Reconnect your fiber optic cable by linking it to the Optical Network Terminal (ONT) first, then connecting the ONT to your router via Ethernet.

Step 1: Gather Necessary Equipment

Ensure you have the following:

• Fiber optic cable from your ISP, usually with SC/APC or SC/UPC connectors.
• Optical Network Terminal (ONT), provided by your ISP, which converts optical signals to electrical signals.
• Ethernet cable (Cat6 or higher) to connect the ONT to your router.
• Router with a WAN or Internet port compatible with Ethernet input .

Step 2: Connect the Fiber Cable to the ONT

1. Locate the fiber port on the ONT.
2. Remove any protective caps from both the fiber cable and the ONT port.
3. Handle the fiber connector by its plastic housing to avoid contamination or damage.
4. Align the connector with the port's key or tab and gently push until it clicks securely .
5. Ensure the connection is firm, as improper seating can degrade signal quality significantly .

Step 3: Connect the ONT to Your Router

1. Use an Ethernet cable to link the LAN or Ethernet output port on the ONT to the WAN/Internet port on your router.
2. Make sure the Ethernet cable is fully inserted and the ports are correctly matched .
3. Position both devices near a power source and in a dry, ventilated area.

Step 4: Power On and Verify

1. Plug in the ONT and wait for it to boot and register with your ISP's network. Status lights should indicate power and active optical connection (solid green or blue).
2. Power on your router and wait for the indicator lights to confirm a successful connection.
3. Access your router's configuration interface via a web browser (commonly 192.168.0.1 or 192.168.1.1) to verify settings and configure Wi-Fi if needed .

Step 5: Troubleshooting

• If the connection fails, check that the fiber connector is clean and properly seated.
• Ensure the Ethernet cable is functional and connected to the correct ports.
• Confirm the ONT has power and the optical link is active.
• For persistent issues, contact your ISP for ONT registration or signal verification . By following these steps carefully, you can safely and effectively reconnect your fiber optic cable to your router, ensuring optimal internet performance and stability.
