Teledyne LeCroy has announced an integrated platform for validating the limits of auto-negotiation and link training (AN/LT) in 800-Gbps Ethernet. As an extension to the existing LinkExpert software, the new functionality leverages the Xena Z800 Freya Ethernet traffic generator and the SierraNet M1288 protocol analyzer to test Ethernet’s AN/LT specifications.

The fully automated test platform simplifies interoperability testing across various Ethernet switches and network interface cards. It tests each equalizer tap to its maximum limit to verify protocol compliance and ensure links re-establish if limits are exceeded. The system also verifies the stability of the SerDes interface and validates that all speeds can be negotiated to support backward compatibility.
The SierraNet M1288 protocol analyzer provides full stack capture, deep packet inspection, and analysis for links up to 800 Gbps. It also offers jamming capabilities for direct error injection on the link at wire speed. The Xena Z800 Freya Ethernet traffic generator can test up to 800G Ethernet using PAM4 112G SerDes, achieving the best possible signal integrity and bit error rate performance.
LinkExpert with the AN/LT test functionality is now shipping as part of the SierraNet Net Protocol Suite software.
