TestCenter D2 1.6T Appliance

Accelerating Validation for AI-Scale Networks and Hyperscale Fabrics

Engineered to address the unique challenges of AI networking, this comprehensive 1.6T solution spans Layer 1 through Layer 3 and beyond, identifying interconnect bottlenecks, latency hotspots, and fault-tolerance gaps that limit GPU utilization and hinder AI cluster scalability.

Hyperscale Validation with Real-World Emulation

VIAVI TestCenter is the unified validation platform powering the D2 1.6T Appliance, purpose-built to validate AI data centers, neoclouds, service provider infrastructures, and high-capacity network devices. Designed for the next generation of Ethernet speeds, TestCenter delivers deterministic, repeatable, and scalable validation for multi-terabit environments.

TestCenter D2 1.6T Appliance generates complex, realistic traffic patterns to emulate demanding AI workloads, including RoCEv2 and CCL flows with congestion control. It supports sustained full-load operation, long-duration traffic runs, and protocol stress testing, enabling comprehensive validation of high-capacity switches, routers, fabrics, and congestion-control mechanisms.

As a complementary solution to the VIAVI ONE LabPro ONE-1600 Test Module, the TestCenter D2 extends validation coverage with high-density, multi-rate Ethernet testing, deep Layer 2–3 protocol analytics, and full automation at hyperscale. Together, TestCenter and ONE LabPro provide a complete ecosystem for validating next-generation interconnects, optics, and network devices at 800G and 1.6T.

With rapid adoption of these higher Ethernet speeds driven by AI, VR/AR, and edge computing, the TestCenter 1.6T solution ensures the reliability, performance, and interoperability required for next-generation networks. Accelerate time-to-market, gain actionable insights, and validate the resilience of high-speed AI infrastructures with confidence.
