Next-gen test and measurement solutions specialist VeEX has formally introduced its second generation RXT-6400 Advanced 400G test set. The latest iteration provides native PAM4 support for OSFP and QSFP-DD transceivers.

The new RXT-6400 module, which is shipping to key customers, is based on the latest generation of flexible, state-of-the-art 58G PAM4-based FPGA technology. This native PAM4-based product is designed to enable best-in-class signal integrity (no adapters required) and allow the test set to continue adapting to evolving 400GE technology. In addition, it addresses common 100GE and below applications, in keeping with proven forward-looking principles of the contractor’s RXT-1200 test platform.

Key improvements added to the 2nd generation RXT-6400 include:

  • OSFP cage (in addition to QSFP-DD)
  • Dual ports for 100G and below (future-proofing)
  • OSFP and QSFP-DD case temperature monitor (in addition to transceivers’ internal sensors)
  • Transceiver power consumption measurement (in addition to variable voltage supply)
  • Eye clock reference and recovered clock outputs
  • Improved interoperability
  • Improved cooling.

Overall, the new RXT-6400 module supports multiple PAM4 and NRZ data rates from 1GE to 400GE, with OSFP, QSFP-DD, QSFP56, QSFP28, QSFP+, SFP28, SFP+, and SFP and 1000BASE-T (SFP) transceivers. A true handheld with battery operation, the RXT is used to reduce testing time at large datacentres and aggregation nodes.

“Back in 2018, VeEX pioneered the 400G PAM4 lab-to-field transition with the introduction of the RXT-6400, the first and only handheld tester with native QSFP-DD support. The RXT-6400 opened many doors for us and allowed us to have open conversations with NEMs, transceiver manufacturers, datacentres, and service providers. This allowed us to understand PAM4’s state-of-the-art technology, foreseeing the challenges and technology trends,” said Ildefonso M. Polo, VP of Product Marketing for VeEX. “We listened to all of the suggestions and experiences from R&D, SVT, FAEs and lab evaluation teams, and decided to build an improved second generation RXT-6400 test set to address them and offer a better solution for current and future requirements. For example, adding native support for OSFP makes it more flexible, future-proof and helps us address wider markets and applications.”
