Netnod and Adtran Fortify Sweden’s National Timing Infrastructure with Optical Cesium Clocks

In a move to fortify Sweden’s national infrastructure against emerging digital threats, Netnod is implementing Adtran’s coreSync OSA 3300-HP, an optical pumping cesium atomic clock technology. This strategic upgrade aims to enhance the precision and reliability of timing services vital to the nation’s economy, spanning sectors from finance to next-generation telecommunications like 5G.

Sweden’s leading position in digital services and telecommunications underscores the critical need for robust timing services, which are fundamental to the functioning and security of digital infrastructures. The introduction of coreSync OSA 3300-HP by Netnod, a company specializing in providing internet exchange, DNS, and time services in the Nordics, aims to provide enhancements in the accuracy, stability, and durability of timing synchronization services across the country.

By deploying Oscilloquartz super ePRC technology across six pivotal timing centers nationwide, Netnod addresses the growing concern over GNSS vulnerabilities. The optically pumped cesium technology of the coreSync OSA 3300-HP offers a highly stable and precise alternative timing source, providing frequency stability and an operational lifespan double that of traditional magnetic cesium clocks.

This collaboration is a step towards securing Sweden’s digital infrastructure against GNSS threats and sustaining the country as a frontrunner in digital innovation and infrastructure resilience. Stuart Broome, GM of EMEA sales at Adtran, notes the critical role of Netnod in the Nordic ICT and multimedia sector, highlighting how leveraging the coreSync OSA 3300-HP fortifies Sweden’s critical national infrastructure, facilitating uninterrupted operations and expansion for a wide array of digital services and networks.
