Xena Networks - Z100 Loki for testing Ethernet traffic of NRZ speeds: 10G / 25G / 40G / 50G / 100G

In Nordic mythology, Loki is the god of mischief. In the world of Ethernet testing, Z100 Loki is an important part of the Xena product line, which is Xena’s Ethernet Traffic Generation & Analysis (TGA) solution.

Z100 Loki supports testing of NRZ-based Ethernet at data rates of 10G / 25G / 40G / 50G / 100G.

In the Xena line we also have Z10 Odin (NRZ testing 10Mbps to 10G), Z400 Thor (NRZ testing 10 to 100G and PAM4 testing 50G to 400G), Z800 Freya (10G NRZ to 800G PAM4) and the Z1608 Edun (112G & 224G SerDes) which can generate up to 1.6Tbps.

Speeds and technology

Z100 Loki uses NRZ technology. NRZ modulation has been used for Ethernet signals sent over data lines for many years. NRZ stands for “non-return to zero” – a modulation technique for serial communications that uses two voltage levels to represent logic 0 and logic 1. Z100 Loki supports Ethernet testing of NRZ data rates of 10G / 25G / 40G / 50G / 100G.

Hardware

There are two Z100 Loki test modules (see table below) – one with 2 ports, the other with 4, and both available in Xena’s fixed 1U chassis: the XenaCompact. Or they can be used in the modular 4U XenaBay chassis.

Software

All Xena solutions include 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.

Add Impairment Emulation with E100 Chimera

Many factors can impede data traffic as it crosses different networks. Network emulators are a cost-effective tool for helping verify if equipment can handle real-world conditions. That’s why the Xena Ethernet Test Platform also includes the E100 Chimera, a network emulation test module that makes it easy to emulate multiple forms of latency, jitter and other forms of impairment to Ethernet traffic.

E100 Chimera supports full wire-speed impairment at five speeds up to 100Gbps and works seamlessly with Xena traffic generators, allowing you to both generate and impair traffic via the same XenaManager GUI – a feature unique to the Xena platform.
