Viavi Solutions announced that its TTworkbench software and TestCenter M1 Appliance have been recognized as an Avnu Certification Test Tool (CTT) by the Avnu Alliance. The certification allows the tools to be used for verifying compliance with IEEE 802.1AS standards within the Avnu Component Certification Program, streamlining Time‑Sensitive Networking (TSN) validation for customers.
The certification is part of Viavi’s strategy to support the expanding TSN market, which is growing across automotive, industrial automation, professional audio, aerospace, and defense. By combining automated TSN conformance testing with high‑precision traffic generation and timing analysis, Viavi’s solution reduces complexity, accelerates certification timelines, and enables multi‑vendor interoperability testing.
Management highlighted the significance of the recognition. Aniket Khosla, Vice President of Product Management, Lab and Production, said the certification "underscores the strength of VIAVI's unified approach to TSN validation. By combining automated TSN conformance testing with high‑precision traffic generation and timing analysis, our solution enables customers to accelerate certification cycles while gaining greater confidence in multi‑vendor interoperability." Jeremy Rover, Co‑Chair of the Avnu Alliance Certification Working Group, noted that adding Viavi’s CTT "expands access to trusted tools that support efficient certification workflows and help device manufacturers and test labs accurately reflect product conformance to Avnu test plans."
The certified tools will be showcased at the Avnu Alliance Plugfest in London from April 20‑24, 2026, where participants will demonstrate the integrated workflow and validate the tools against Avnu conformance test plans. The certification expands Viavi’s portfolio of Avnu CTTs, positioning the company as a key player in the TSN ecosystem and potentially opening new revenue opportunities in sectors that require deterministic Ethernet communication.
While the announcement does not include immediate financial metrics, the certification is expected to strengthen Viavi’s competitive position in the TSN market and support future growth in its test and measurement business. The move aligns with industry trends toward standardized, interoperable networking solutions and may drive increased demand for Viavi’s TSN validation tools.
