Connect the fiber optic interface to the Xiaomi router

To connect a Xiaomi router to a fiber optic connection, you must first link the fiber line to an Optical Network Terminal (ONT) and then connect the ONT to your router via Ethernet.Required Equipment

• Optical Network Terminal (ONT): Converts the fiber optic light signal into an electrical signal your router can use, usually provided by your ISP .
• Xiaomi Router: Ensure it has a WAN port or supports SFP modules if using direct fiber input .
• Ethernet Cable: Cat6a or higher is recommended for optimal speeds .
• Fiber Optic Cable: Typically single-mode with SC/APC or SC/UPC connectors .

Step-by-Step Connection

1. Install the ONT: Place it near the fiber entry point in your home, close to a power outlet. Connect the fiber optic cable from the wall outlet to the ONT's optical port, handling the cable carefully to avoid damage .
2. Connect ONT to Router: Use an Ethernet cable to link the ONT's LAN/Ethernet port to the Xiaomi router's WAN port. If your router supports SFP modules, insert the module and connect the fiber directly if required .
3. Power Up Sequence: First, plug in the ONT and wait for it to establish a connection with your ISP. Once the ONT is stable, power on the Xiaomi router .
4. Router Configuration: Access the Xiaomi router's web interface (usually 192.168.31.1). Configure the WAN connection type as PPPoE if your ISP requires a username and password, or select Dynamic IP if credentials are not needed . Enter the PPPoE credentials provided by your ISP if applicable.
5. Verify Connection: Check the router's status lights and the ONT indicators. A solid green light on both devices usually indicates a successful connection .

Tips for Optimal Performance

• Place the router in a central, well-ventilated location to maximize Wi-Fi coverage.
• Use high-quality Ethernet cables to prevent speed loss.
• Enable QoS settings on the Xiaomi router if you use VoIP or streaming services to prioritize traffic .
• If the connection fails, ensure the fiber cable is properly seated in the ONT and that the ONT has completed its boot sequence before powering the router . By following these steps, your Xiaomi router should successfully connect to your fiber optic internet, providing high-speed and stable network performance.
