Teledyne LeCroy has unveiled the first integrated high-speed Ethernet traffic generation and protocol analysis solution for validating the limits of Auto-Negotiation and Link Training (AN/LT) for 800Gbps Ethernet.
An extension to the existing LinkExpert software, the new solution leverages the capabilities of both Xena Z800 Freya Ethernet Traffic Generator and SierraNet M1288 Protocol Analyzer to test the limits of Ethernet’s

This innovative and fully automated testing solution simplifies and accelerates interoperability testing across various Ethernet switches and network interface cards (NICs). It not only validates optimal test scenarios but also addresses challenging corner cases, helping to resolve complex issues related to optimizing high-speed Ethernet connectivity before deployment in data centers. These tests include:
- Testing each Equalizer Tap to its maximum limit to verify protocol compliance and ensure links re-establish if limits are exceeded.
- Verifying the robustness and stability of the SerDes interface by repeatedly configuring and measuring performance variations.
- Validating that all speeds can be negotiated to support backwards compatibility.
- Ensuring links can be established starting from any preset.
The SierraNet M1288 provides full stack capture, deep packet inspection and analysis for links up to 800 Gbps. Additionally, the SierraNet M1288 offers jamming capabilities for direct error injection on the link at wire speed to fully validate negative test scenarios.
The Xena Z800 Freya Ethernet traffic generator is a versatile solution for performance and functional testing of Ethernet network infrastructure and equipment including switches, routers and NICs. The Z800 Freya can test up to 800GE using PAM4 112G SerDes and is designed to achieve the best possible signal integrity and Bit Error Rate performance. Signals can be analyzed in advanced signal integrity view, which provides visual information on the quality of the signal.
