Viavi’s Test Suite is Receiving an O-RAN Upgrade

The new and improved test suite from Viavi Solutions will help operators validate network products that follow the guidelines of the O-RAN Alliance. Upgrades include critical case uses and learnings from working with customers on Open RAN and 2020 plugfest learnings. The new space will bring components from a range of vendors, however, the responsibility of conformance, interoperability, and performance falls on vendors. Some of the specific upgrades seen for the test suite include O-RAN Subsystem, End-to-End testing, and transport network testing to name a few.

Confident in its test suite, Viavi and Rhode & Schwarz are collaborating to showcase validation of open fronthaul performance with the O-RAN Alliance in MWC Shanghai. Rhode & Schwarz will use their vector signal generator and signal and spectrum analyzer hardware to perform RF signal generation and capture, alongside VSE Software for signal analysis. Speaking on the changes, Viavi’s Chief Technology Officer Sameh Yamany said, “The promise of O-RAN extends beyond the many benefits of an open ecosystem to include a solid foundation for virtualized network elements, enabling increased speed and scalability to capture the burgeoning 5G market. Yet the complexity of multi-vendor O-RAN architecture presents significant challenges for successful network development, deployment, and operation, requiring thorough validation, integration, and troubleshooting with a complete set of advanced test solutions.”

Viavi is moving its headquarters to Chandler, Arizona, and is making a new manufacturing plant with a focus on the Optical Security and Performance Products segment of its business. In January 2021, Viavi confirmed that it will be working with Mavenir for testing cloud-native RAN solutions by using the vendor’s lab test platform. There are more than 200 service providers with a history of working with Viavi who assists in validating network products. Involved in multiple working groups within the O-RAN Alliance, the move makes complete sense for Viavi. The company is also looking into developing various O-RAN specifications such as the editor of interoperability test specifications in open fronthaul and open interfaces working groups.
