Viavi Solutions announced that the company has delivered 5G O-RAN fronthaul and optical transport test solutions to China Mobile Research Institute (CMRI), the research division of the world's largest mobile operator, China Mobile. As a preferred vendor, VIAVI has worked closely with China Mobile for several years to validate the performance of 5G infrastructure, from the lab to field deployment and operations. This collaboration includes development of Slicing Packet Network (G.MTN) with FlexE interface technology for next-generation 5G transport.
In the next phase of G.MTN advancement, VIAVI has delivered the ONT-800 Optical Network Tester for CMRI to conduct performance testing and validation of G.MTN interfaces and related protocols. By leveraging network slicing in their 5G transport network, China Mobile benefits from key advantages of G.MTN technology, such as high bandwidth, low latency, ultra-high precision synchronization, software-defined centralized management, and scalability.
Additionally, VIAVI has provided China Mobile with the VIAVI T-BERD/MTS-5800 100G network tester for O-RAN link analysis in the 5G fronthaul network. The T-BERD/MTS-5800 network tester enables China Mobile technicians to conduct end-to-end system testing, fault isolation and root cause analysis, as well as single-vendor and cross-vendor interoperability testing — a crucial capability when deploying open, multi-vendor O-RAN infrastructure.
