You connect a fiber optic cable to a Huawei router via an Optical Network Terminal (ONT), using an Ethernet cable from the ONT to the router's WAN port, then configure the router with your ISP credentials.

Step 1: Prepare Your Equipment

• Fiber optic cable: Usually a thin yellow cable with SC/APC or SC/UPC connectors .
• Optical Network Terminal (ONT): Provided by your ISP; converts the fiber's light signal into an electrical signal your router can use .
• Huawei router: Ensure it has a WAN port or supports fiber input via SFP/PON modules .
• Ethernet cable: Cat6 or higher recommended for optimal speeds .

Step 2: Connect the Fiber Cable to the ONT

1. Locate the fiber wall outlet where your ISP's fiber line enters your home.
2. Remove protective caps from both the fiber cable and the ONT's optical port.
3. Align the connector carefully and insert it into the ONT's optical port until it clicks securely .
4. Power on the ONT and wait 2–5 minutes for the status lights to stabilize .

Step 3: Connect the ONT to the Huawei Router

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

Step 4: Configure the Router

1. Connect a computer or mobile device to the router via Wi-Fi or Ethernet.
2. Open a web browser and enter the router's default IP address (check the label on the router) to access the admin panel .
3. Follow the setup wizard or manually enter your ISP credentials (username, password, VLAN settings if required) to establish the internet connection .
4. Optionally, update the router firmware to ensure optimal performance and security .

Step 5: Verify the Connection

• Check the router's status lights and the ONT's PON/Optical light; solid green or blue indicates a successful connection .
• Test internet access by connecting a device to the router and browsing online.

Tips

• Handle fiber connectors carefully; dirt or damage can degrade signal quality .
• Place the ONT and router in a dry, ventilated area near power outlets.
• If your Huawei router lacks a fiber port, a media converter may be required to bridge the ONT to the router . Following these steps ensures a stable fiber optic connection to your Huawei router, allowing you to fully utilize high-speed internet.
