Z800 Freya

for testing 56/112G SerDes Ethernet

Z800 Freya 56G or 112G SerDes Ethernet TGA test solution

Z800 Freya is the newest addition to our range of high-speed Ethernet traffic generators. Named after the Nordic god of fertility, Z800 Freya supports testing of 50G PAM4 / 100G PAM4 / 200G PAM4 / 400G PAM4 / 800G PAM4 using 112Gbps SerDes or 56Gbps SerDes based Ethernet.

Speeds and technology

Z800 Freya uses the latest version of Pulse Amplitude Modulation (PAM4), which doubles the SerDes speed to 112Gbps and the Baud rate to 56GBaud or 56Gbps SerDes and the Baud rate to 28GBaud

Z800 Freya is designed for 800G switch, transceiver and PHY design validation & Quality Assurance. Key features incl.:

  • QSFP-DD800 and OSFP-800 supported
  • Drives optical transceivers and DACs
  • Auto-Negotiation and Link Training (AN/LT)
  • Extensive L1 features
  • Test automation via CLI/XOA

Hardware

There are 4 versions of Z800 Freya (see table below). Each version can be used in Xena’s modular 4U XenaBay chassis. Z800 Freya 4S modules are also available in Xena’s fixed 1U chassis: the XenaCompact.

The Z800 Freya test modules are also used for Xena’s award-winning ANLT test solution – the FreyaCompact ANLT Test Appliance.

Software

All Xena solutions includes user-friendly software to make it quick and easy to perform a multitude of relevant performance, QA, compliancy and functional testing: XenaManager, applications for automated RFC 2544, Y.1564, RFC 2889 and RFC 3918 testing, Xena OpenAutomation and XenaTimeSynch.

The Xena platform also includes Z10 Odin test modules for testing 10Mbps to 10G using NRZ, Z100 Loki test modules for testing 10G to 100G using NRZ, and Z400 Thor for testing 10 to 100G using NRZ and 100G to 400G using PAM4.

Link Training Process and Optimization

This technical note explains in detail how Z800 Freya tests the link training process to help you optimize the performance of 112G SerDes devices.

It covers: presets, coefficient values and step sizes, link training, Xena’s LT algorithm, how to test the performance of a DUT’s LT, algorithm, FIR filter, the relation between emphasis and tap coefficients, & coefficient settings in Z800 Freya.
