First Edge grandmaster clock with 25G PTP and multi-orbit altGNSS resiliency

VIAVI Solutions Inc. has launched EdgeGM 7000, a highly resilient Edge Grandmaster Clock building on the industry-leading SecurePNT portfolio. EdgeGM 7000 offers up to 25G PTP and multi-orbit SecureTimeSM altGNSSSM for the most comprehensive assurance of Positioning, Navigation and Timing (PNT) services employed in critical infrastructure operations worldwide.

Essential networks worldwide – including 5G/6G telecommunications, AI hyperscale data centres, defence, public safety, transportation, aviation, energy and finance – rely on publicly available GPS and GNSS signals for efficient data synchronisation based on timing and location. These vulnerable and single-source signals are occasionally unavailable or at risk of being jammed or spoofed, or satellites can be attacked, with potentially catastrophic consequences. Governments worldwide have begun mandating that critical infrastructure providers improve the resilience of their networks through more responsible use of PNT services.

SecurePNT and SecureTime from the company provide the most resilient timing in the industry, with multisource assurance combining signals from GNSS-dependent government and GNSS-independent commercial constellations across MEO, GEO and LEO, respectively. The EdgeGM 7000 combines advanced and scalable resiliency and PTP speed capabilities in a compact half 19” wide and 1U height rack-mountable unit with scalable software options. For instance, it can be upgraded from 1/10G to 25G PTP with a simple license, and GNSS backup can be activated with an on-demand alternate GNSS GEO-L source license over the air. EdgeGM exceeds Level 4 PNT resiliency as specified in the IEEE P1252 standard. It also includes PTP profiles for multiple industries, such as telecommunications, enterprise, power, etc.

“The world has seen a steady rise in threats to critical infrastructure, including disruption to the Positioning, Navigation and Timing services that are so vital to secure operations,” said Doug Russell, senior vice president, AvComm, VIAVI. “With the EdgeGM 7000, VIAVI is enhancing our portfolio to stay ahead of a rapidly evolving threat landscape, providing customers with the industry’s most powerful features in a flexible and scalable architecture.”
