CHANDLER, Ariz., July 5, 2022 /PRNewswire/ — Viavi Solutions Inc. (VIAVI) (NASDAQ: VIAV) today shared the company’s role at the O-RAN PlugFest, organized by the O-RAN ALLIANCE and hosted by industry leaders. The PlugFest included a series of on-site demonstrations in several countries, conducted in May and May June 2022.

VIAVI was trusted to provide benchmarking and validation for PlugFest tests and demonstrations hosted by the following vendors:

  • AT&T and Dish Wireless at the following locations:
    • COSMOS Laboratory, Rutgers University in New Brunswick, United States of America
    • TIP Community Lab hosted by Meta in Menlo Park, United States of America
    • University of New Hampshire Interoperability Laboratory in durham, United States of America
  • Telefonica a Madrid, Spain; and
  • Auray OTIC and Security Lab in Taiwan.

“The increasing maturity of the O-RAN ecosystem was evident throughout PlugFest,” commented Dr. Ian Wang, CTO Office, VIAVI and Co-Chair, Testing and Integration Focus Group, O-RAN ALLIANCE. “Open Radio Units (O-RUs) are completing fronthaul compliance certification and moving beyond certification into performance testing. There has also been more focus on interoperability in multi-vendor environments beyond the O-RU, with key combinations such as O-RU and Open Distributed Unit (O-DU), O-DU and Open Central Unit (O-CU), and complete end -to-end networks demonstrated Vendors showcased the RAN Intelligent Controller (RIC) and its potential to introduce AI/ML techniques to network optimization and service management. And since the security of open networks is becoming increasingly important, this PlugFest session also included running O-RAN and 3GPP security test cases.”

The VIAVI Test Suite for O-RAN specifications supported conformance, performance, interoperability and end-to-end testing:

  • O-RU – VIAVI and Rohde & Schwarz have partnered on O-RAN Fronthaul (OFH) compliance and 3GPP preconformance testing of O-RUs from Foxconn and other vendors. The two companies also jointly validated an O-RU reference design using components from Analog Devices and Intel. The combined testbed includes the VIAVI TM500 O-RU Tester and the Rohde & Schwarz SMW200A Vector Signal Generator (VSG), FSW Signal and Spectrum Analyzer and Vector Signal Explorer (VSE) software, with the O-RU Test Manager providing a seamless user experience. Separately, VIAVI supported compliance and performance testing of a C-Band 64TRX Massive MIMO Fujitsu O-RU by providing the TM500 O-RU Tester, the TM500 UE Emulator and the T-BERD/MTS 5800 PTP/SyncE Grandmaster.
  • transport – VIAVI also deployed the T-BERD/MTS-5800 for Xhaul transport and synchronization testing on ADVA’s FSP 150-XG418 as Cell Site Gateway (CSG) and Ensemble Activator Network Operating System (NOS) on Edgecore AS7316-26XB as hub site Router (HSR) and validation of third-party optical connector compatibility from Precision Optical Transceivers.
  • End-to-end interoperability and security testing – VIAVI TM500 UE Emulator and TeraVM Core Emulator were used for E2E and security testing of multiple vendor combinations including: Foxconn O-RU and REIGN CORE; the Pegatron O-RU, O-CU and O-DU; and equipment from ASKEY.
  • R.I.C – VIAVI demonstrated near real-time benchmarking of RIC platform performance by integrating a third-party xApp into the VIAVI TeraVM RIC test. The two companies also partnered to demonstrate traffic control in near real-time RIC by integrating anomaly detection, quality prediction and traffic control xApps with the TeraVM RIC test in a fully automated, cohesive manner and cross-vendor-technical environment .

“Interest in cross-industry collaboration at O-RAN has grown so much that we have moved to several PlugFest sessions throughout the year,” he said Stephen Rent, Vice President of Wireless Marketing, VIAVI. “Beyond the number of participants, complexity is introduced in terms of end-to-end interoperability, AI and ML-driven automation in assurance and optimization, and security. VIAVI has enabled our partners to overcome this complexity by delivering comprehensive and relevant test cases on proven platforms known for ease of use and fast results.”

VIAVI offers the market’s most comprehensive test suite for laboratory validation, field deployment, and service assurance of O-RAN networks. With extensive experience in validating network products for operators and manufacturers worldwide, VIAVI enables any node – O-RU, O-DU, O-CU, RIC and Core – to be run and complete end-to-end on-site testing to be performed in the cloud or as a service.
