Z100qx Loki 4-port 100G Ethernet traffic generator

 

The Z100qx Loki is a 4 port Ethernet traffic generator capable of testing five NRZ speeds: 100GE, 50GE, 40GE, 25GE and 10GE.

This flexibility is provided via 4 physical transceiver cages, supporting QSFP28 transceivers.

The Z100qx Loki is available in a single-slot 1U Compact chassis, or in the modular B2400 chassis.

Users can configure up to 36 Loki 100G ports in a single B2400 chassis (i.e. 9 x Z100qx), or combine it with Odin, Loki, Thor and Freya traffic generators in the same chassis for unmatched convenience and flexibility.

The result is a versatile solution for performance and functional testing of network infrastructure and Ethernet equipment such as chips, switches, routers, NICs, taps, transceivers, cables, packet-brokers, and backhaul platforms.

Included with the Z100qx Loki is XenaManager3 (XM3), the intuitive multi-user management software for generating and analyzing traffic. XenaManager makes it easy to configure and conduct complex testing across single or multiple systems from the same interface.

Xena OpenAutomation (XOA), an open-source Python Test Suite, which include XOA Core and test suite plugins is also provided. This comprehensive Python framework offers developers and test specialists well-defined APIs. With XOA Python Test Suites, developers and test specialists can easily harness the power of Xena test systems and effectively handle the configuration and control of the testing equipment making the most of Xena testers with tailored tests and standardized test methodologies like RFC2544, RFC2889 and RFC3918.
