TestCenter 400G Appliances
Proven, scalable validation for high-performance 400G Ethernet networks
VIAVI TestCenter 400G Appliances provide comprehensive validation for data center, cloud, service provider, and enterprise networks transitioning to higher speeds. Built on the TestCenter A1, A2, A3 appliance families and dX and pX TestCenter test modules, these solutions enable engineering and operations teams to confidently design, deploy, and optimize 400G infrastructure while preparing for future migration to 800G and beyond.
400G Ethernet has become the foundation for modern data center fabrics, high-speed routing, and AI-ready infrastructures. While widely deployed, 400G networks still present significant challenges related to scale, interoperability, latency, and resiliency.
TestCenter 400G Appliances and Test Modules deliver a mature, field-proven platform for validating performance, conformance, and interoperability across Layer 2 through Layer 3. With support for multiple appliance form factors and port densities, TestCenter enables flexible testing strategies for labs, manufacturing, and live network environments.
