VIAVI has published the details of a recent O-RAN PlugFest
VIAVI and Rohde & Schwarz partnered on O-RAN Fronthaul (OFH) conformance and 3GPP pre-conformance testing of O-RUs from Foxconn and other vendors. They also jointly validated an O-RU reference design with 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 conformance and performance testing of a C-Band 64TRX Massive MIMO Fujitsu O-RU, providing the TM500 O-RU Tester, TM500 UE Emulator and T-BERD/MTS 5800 PTP/SyncE grandmaster.
VIAVI also provided the T-BERD/MTS-5800 for Xhaul Transport and Synchronization testing on ADVA’s FSP 150-XG418 as a Cell Site Gateway (CSG) and Ensemble Activator network operating system (NOS) on Edgecore AS7316-26XB as a Hub Site Router (HSR), and validating the compatibility of third-party optics plugs from Precision Optical Transceivers.
The VIAVI TM500 UE Emulator and TeraVM Core Emulator were used for E2E and security testing of multiple vendor combinations, including: the Foxconn O-RU and REIGN CORE; the Pegatron O-RU, O-CU and O-DU; and equipment from ASKEY.
VIAVI demonstrated near real-time RIC platform performance benchmarking by integrating another vendor’s xApp with the VIAVI TeraVM RIC Test. The two companies also partnered to demonstrate traffic steering in near real-time RIC by integrating anomaly detection, quality prediction and traffic steering xApps with the TeraVM RIC Test, in a fully automated, closed-loop fashion, and in a multi-vendor, multi-technology environment.
