To use Unicom fiber optic internet with a Tenda router, connect the fiber cable to the ONT, then link the ONT to your Tenda router via Ethernet.

Step 1: Prepare Your Equipment

• Optical Network Terminal (ONT): Provided by Unicom, this device converts the fiber optic signal into an electrical signal your router can use .
• Tenda Router: Ensure it supports gigabit speeds and has a WAN or SFP port for Ethernet input .
• Fiber Optic Cable: Usually single-mode with SC/APC or SC/UPC connectors .
• Ethernet Cable: Cat6 or higher is recommended to maintain full fiber speed .

Step 2: Connect the Fiber Cable to the ONT

1. Locate the fiber wall outlet installed by Unicom.
2. Remove protective caps from both the fiber cable and the ONT port.
3. Insert the fiber connector into the ONT's optical port until it clicks securely .
4. Power on the ONT and wait for the status lights to stabilize (typically 2–5 minutes), .

Step 3: Link the ONT to the Tenda Router

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

Step 4: Configure the Router

1. Access the Tenda router's web interface via a browser (usually at 192.168.0.1 or 192.168.1.1).
2. Enter the account credentials provided by Unicom (PPPoE username and password) if required.
3. Enable Quality of Service (QoS) if you plan to prioritize video calls or gaming .
4. Save settings and restart the router if necessary.

Step 5: Test the Connection

• Check that your devices can access the internet.
• Verify speeds using an online speed test to ensure you are getting the expected fiber performance.

Troubleshooting Tips

• Ensure the fiber connector is clean and properly seated in the ONT.
• Confirm the Ethernet cable is fully inserted and undamaged.
• If the router does not detect the internet, check the ONT lights and contact Unicom support for authentication issues . By following these steps, your Tenda router will successfully distribute Unicom fiber optic internet throughout your home or office, providing high-speed, low-latency connectivity.
