Calnex and VIAVI Expand Partnership for Network and Application Performance Validation

EDINBURGH, Scotland, Oct. 7, 2026 /CourierPR/ -- Calnex Solutions Plc and VIAVI Solutions have expanded their strategic partnership to deliver end-to-end network and application performance validation for next-generation networks. This collaboration aims to enable customers to recreate real-world network conditions, validate user experience, and accelerate deployment in key markets such as AI, Data Center, Defense, Satcom, and Enterprise.

The combined portfolio of Calnex and VIAVI will offer realistic traffic generation, user emulation, and network impairment technologies. This integrated solution will allow network infrastructure professionals to test and validate applications and services before deployment, ensuring that they perform as expected in production environments. The expanded partnership builds on the companies' existing collaboration for the comprehensive testing of Open RAN products across the protocol, signal, and timing domains, leveraging VIAVI's TM500, TeraVM, and XEdge platforms and Calnex's Paragon-neo, SNE-Ignite, and SNE-X.

Graeme Urquhart, Vice President of Sales at Calnex Solutions, expressed excitement about the expanded partnership.

Mark Bateman, Vice President of Sales and Channel for Lab and Production at VIAVI, echoed Urquhart's sentiments.
