VIAVI and Calnex launch integrated Open RAN testing solutions

CHANDLER, Ariz. - VIAVI Solutions Inc. (NASDAQ:VIAV), whose stock has surged nearly 94% over the past six months and is trading near its 52-week high of $17.99, has partnered with network synchronization specialist Calnex Solutions plc to develop comprehensive test solutions for Open RAN products across protocol, signal and timing domains.

The collaboration aims to simplify pre-certification validation for Open RAN equipment manufacturers by providing plug-and-play testbeds that require no debugging and can be implemented immediately. This strategic move comes as VIAVI, with a market capitalization of approximately $3.9 billion, continues to strengthen its position in the telecom testing market.

The partnership offers three ready-to-use testbeds: an end-to-end and cybersecurity test solution for fronthaul and midhaul, an O-RU and O-DU test solution with S-plane testing, and core network emulation test bundles for backhaul.

These integrated systems allow for full O-RAN ALLIANCE and 3GPP conformance testing, including key WG4, WG5, and TIFG specifications, while emulating realistic network conditions such as jitter and delay.

"During the development phase, many O-RUs are only tested with a single O-DU/O-CU vendor, which results in failure under real-world network conditions," said Ian Langley, Senior Vice President and General Manager of VIAVI’s Wireless Business Unit, according to a company press release.

Tommy Cook, CEO of Calnex, noted that establishing in-house labs for Open RAN validation has traditionally required equipment from multiple vendors and months of debugging to ensure interoperability.

The solutions combine VIAVI’s TM500 and XEdge test platforms with Calnex’s hardware, including Paragon-neo for synchronization testing and SNE-Ignite for network impairment emulation.

The companies stated that additional testbeds are in development as the telecom industry continues its shift toward Open RAN and AI-RAN in 5G and 6G systems.

In other recent news, Viavi Solutions reported impressive fiscal first-quarter 2026 results, with revenue reaching $299 million, marking a 25.6% increase year-over-year. This figure surpassed both management guidance and consensus estimates of $294 million.
