To connect a router to a fiber optic port, you need an Optical Network Terminal (ONT) to convert the fiber signal, then link it to your router via an Ethernet cable.

Required Equipment

• Optical Network Terminal (ONT): Converts the incoming fiber optic light signal into an electrical signal your router can use, usually provided by your ISP .
• Fiber optic cable: Typically single-mode with SC/APC or SC/UPC connectors .
• Router: Ensure it supports fiber connections, either via a WAN port or SFP slot .
• Ethernet cable (Cat6a or higher): Connects the ONT to the router to maintain high-speed performance .

Step-by-Step Connection

1. Install the ONT
   • Locate the fiber optic wall outlet where your ISP's fiber line enters your home.
   • Connect the fiber optic cable from the wall outlet 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 the ONT to the Router
   • Use an Ethernet cable to connect the ONT's LAN/Ethernet port to your router's WAN or Internet port .
   • Power on the router and wait for the indicator lights to confirm a successful connection .
3. Router Placement and Configuration
   • Place the router in a central, well-ventilated location near a power outlet for optimal Wi-Fi coverage .
   • Access the router's settings via its IP address to configure WAN type, DHCP, or other ISP-specific settings if required .
   • Ensure the router firmware is up to date to maintain compatibility and performance .

Tips for Optimal Performance

• Keep the ONT and router away from moisture, heat, or direct sunlight .
• Avoid bending the fiber optic cable sharply to prevent signal loss .
• If your router lacks a fiber port, a media converter may be needed to bridge the fiber signal to Ethernet . Following these steps ensures a stable, high-speed fiber internet connection from the wall outlet to your router, ready for wired or wireless devices.
