Ethernet’s future has never been brighter. Read how Xena can help you bring new Ethernet products faster to market.

Half a century after its launch, Ethernet is the de facto networking technology for the Internet, industry and data centers. The top speed has grown from 10Mbps to 800Gbps – a factor of 80,000! – and analysts predict the demand for Artificial Intelligence & machine learning (AI/ML), high-performance computing (HPC), and 5G will drive Ethernet speeds from 800Gbps to 1.6Tbps to 3.2Tbps – before 2030!

“Xena will play a key role in this,” says Xena’s CEO, Jacob Vestergaard Nielsen. “Each time the top speed goes up, the race is on to upgrade network equipment. Xena is one of a handful of companies with the test & measurement expertise needed to make it all work.”


If you think 800Gbps Ethernet is fast, just wait!

Devices supporting Ethernet’s new top speed – 800Gbps using 112G SerDes – are now on the market & industry analysts predict the demand for Artificial Intelligence & machine learning (AI/ML), high-performance computing (HPC), and 5G will drive Ethernet speeds to 1.6Tbps to 3.2Tbps – before 2030!

Xena’s product portfolio is carefully tuned to address the needs of companies developing solutions for each of these new technology cycles. With over a decade of experience in this highly specialized field, we are one of the very few companies that can develop scalable, reliable, and intuitive solutions capable of handling the unique challenges of testing terabit Ethernet.


The scalability of our Ethernet TGA solutions is unmatched. Valkyrie can be used for Ethernet validation, Quality Assurance, and production testing, meaning it can meet your test needs throughout the product lifecycle from R&D to when your products ship.

This is also evident in Valkyrie’s unique options for cost-effectively scaling up from very low port counts in the lab to the much higher port density needed in large-scale QA and production testing where rack-space is a premium.

It is also reflected in Valkyrie ability to test all Ethernet speeds. Its unique architecture means it can quickly scale from 1.6Tbps to 3.2Tbps and beyond. This makes transitioning from gigabit-to-terabit Ethernet testing easy and cost-effective thanks to the uniform features, workflows and backwards compatibility that maximize customer convenience.


The transition from gigabit to terabit Ethernet creates new challenges that require new test capabilities.

Transmitting data using PAM-X for 112, 224, and eventually 448Gbps SerDes, over even short distances (e.g. between server racks, or PCB interconnects inside AI modules), seriously deprecates signal integrity. This dramatically increases the need to test Physical Layer performance.

Our new Freya 800Gbps 112G SerDes test modules with their unique Physical Layer test capabilities (see our XenaPHY White Paper) are already meeting the test needs of first-movers among semiconductors, NEMs and hyperscalers as they embrace the new speeds essential for satisfying the unrelenting demand for bandwidth.

We see the need for test equipment that offer powerful Physical Layer testing accelerating year by year, and Xena is committed to helping customers always be ahead of the curve with the test solutions they need outperform their competitors by bringing quality Ethernet products faster to market.


Finally, to complement our expertise in Ethernet TGA we offer Chimera, Xena’s trail-blazing network emulation module. Designed to help 5G O-RAN customers emulate real-world network traffic, Chimera delivers a series of powerful impairment features, enhanced by the unique ability to work seamlessly with Valkyrie’s TGA test modules. Being able to both generate traffic and add impairment via the same interface is an industry-first that radically enhances user convenience and test efficiency.

Combined, these three area of expertise – the unmatched scalability of our TGA, the unique Physical Layer test options and integrated network emulation solution – mean Xena is ideally qualified to help customers develop new Ethernet solutions as each new speed is adopted.
