VIAVI & Calnex Testbeds for End-to-End Conformance & Performance

Pre-Certify Open RAN with Confidence

Calnex/Viavi
Plug-and-play testbeds ready today for O-RU, O-DU & O-CU vendors — cover protocol, signal & timing across the full ecosystem.

The shift toward open, multi-vendor radio access networks (Open RAN) is reshaping 5G and paving the way for 6G. But innovation only counts when equipment meets rigorous standards. Multivendor ecosystems must deliver on performance, security, interoperability, and reliability at scale. 

By collaborating, VIAVI and Calnex bring together two proven test-platforms to simplify pre-certification testing, ultimately helping you avoid costly delays or failures at official labs.   

These testbeds combine VIAVI’s platforms, such as TM500, XEdge, TeraVM, with Calnex’s hardware for synchronization and impairment emulation (Paragon-neo, SNE-Ignite, SNE-X).  
 

What We Offer  

Our fully integrated test-solutions deliver immediate access to three turnkey testbeds:


End-to-end and cybersecurity
test solution for fronthaul & midhaul.


O-RU & O-DU test
solution with S-plane testing capability.


Core-network emulation
test bundles for backhaul scenarios.

 
 

Who Should Use This  

  • Network-equipment manufacturers developing O-RU, O-DU, or O-CU products.
  • Test labs building out Open RAN pre-certification capability.
  • Service-providers and integrators validating multi-vendor ecosystems prior to deployment.
  • Research/start-up spin-outs entering the Open RAN market and needing a proven test platform.  

Key Benefits

  • Faster time-to-test: Deploy plug-and-play testbeds with minimal debug overhead.
  • Full suite coverage: Test O-RAN and 3GPP conformance (WG4, WG5, TIFG) plus realistic impairments such as jitter, delay, multi-cell handovers.
  • Avoid failure risk: Pre-validate in-house so you’re ready for official lab certification with confidence.
  • Cost-efficient: Reduce the need for custom lab build-outs and long integration timelines.

Why Us  

VIAVI brings decades of network-test, monitoring and assurance expertise; Calnex brings deep emulation and synchronization hardware used across telecom infrastructures. Their combined offering streamlines the lab-build and interoperability challenge that many Open RAN developers face today.  Ready to accelerate your Open RAN development? Contact us today to explore the test-platform bundles and schedule a demo. Don’t wait until the final certification lab — validate now, deploy with confidence.

Solutions

During the development phase, many O-RUs are only tested with a single O-DU/O-CU vendor, which results in failure under real-world network conditions. This issue is compounded as the industry lacks tools to emulate realistic fronthaul conditions. Our partnership with Calnex puts these tools directly into the developers’ hands to vastly speed and simplify Open RAN test lab setup.

Companies urgently need in-house labs to validate their Open RAN systems, but establishing them has traditionally required equipment from multiple vendors and can take several months of debugging to ensure interoperability. VIAVI and Calnex's offerings are highly complementary, and we’ve undertaken the complex integration work to create these first-of-their-kind comprehensive testing systems and eliminate the issues that have plagued many developers.
