The VIAVI NITRO Wireless Open RAN Radio Unit Development solution uses the TM500 O‑RU Tester to simplify evaluation of Open RAN radio units, which handle lower physical layer and RF functions in a disaggregated architecture. Vendors must prove not only standards compliance but also real‑world interoperability and performance comparable to traditional 5G radios to gain operator acceptance. The TM500 O‑RU Tester provides a controlled environment to validate functionality, performance, and integration with other Open RAN components, helping vendors accelerate development and demonstrate readiness for deployment.
