You cannot plug a fiber optic cable directly into a standard router; it must first connect to an Optical Network Terminal (ONT), which then links to your router via Ethernet.

Step 1: Gather Your Equipment

• Fiber optic cable: Usually thin, yellow, with SC/APC or SC/UPC connectors. Handle carefully to avoid dirt or damage .
• Optical Network Terminal (ONT): Converts the fiber's light signals into electrical signals your router can use .
• Router: Ensure it has a WAN or Internet port compatible with Ethernet input.
• Ethernet cable: Typically Cat6 or higher for optimal speed.
• Power adapters: For both the ONT and router.

Step 2: Connect the Fiber to the ONT

1. Locate the fiber wall outlet where your ISP's line enters your home.
2. Remove protective caps from both the fiber cable and the ONT's optical port.
3. Align the fiber connector with the ONT port using the key/tab on the connector.
4. Push gently until it clicks into place, ensuring a secure connection .

Step 3: Power the ONT

• Plug in the ONT using its power adapter (often a two-prong plug).
• Wait 2–5 minutes for the status lights to stabilize, indicating the ONT is ready .

Step 4: Connect the ONT to Your Router

1. Use an Ethernet cable to connect the ONT's LAN/Ethernet port to the router's WAN/Internet port .
2. Power on the router and wait for the indicator lights to confirm a successful connection.

Step 5: Verify and Configure

• Check that the Power and Internet lights on both devices are solid green.
• Access your router's settings via a web browser if manual configuration is required by your ISP .

Tips for Safe Handling

• Avoid bending or twisting the fiber cable sharply.
• Keep connectors clean; dust or fingerprints can degrade signal quality.
• Place both ONT and router in a dry, ventilated area near electrical outlets . Following these steps ensures a stable, high-speed fiber connection from your ISP to your home network.
