Freya

What is Freya?

Freya is the latest addition to Valkyrie product line, Xena’s stateless Ethernet Traffic Generation and Analysis (TGA) solution.

Named after the Nordic god of fertility, Freya supports testing of 112Gbps SerDes PAM4 based Ethernet at data rates of 100G / 200G / 400G / 800G.

Speeds and technology

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

Freya is designed for 800G switch, transceiver and PHY design validation & Quality Assurance.

Other features:

• 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/Python Lib

Hardware

There are 4 versions of Freya (see table below). Each version can be used in Xena’s modular 4U ValkyrieBay chassis. Freya will subsequently be made available in Xena’s fixed 1U chassis: the ValkyrieCompact.

Software

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

The Valkyrie platform also includes Odin test modules for testing 10Mbps to 5G using NRZ, Loki test modules for testing 10G to 100G using NRZ, and Thor for testing 10 to 100G using NRZ and testing 100G to 400G using PAM4.
