VIAVI Selected as Testing Partner for Korea’s O-RAN Lab

SCOTTSDALE, Ariz., April 12, 2022 /PRNewswire/ — Viavi Solutions Inc. (VIAVI) (NASDAQ: VIAV) today announced that it has been selected as an O-RAN test and measurement partner in a test and certification lab, jointly operated by the Korean organizations Telecommunications Technology Association (TTA) and the Electronics and Telecommunications Research Institute (ETRI).

VIAVI provides its TM500 O-RU tester, which provides conformance testing, O-RAN front-end transport layer testing, and 5G physical layer testing to validate performance and interoperability. The TM500 O-RU tester supports O-RAN WG 4 specifications as well as 3GPP version 38.141 – 1.

The growth of Open RAN has become a global phenomenon as operators and vendors around the world have embraced the evolving standards. As the standards allow multiple vendors, new and old, to supply equipment for different parts of the 5G network, this makes conformance and interoperability testing more critical than ever.

VIAVI offers the industry’s most comprehensive test suite for lab validation, field deployment, and service assurance of O-RAN networks. With extensive experience validating network products for carriers and manufacturers worldwide, VIAVI enables any node – O-RU, O-DU, O-CU, RIC and Core – and tests complete end-to-end to be done on-premises, in the cloud or as a service.

“O-RAN’s growth is a great leveler when it comes to communications infrastructure providers,” said Younghae Choi, president of TTA. “Where there used to be two or three major vendors, there are now literally hundreds of vendors all vying for their place in the network and innovating to deliver what the market needs. This new multi-vendor environment makes testing more compliance and interoperability issues and we are grateful to VIAVI for their important role in supporting our efforts in the Korean market.”

“Korea has been one of the world’s innovation hotspots for many years,” said Rajesh RaoVice President, Asia Pacific and Japan, VIAVI. “When you look below the surface, you see the vital work of organizations like the TTA and ETRI to maintain Korea’s leadership in innovation. We are proud to support both the TTA and the ETRI, as they help prepare Korean vendors and the wider ecosystem for the growth of O-RAN-based networks.”
