Viavi Solutions has delivered 5G O-RAN fronthaul and optical transport test systems to China Mobile Research Institute (CMRI), the research division of the world's largest mobile operator, China Mobile.
As fifth-generation commercial deployments continue to ramp up, and multi-vendor, disaggregated architectures emerge, the need for performance validation and service assurance becomes ever more critical. As a preferred vendor, VIAVI has worked closely with China Mobile for several years to validate the performance of 5G infrastructure – from early days in 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 fifth-generation 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.
