You cannot plug a fiber optic cable directly into a standard router; you need an Optical Network Terminal (ONT) or a media converter to convert the optical signal to Ethernet.

Required Equipment

• Optical Network Terminal (ONT): Converts the fiber optic light signal into an electrical signal compatible with Ethernet ports, usually provided by your ISP .
• Router: Ensure it has a WAN or Internet port to receive the Ethernet connection .
• Fiber Optic Cable: Typically single-mode or multi-mode with connectors like SC, LC, or ST .
• Ethernet Cable: Cat5e, Cat6, or higher to connect the ONT or media converter to the router .
• Media Converter or SFP/SFP+ Module (optional): Needed if your router has SFP ports or if you are bridging fiber directly to Ethernet .

Step-by-Step Connection

1. Install the ONT
   • Locate the fiber wall outlet where your ISP's fiber line enters your home.
   • Connect the fiber optic cable to the ONT's optical port, handling the connector carefully to avoid dirt or damage .
   • Power on the ONT and wait for the status lights to stabilize (usually 2–5 minutes), .
2. Connect ONT to Router
   • Use an Ethernet cable to link the ONT's LAN/Ethernet port to your router's WAN port .
   • Power on the router and wait for the indicator lights to confirm a successful connection.
3. Alternative: Using a Media Converter or SFP Module
   • If your router supports SFP/SFP+ ports, insert a compatible transceiver module.
   • Connect the fiber optic cable to the SFP module.
   • Use an Ethernet cable from the module to the router's WAN port if needed .
4. Router Configuration
   • Access the router's admin panel via a web browser (commonly 192.168.1.1 or 192.168.0.1).
   • Enter ISP credentials if required.
   • Update firmware and configure Quality of Service (QoS) settings for optimal performance .

Tips for Optimal Performance

• Keep the ONT and router near power outlets and in a dry, ventilated area .
• Use high-quality Ethernet cables (Cat6a or higher) to maintain gigabit speeds .
• Ensure fiber connectors are clean and properly seated to avoid signal degradation .
• Power on the ONT before the router to allow proper network registration . By following these steps, your fiber optic internet connection will be successfully converted to Ethernet and distributed through your router for wired or wireless devices.
