San Jose, Calif., October 28, 2020 – VIAVI Solutions Inc. (VIAVI) (NASDAQ: VIAV) today announced the company successfully participated in a global O-RAN plugfest hosted by several Tier-1 communications service providers (CSPs) and the O-RAN ALLIANCE. The plugfest involved a series of on-site demonstrations in multiple countries, conducted in September and October 2020. VIAVI provided industry-leading 4G and 5G test and validation platforms to support the worldwide event, which demonstrated key Open Radio Access Network (O-RAN) use cases involving a number of network equipment manufacturers (NEMs) and system integrators, accelerating the commercialization of O-RAN and diversification of the RAN supply chain.

In a multi-vendor based O-RAN environment, ensuring interoperability will become the network operator’s principal concern. The VIAVI Test Suite for O-RAN Specifications offers comprehensive, integrated solutions to validate that all interfaces are working correctly – including RF, signaling and interoperability, timing and synchronization – and equipment is performing to specifications even under load and stress. In the lab, the TM500 and TeraVM families deliver UE, O-RAN subsystem and core network simulation to enable conformance, interoperability and performance testing of both complete base station and core network testing as well as wraparound testing of individual O-RAN subsystems and core network elements. In both the lab and the field, T-BERD/MTS-5800 validates critical synchronization parameters with necessary precision using its Timing Extension Module (TEM), delivering a highly stable reference signal for synchronizing test equipment and O-RAN components. CellAdvisor 5G characterizes and analyzes 4G and 5G RF signals. ONT-800 tests transport network performance up to 800G.

VIAVI supported the following plugfests:

• Berlin, Germany. This plugfest was hosted by Deutsche Telekom, with demonstrations of radio access equipment from Baicells, Benetel, Foxconn, QCT, Wind River, Wiwynn and other vendors. VIAVI provided the TM500 including UE emulation for performance testing and O-DU emulation for O-RU subsystem testing; TeraVM for core emulation and traffic generation; MTS-5800 for transport and synchronization test; and CellAdvisor 5G for RF signal analysis.

• Torino, Italy. This plugfest was hosted by TIM, with demonstrations of radio access equipment from Commscope, WNC, Wiwynn and other vendors. VIAVI provided the MTS-5800 for timing and synchronization.

• Madrid, Spain. This plugfest was hosted by a major Spanish service provider, with demonstrations of O-RAN x-haul (fronthaul and midhaul) transport with equipment from multiple vendors. VIAVI provided the MTS-5800 for timing and synchronization, and ONT-800 for multi-port transport test.

• Bengaluru, India. This plugfest was hosted by Airtel, with demonstrations of multi-vendor integration of O-RAN compliant radio access software and equipment from Altiostar, NEC, VVDN and Xilinx. The VIAVI TM500-C-5G 5G NR UE emulator and TM500 O-RU emulator were used for in-depth verification of the O-DU’s compliance to the WG4 open fronthaul (C/U/S planes) specification.

• Tokyo, Japan. This plugfest was hosted by Japanese service providers, with demonstrations of radio equipment from major O-DU/O-CU and O-RU vendors. VIAVI provided the TM500 for 5G NR UE emulation.

"As a champion of interoperability test methodologies, and the first company to introduce a comprehensive test suite for O-RAN specifications, VIAVI has worked closely with ecosystem partners and operators worldwide to help identify, isolate and resolve performance issues with disaggregated networks," said Sameh Yamany, Chief Technology Officer, VIAVI. "The successful results of the global O-RAN ALLIANCE plugfest represent a significant step forward in the advancement of multi-vendor O-RAN environments, which are essential to scaling and sustaining 5G networks."

Scottsdale, Ariz., May 25, 2021 – Viavi Solutions Inc. (VIAVI) (NASDAQ: VIAV) today announced availability of the TeraVM O-CU Tester on AWS Outposts, marking the industry’s first O-RAN Central Unit (O-CU) test solution deployed on Amazon Web Services (AWS) Managed Services (AMS) at the network edge. As 5G services leverage edge computing, the ability to validate application and infrastructure performance at any point in the network has become essential to ensuring quality of experience.

In order to monetize 5G investments, service providers, device manufacturers, and application developers are striving for new paradigms in user experiences. Real-time, multi-player games, smart cities, autonomous cars, and remote healthcare all require ultra-low latencies, which ultimately can be enabled by 5G Ultra Reliable Low Latency Communication (URLLC) and Multi-access Edge Computing (MEC). In parallel, operators worldwide are adopting open radio access networks to reduce infrastructure costs and lower the barrier to entry for new product innovation.

To address this emerging domain, VIAVI has deployed the TeraVM O-CU Tester on AWS Outposts. Within the architecture of disaggregated networks, the O-CU is a critical resource as the first point in the uplink from end users, where large amounts of traffic converge and need to be handled efficiently in order to meet performance expectations. The O-CU Tester – part of the TeraVM family of fully virtualized and cloud-enabled network and application test solutions – validates that the O-CU works according to 3GPP standards and O-RAN C-plane and U-plane profiles; interoperates with other 5G and O-RAN network functions and components; and performs optimally when fully loaded with complex mobile traffic profiles.

AWS Outposts is a fully managed service that offers the same AWS infrastructure, AWS services, APIs, and tools to virtually any data center, co-location space, or on-premises facility for a truly consistent hybrid experience.

"Our major customers are embracing the power of the cloud and 5G, unleashing rich applications for consumers, businesses and cities," said Ian Langley, Vice President and General Manager, Wireless Business Unit, VIAVI. "We’re pleased to work alongside them to validate application performance at any point in the network and welcome the collaboration with AWS."
