- Calnex Solutions plc designs, produces and markets test and measurement instrumentation and solutions for network synchronization, network emulation and telecommunications infrastructure validation in the telecoms, cloud computing and defence sectors; its core products include timing and synchronization solutions such as Paragon-neo (an 800Gb/s tester), Paragon-X, Sentinel and Sentry for network test, lab test and sync monitoring, as well as network emulation products such as Calnex SNE-X and NE-ONE for application performance testing, infrastructure testing, O-RAN conformance, data center efficiency, military network modeling, cyber ranges, XR and games testing. The company serves telecoms network operators, equipment providers, cloud hyperscalers, defence contractors and technology firms including BT, China Mobile, NTT, Ericsson, Nokia, Intel, Qualcomm, Nvidia and Meta; it operates globally with orders delivered to over 600 customer sites in 68 countries. Founded in 2006 and headquartered in Linlithgow, Scotland, Calnex maintains additional facilities in Belfast (Northern Ireland), Stevenage (England) and California (US), supported by sales teams in China and India and a worldwide partner distribution network.
Recent developments include the launch of Paragon-neo in late fiscal 2025 to target high-speed 5G, AI, quantum computing and defence applications, alongside expanded network emulation offerings following the acquisition of iTrinegy; the company terminated its distribution agreement with Spirent Communications effective July 2024 and strengthened sales channels by adding direct resources and partners in North America, Europe, India and Asia-Pacific. In November 2025, Calnex announced a partnership with Viavi Solutions for joint Open RAN testing solutions to enhance pre-validation and access Viavi's installed base; it also initiated development of a 1.6Tb/s synchronization solution for delivery in 2027 and reported FY2025 revenue growth of 12% to £18.39 million with a return to profitability. These initiatives reflect a strategic refocus on high-growth markets, cost optimization and product innovation amid telecoms recovery and diversification into cloud and defence.
