Where should the fiber optic cable be plugged into the router

The fiber optic cable from your ISP should be plugged into the Optical Network Terminal (ONT), which then connects to your router via the WAN/Ethernet port.Step-by-Step Connection1. Identify the ONT: Most fiber internet setups require an Optical Network Terminal (ONT), provided by your ISP. The ONT converts the incoming light signals from the fiber into electrical signals that your router can use . 2. Connect the Fiber Cable to the ONT:Locate the fiber optic wall outlet where the ISP's line enters your home.Remove any protective caps from both the fiber cable and the ONT's optical port.Carefully insert the fiber cable into the ONT's designated optical port until it clicks securely . Handle the cable by its plastic housing to avoid damage. 3. Link the ONT to Your Router:Use a standard Ethernet cable to connect the ONT's LAN/Ethernet output port to the WAN (Internet) port on your router. This port is usually labeled “WAN” or “Internet” and may be colored differently from other Ethernet ports . 4. Power On the Devices:First, plug in and power on the ONT. Wait for the status lights to stabilize, indicating a successful connection to the ISP network.Next, power on your router and wait for its indicator lights to confirm internet connectivity .Important TipsRouter Compatibility: Ensure your router supports fiber connections or has a compatible SFP/fiber port if connecting directly. Most home routers use Ethernet from the ONT .Cable Handling: Avoid bending the fiber cable sharply and keep connectors clean to prevent signal loss .Placement: Position both the ONT and router near power outlets in a dry, ventilated area, ideally protected by a surge suppressor . By following this setup, your fiber optic internet will be properly routed through the ONT to your router, ensuring optimal speed and stability.
