Eridan completed integration of its 5G Open RAN radio platform with the latest release of the OCUDU open-source CU/DU software stack in less than one day, using standard O-RAN interfaces exclusively. The company, based in Sunnyvale, California, announced the result on June 30, 2026.

The speed of the integration is the story. Open RAN's core promise has always been that radios and baseband software from independent vendors can interoperate through published interfaces without bespoke engineering. Eridan and OCUDU claim to have demonstrated exactly that, on a commercial platform rather than in a lab showcase.

"Integrating with the latest OCUDU release in less than a day demonstrates the progress the industry has made in achieving Open RAN interoperability," said Omid Tahernia, CEO of Eridan. "Open interfaces only matter if independent platforms can work together in practice."

What was actually integrated?

The combined platform pairs OCUDU's central unit/distributed unit (CU/DU) software with Eridan's Ultra-Clean Signal radio technology. Eridan's radios use a fully digital, low-power direct polar architecture that the company says delivers carrier-grade 5G performance at a fraction of the energy footprint of conventional equipment.

That energy claim is vendor marketing until independent operator trials validate it. What is verifiable today is the integration record: Eridan has now connected its radio platform with 15 distinct CU/DU solutions and is contributing to interoperability testing and feature validation within the OCUDU project.

The integrated platform targets a deliberately wide set of use cases:

• Mobile operator networks
• Private 5G deployments
• Government systems and defense
• Utilities and critical infrastructure

The breadth signals where Eridan sees near-term demand — private networks and government buyers have historically been faster to adopt Open RAN than tier-one public carriers.

Why does open-source CU/DU software matter?

OCUDU goes a step beyond the usual Open RAN interoperability argument. Where most Open RAN efforts focus on standardizing the interfaces between components, OCUDU makes the CU/DU software itself open source. The stack provides a common software foundation for testing, validation, feature enhancement and AI-RAN applications across the ecosystem.

The OCUDU Ecosystem Foundation, hosted by the Linux Foundation, describes its mission as building a commercial and research ecosystem around a production-ready open-source CU/DU stack. It supplies reference architectures, conformance tooling and what it calls "super blueprints" intended to move Open RAN from pilot projects to global production.

The project carries weight in US policy circles. Dr. Tom Rondeau, Principal Director of FutureG at the Office of the Under Secretary of War for Research and Engineering, framed the Eridan integration as evidence that the model works.

"OCUDU was created to provide a shared, interoperable software foundation for Open RAN development — acting as a transformative catalyst for the telecommunications industry," Rondeau said. "The pairing by Eridan of this open-source CU/DU software stack with their low-power direct polar architecture is proof that the Open RAN ecosystem can rapidly deliver scalable, carrier-grade performance through innovations from U.S. commercial industry."

What is the defense angle?

Rondeau's remarks place the Eridan integration squarely in the context of US Department of War edge deployments. He said he is "excited to see how Eridan's solution can significantly reduce the energy footprint and infrastructure costs required for both advanced commercial 5G and tactical DoW deployments at the edge."

That dual-use framing matters commercially. A radio vendor that can point to both carrier-grade Open RAN interoperability and low power consumption suited to tactical edge operations addresses two procurement pipelines at once — commercial operators weighing energy costs and defense buyers constrained by power and weight budgets at forward locations.

What happens next?

"We are proud to bring to market a commercial 5G solution that pairs our Ultra-Clean Signal radio technology with the powerful open-source OCUDU software stack," Tahernia said. Eridan says it will continue contributing to interoperability testing and feature validation within the OCUDU project, which is positioning its stack as the reference software layer for scaling Open RAN beyond pilots.
