VIAVI EdgeGM 7000 grandmaster clock

VIAVI Solutions has launched the EdgeGM 7000, a highly resilient Edge grandmaster clock building on the company’s SecurePNT portfolio. The product offers up to 25G Precision Time Protocol (PTP) and multi-orbit SecureTime^SM altGNSS^SM for comprehensive assurance of positioning, navigation and timing (PNT) services for critical infrastructure operations.

Essential networks throughout the world — 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 themselves can be attacked, with potentially catastrophic consequences. Governments around the world have begun mandating that critical infrastructure providers improve resilience of their networks through more responsible use of PNT services.

SecurePNT and SecureTime from VIAVI offer resilient timing, with multisource assurance combining signals from GNSS-dependent government and GNSS-independent commercial constellations across medium Earth orbit (MEO), geosynchronous Earth orbit (GEO) and low Earth orbit (LEO), respectively. The EdgeGM 7000 integrates 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 licence, and GNSS backup can be activated with an on-demand alternate GNSS GEO-L source licence over the air.

The clock exceeds Level 4 PNT resiliency as specified in the IEEE P1252 standard. It also incorporates PTP profiles for multiple industries, including telecommunications, enterprise, power and more.
