Check the optical module of the OLT

You can view OLT optical module information using CLI commands to check module type, wavelength, transmission distance, and real-time diagnostics, or via OLT dashboards for monitoring system health and optical parameters.Using CLI Commands on Huawei OLTsTo check an optical module on a Huawei OLT or switch interface:Basic Interface Status Run the command: display interface This shows interface rate, module type, link status (UP indicates normal operation), and traffic statistics, which are useful for troubleshooting .Detailed Optical Module Information Use: display transceiver interface verbose This command provides two main sections:Module Identification: Type, operating wavelength, transmission distance, serial number, manufacturer, and connector type.Digital Diagnostic Monitoring (DDM): Real-time parameters such as receive/transmit power, temperature, voltage, and bias current, along with threshold ranges .Diagnostic Check For troubleshooting, run: display transceiver diagnosis interface This displays DDM information and helps identify faults or abnormal optical power levels .Using OLT DashboardsFor GPON or XGS-PON OLTs, dashboards provide a graphical view of optical module status:System Health: CPU and memory utilization at the OLT level.Traffic Monitoring: Uplink and PON port traffic utilization.Optical Monitoring: Environmental health metrics, including optical power and module degradation indicators.Dashboards allow early detection of optical module issues and help maintain network performance .Best PracticesEnsure the module is vendor-certified to avoid compatibility issues.Regularly monitor receive and transmit power, temperature, and voltage to prevent service degradation.Use both CLI and dashboard tools for comprehensive monitoring, especially in large PON deployments . By combining CLI commands and dashboard monitoring, you can effectively view and manage OLT optical module information, ensuring optimal network performance and early detection of potential faults.
