Where should the router s fiber optic cable be plugged in

A fiber optic cable from your ISP should be plugged into an Optical Network Terminal (ONT), which then connects to your router via the WAN/Ethernet port.Connecting Fiber to Your Home NetworkFiber optic cables cannot be plugged directly into a standard home router because the optical signal must first be converted into an electrical signal. This conversion is handled by an Optical Network Terminal (ONT), typically provided and installed by your internet service provider (ISP) near the point where the fiber enters your home .Steps to ConnectLocate the ONT: The ONT is usually mounted on an interior wall or in a closet near the fiber entry point. It has an optical port for the fiber cable and one or more Ethernet ports for connecting networking devices .Connect the Fiber Cable: Remove the protective caps from both the fiber cable and the ONT port. Align the connector carefully and insert it until it clicks securely. Handle the fiber by its plastic housing to avoid damage .Link the ONT to the Router: Use a standard Ethernet cable to connect the ONT's LAN or Ethernet output port to the WAN/Internet port on your router. The WAN port is often labeled and may be colored differently from other ports .Power Up Devices: First, plug in the ONT and wait for it to establish a connection with your ISP. Once the ONT is stable, power on your router. Check the status lights on both devices to confirm a successful connection .Additional TipsEnsure both the ONT and router are near a power outlet and in a dry, ventilated area.Avoid bending the fiber cable sharply, as this can damage the delicate strands.If your router has a dedicated fiber port (SFP or PON), it may allow direct fiber connection, but most home setups still require an ONT . By following these steps, your fiber optic internet will be properly routed through the ONT to your router, providing stable and high-speed connectivity throughout your home.
