Z800qx Freya

2 QSFP-DD800 ports for testing 8 speeds up to 800Gbps

Download Datasheet

The Z800qx Freya is a 2-port traffic generator that can test eight Ethernet speeds – 800GE, 400GE, 200GE, 100GE, 50GE, 40GE, 25GE and 10GE – using 112G/56G/25G/10G SerDes.

This is a versatile solution for testing the performance and functionality of Ethernet network infrastructure and equipment including switches, routers and NICs.

Equipped with 2 QSFP-DD800 cages the Z800qx Freya can test speeds ranging from 10GE NRZ to 800GE using 112G PAM4 SerDes for exceptional flexibility.

The module also provides advanced tools for helping developers optimize signal integrity and Bit Error Rate (BER) performance on the tested links.

Z800qx Freya supports extensive L1 test features, with the integrated Xena PHY providing valuable insights into advanced PCS and PMA layer testing including dynamic transceiver clock, sweep, lane skewing and PRBS modes. Signals can be analyzed in advanced Signal Integrity View (SIV), to provide visual information on signal quality.

Purchasing the Advanced Layer 1 Solution Track provides access to additional Layer 1 test features for Z800qx.

Up to 6 x Z800qx Freya can be installed in the Xena B2400 chassis i.e. 12 x 800G ports in a single chassis, or it can be delivered in the Compact chassis, making it the smallest and lightest 800G Ethernet test solution on the market.

Z800qx Freya comes complete with XenaManager, the intuitive multi-user management software for generating and analyzing traffic. Also included is Xena OpenAutomation (XOA), an open-source scripting and automation framework designed to help test engineers make the most of Xena testers with tailored tests and standardized test methodologies.

Ethernet Auto-Negotiation & Link Training Test Tools

Z800qx Freya traffic generators support Auto-Negotiation and Link Training (AN/LT) on 112G SerDes and 56G SerDes (PAM4).

Purchasing the Advanced AN/LT Solution Track provides additional advanced AN/LT features for Z800qx including AN/LT Link Trace visibility for thorough testing of the endpoint behavior during AN and LT process.

The Advanced AN/LT Solution Track adds insight, visibility, and configuration options to the AN and LT process making it easy to analyze DUT behavior during AN/LT, configure and optimize relevant AN parameters and LT coefficients, on PAM4 signals.

Connector insertions

Xena uses high-quality 112Gbps-capable electrical connectors on Z800 Freya modules for optimal signal integrity and performance. However, all connectors experience wear when inserted, resulting in decreased signal integrity over time. The specification below is the minimum number of insertions where optimal signal integrity is guaranteed:

Connectors, minimum number of guaranteed insertions: 1000 cycles
