A new approach
Xena’s new Freya test modules use a proprietary architecture for testing all Layer 1 functions at 100, 200, 400 and 800 Gbps Ethernet using 112 Gbps SerDes. Called “Xena PHY”, the new approach gives test engineers unparalleled flexibility to rapidly test new features and standards, and provide superior signal integrity when used with electrical cables.
The functional blocks of a typical Ethernet PHY
This White Paper outlines the functional blocks of a typical Ethernet PHY using a 112 Gbps SerDes to illustrate the complexity at Layer 1 of the latest Ethernet standard. It also outlines critical test scenarios that can be implemented only through direct access to all Layer 1 functions thanks to Xena PHY.
