400GE FEC Measurements

Interoperability a critical requirement in performance testing of 400GE solutions

A key player in the Chinese telecommunications industry needed a 400GE traffic generation and analysis solution for performance testing of new standards and technology.

Critical requirements for the solution was the capability to do FEC measurements, and it needed to be compatible with 400GE transceivers from major vendors. Ease of use and
price/performance were also important considerations.

Seven-speed Thor 400GE Test Module

Competing against various solutions from market leaders in a public tender process, the state-run lab finally chose Xena’s ValkyrieBay chassis with two Thor 400GE test modules.

The Thor-400G-7S-1P test modules are capable of generating full line rate 400GE traffic, while FEC measurements are easy to do using the ValkyrieManager software. In addition to 400GE, Thor-400G-7S-1P can also generate 200GE, 100GE, 50GE, 40GE, 25GE and 10GE traffic.

Finally, they have also been tested for interoperability with many of the major transceiver vendors at, for example, the 400G Plugfest conducted by the University of New Hampshire’s Interoperability Lab.

“This was an important strategic win for Xena,” explains Owen Chen, Xena’s Sales Director in APAC. “Given the customer’s role in China’s telecommunications industry, this will influence subsequent sales of other Valkyrie, Vulcan and Chimera.”

A leading ODM specializing in FPGAs and NICs had a large R&D facility in India. Acting on the recommendation of a US-based FPGA partner, they requested an evaluation of Xena’s Valkyrie platform to test their FPGAs at 100GE. This testing required multiple stream generation capabilities and RFC2544 testing.



A major equipment manufacturer in China’s digital information and TV industry needed a production line test solution for Quality Assurance (QA) of 1GE PON devices. The solution needed to support long tests – up to 72 hours – as well as production tests taking just 10 seconds. Having experienced reliability issues with their previous solution, the manufacturer needed a production line tester that generated consistently accurate results.
