Signal integrity tester Xena Z800 Freya

qualificationperformancecompatibility

Overview
The Xena Z800 Freya Ethernet traffic generator delivers protocol and physical-layer testing from 10GE up to 800GE using 112G/56G SerDes with PAM4 and 28G/10G SerDes with NRZ. It is intended for performance, functional and QA validation of switches, routers, NICs and optical modules, with focus on signal integrity and Bit Error Rate characterization.

Key Features

• Supports QSFP-DD800 and OSFP-800 physical modules
• Multi-rate testing: 10 / 25 / 40 / 50 / 100 / 200 / 400 / 800 GbE
• SerDes support: 112G/56G (PAM4) and 28G/10G (NRZ)
• Drives optical transceivers and direct-attach copper (DAC) cables
• Comprehensive Layer 1 (PCS/PMA) test functions
• Auto-Negotiation and Link Training (AN/LT) on all speeds; optional AN/LT Utility for selected module variants
• Available for modular 4U XenaBay B2400 chassis (2-slot per module) and fixed 1U XenaCompact chassis
• Complete software package: XenaManager, Xena OpenAutomation (XOA), standalone RFC2544 / RFC2889 / RFC3918 / Y.1564 suites

Layer 1 testing
The platform implements L1 capabilities including dynamic transceiver clock sweep, lane skewing, programmable PRBS modes and an integrated signal-integrity view for visual analysis of eye and lane behavior. Supports testing at 800GE, 400GE, 200GE, 100GE, 50GE with 112G/56G PAM4 and at 100GE/50GE/40GE/25GE/10GE with 28G/10G NRZ.

Auto-Negotiation & Link Training (AN/LT)
AN/LT is supported across all data rates. Optional AN/LT Utility (for Z800q Freya and Z800o Freya OSFP variants) exposes AN parameters and LT coefficients for detailed endpoint behavior analysis during negotiation and training procedures.

Software and automation
Management and test orchestration are provided by XenaManager (multi-user GUI) and XOA, a Python-based automation framework. Standalone applications enable standard RFC/Y.1564 test workflows and extendable scripting supports custom test methodologies and CI integration.

Form factor & integration
Z800 Freya modules fit into modular XenaBay B2400 chassis (each module requires two slots) or fixed XenaCompact 1U chassis, enabling compact 800G test deployments and lab integration with existing rack systems.
