[Barcelona, Spain, March 1, 2026] During MWC26 Barcelona, Huawei will announce a comprehensive upgrade to its 5G-A mobile transport network with the launch of the Fiber Health Care (FHC) solution. As a pivotal upgrade for 5G-A mobile transport, this solution provides a robust foundation for emerging services such as high-definition live streaming and mobile XR. Simultaneously, it establishes high-reliability network capabilities to ensure a smooth evolution toward 6G. By integrating built-in OTDR (Optical Time-Domain Reflectometer) and Self-Diag algorithms, the solution enables automated detection and minute-level fiber fault localization without the need for manual site visits—helping operators reduce O&M costs and enhance network reliability.
In the Agentic MBB era, high-quality network infrastructure serves as the cornerstone for 5G-A services—such as HD live streaming, mobile XR, and industrial control—as well as future 6G validation. Consequently, the quality of fiber optics directly dictates the overall performance of the network. However, the current average global fiber failure rate stands at 3%. In certain areas, the failure rate exceeds 5% due to a combination of factors, including substandard fiber burial, frequent damage from construction activities, and natural ‘non-destructive’ aging of the fiber. Traditional maintenance relies heavily on technicians carrying external instruments and visiting sites 3 to 4 times for troubleshooting. This process typically takes 2 to 3 days, this has brought huge maintenance costs to operators.
Huawei 5G-A Mobile Transport Provides Comprehensive Fiber Health Care, Reshaping Network Resilience to Ensure Zero Service Interruption During Fiber Cuts
To tackle this persistent challenge, Huawei has upgraded its Fiber Health Care solution for 5G-A mobile transport networks. The solution is built upon three core capabilities:
- Instrument-Free Detection, O&M Costs Saving By leveraging built-in OTDR (Optical Time Domain Reflectometer) capabilities within the equipment, the FHC solution moves away from the traditional “meter-dependent, repeated site visit” model. Regardless of whether services are online, detection can be triggered via device configuration or the NCE network digital map. This allows for the precise identification of fiber breaks, aging, or poor splicing. For a typical operator, this solution is projected to save millions of dollars in annual maintenance costs.
- Meter-Level Precision and Minute-Level Visibility Powered by Self-Diag optical signal noise reduction and high-precision analysis algorithms, the equipment gains the ability to “see” fiber health. The solution supports a detection range of up to 80 kilometers with meter-level precision. It provides a detailed analysis of fault types and distances within minutes. Furthermore, fault points are mapped directly onto a GIS (Geographic Information System) via the NCE network digital map, guiding maintenance teams to the exact location and improving overall O&M efficiency by 20%.
- Fiber fault, No Service Interruption and Ensuring User Experience By deploying end-to-end SRv6 (Segment Routing v6), the solution enables full-scenario protection switching. In the event of a fiber failure, the network can flexibly reschedule traffic within minutes to prevent congestion and maintain a “zero-congestion” state, ensuring the user experience remains unaffected.
Huawei stated that this solution represents a pivotal milestone in the evolution of 5G-A mobile transport networks toward 6G. By leveraging high-reliability fiber health monitoring, the solution is designed to guarantee superior user experiences for emerging services and establish a future-proof network foundation. Ultimately, it empowers operators to build automated, highly resilient IP transport networks that safeguard service quality in the Agentic MBB era.
