The fiber optic router cable has been unplugged

Reconnect the fiber optic cable securely to the router's WAN/Internet port and verify the connection lights to restore network service.

Step 1: Power Check

Ensure both your router and any connected ONT (Optical Network Terminal) or modem are powered on. Check that the power cables are fully plugged in and the power buttons are engaged. Confirm that the outlet is supplying power, for example by testing with a night light or another device .

Step 2: Reconnect the Fiber Cable

Locate the fiber optic cable, typically yellow with green tips, running from the ONT or wall clamshell to your router. Firmly insert the cable into the router's WAN or INTERNET port until it clicks into place. Avoid bending, pinching, or twisting the cable, as fiber optics are sensitive to kinks and damage .

Step 3: Inspect for Damage

Examine the fiber cable for visible damage such as kinks, pinches, or pet bites. If the cable appears damaged, it may need replacement. Also check the connectors and ports for dirt or debris; cleaning with a fiber optic cleaning kit can improve signal quality .

Step 4: Verify Connection Lights

After reconnecting, check the router and ONT lights. A solid green light on the “Power” and “Optical” indicators usually signifies a proper connection. A red or blinking light may indicate a fiber issue, requiring further troubleshooting or a service call .

Step 5: Test Network Functionality

Once the cable is reconnected and lights indicate normal operation, test your internet connection on a computer or mobile device. If the connection is still not working, try restarting the router and ONT, or temporarily using a different Ethernet cable from the ONT to the router to rule out port or cable issues .

Step 6: Seek Professional Assistance if Needed

If the fiber cable is intact, properly connected, and the lights are correct but the internet still does not work, contact your ISP or a service technician. They can test the line, replace faulty components, or dispatch a technician to restore service . Following these steps should restore your network connectivity after a fiber optic cable has been unplugged, while minimizing the risk of damage to the cable or equipment.
