Adtran announced that Vodafone Turkey has deployed its Oscilloquartz optical cesium atomic clock technology to bring new levels of resilient timing to its nationwide network. Adtran?s first-to-market solution will deliver robust protection against disruptions to GNSS signals, enabling Turkey?s leading service provider to maintain uninterrupted, reliable connectivity even while it readies 5G services. By combining its existing Adtran Oscilloquartz core grandmaster clock devices with the new optical cesium atomic clock technology, Vodafone Turkey has an ePRTC+?

solution that guarantees accurate network synchronization during any possible GNSS unavailability. Artitel also played a key role in the deployment, facilitating logistics and supply management. For enhanced redundancy, Vodafone Turkey is strategically deploying Adtran?s Oscilloquartz ePRTC+?

across five different sites. Central to the solution are the Oscilloquartz OSA 3350 ePRC+?, which utilizes optical pumping technology to achieve high-performance frequency stability, and Vodafone Turkey?s existing core grandmaster clocks, the OSA 5430 and OSA 5440. Along with the Oscilloquartz clock combiner, these components form the complete ePRTC+?

system. Capable of maintaining 100 nanoseconds holdover for at least 45 days, and typically up to 55 days, it surpasses current ITU-T G.811.1 standards. The solution provides Vodafone Turkey with optimal stability, outperforming the lifespan of other high-performance magnetic cesium clocks.

It also features a modular design, which includes a wide range of synchronization output interfaces and supports secured management capabilities, including SNMP ? essential for efficient network management and security.
