How to use Huawei optical module routers

To connect an optical module to a Huawei router, insert the module into the optical port, connect the optical fiber correctly, and configure the interface if necessary.Physical InstallationInsert the Optical Module: Gently push the optical module into the router's optical port until you hear a click. If it does not fit, do not force it; turn the module 180 degrees and try again .Dust Protection: Remove the dust plug from the module before connecting fibers and keep it in a safe place. Install dust plugs on unused ports to prevent contamination .Fiber Connection: Remove dust caps from the fiber connectors. Connect one end of the fiber to the optical module and the other to the remote device. Ensure the receive (RX) and transmit (TX) ends are correctly aligned according to the module's identifiers .Labeling: Temporarily label both ends of each fiber to avoid confusion, then replace with formal labels after installation .Configuring Combo InterfacesIf your Huawei router has a Combo interface (optical-electrical multiplexing), only one port (optical or electrical) can be active at a time . To enable the optical mode:Enter system view on the router.Execute the command: interface Switch to optical mode with: combo enable fiberTo revert to electrical mode: undo combo enable fiberEnsure the same configuration is applied on the peer device .Verification and TroubleshootingCheck Module Compatibility: Ensure the optical module matches the router port type and fiber type (single-mode or multi-mode) and does not exceed the interface speed .Check Optical Power: Measure the input optical power to ensure it is within the normal range to prevent module damage .Interface Status: Use commands like display interface or display transceiver interface verbose to verify the module is recognized and operational .Loopback Test: If the connection fails, perform a loopback test by connecting the fiber jumper to the same module to check for abnormalities . Following these steps ensures a safe and functional connection of optical modules to Huawei routers, whether for standard optical ports or Combo interfaces.
