How to configure Huawei s optical module

Configuring a Huawei optical module involves proper installation, enabling the optical interface, verifying module compatibility, and checking operational status using display commands.Physical InstallationSafety First: Never look directly into the optical module or fiber ends, as laser radiation can cause eye damage. Wear an ESD wrist strap or gloves to prevent electrostatic discharge damage .Insert the Module: Remove the dust plug from the optical port, ensure the module is correctly oriented, and gently push it into the port until it clicks. If it does not fit, rotate 180° and try again .Check Seating: Keep the handle closed and gently pull the module. If it does not come out, it is properly seated .Fiber Connection: Only connect optical fibers after the module is installed. Measure input optical power to ensure it is within the safe range .Enabling the Optical InterfaceFor Combo interfaces (optical/electrical), enter system view and execute:CodeCopyinterface combo enable fiber to switch to the optical interface. Use undo combo enable fiber to revert to electrical mode .For 10GE optical ports, execute:CodeCopyport combination-mode 10GE interface to switch from default 2.5GE electrical mode to 10GE optical mode. Reverting is done with undo port combination-mode 10GE interface .Verifying Module CompatibilityEnsure the optical module matches the port speed and fiber type (single-mode vs. multi-mode). Do not mix incompatible fibers or use a higher-speed module than the interface supports .Only use Huawei-certified modules to ensure reliability. Non-certified modules may fail to install or operate correctly .Checking Module StatusUse the following commands to read module information and diagnostics:CodeCopydisplay transceiver interface verbosedisplay transceiver diagnosis interface display interface These commands provide details on transceiver type, wavelength, optical power, link status, and digital diagnostic monitoring (DDM) data .To view all interfaces and their status:CodeCopydisplay interface brief TroubleshootingIf the port shows Administratively DOWN, enable it using:CodeCopyinterface undo shutdown Perform a loopback test by connecting the fiber jumper to the same module to check for abnormal conditions .Verify that received and transmitted optical power is within normal range using the display transceiver command . By following these steps, you can safely install, configure, and verify Huawei optical modules, ensuring proper operation and network stability.
