800G Ethernet Testing
Our offering for 800G Ethernet Testing, a former Spirent business, delivers the industry’s first 800G test and validation solutions.
Validating 800G with Realistic Traffic and Stress Testing
800G Ethernet networks must be tested against real-world traffic conditions to ensure performance at scale. VIAVI emulates complex traffic patterns, protocol behaviors, and stress scenarios to help vendors and operators uncover hidden issues early. Learn how to enable accurate, repeatable 800G validation for next-gen data center and cloud infrastructure.


Strategic 800G Ethernet Testing to Avoid Costly Deployment Risks
Jumping into 800G deployments without a clear test strategy can lead to performance issues, integration delays, and missed timelines. VIAVI helps customers validate critical components early in the development cycle, enabling smooth integration and reliable scale-out. Learn how proactive 800G testing supports successful transitions from lab environments to operational readiness.
Addressing 800G Ethernet Design Challenges with Scalable Test Solutions
Deploying 800G networks introduces complex design and validation challenges—from PAM4 signal integrity and forward error correction (FEC) to interoperability. Our solutions help validate performance, reliability and performance across evolving Ethernet architectures. Learn how to overcome key hurdles with proven 800G testing strategies.
