provides unprecedented stability and significantly longer lifetime compared to all other ePRC cesium clocks. 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. With a fully modular design, the optical cesium solution features a wide range of telecom synchronization output interfaces and supports modern and secured management capabilities with SNMP.
