How to connect fiber optic cable and router inside the wall

You cannot plug a fiber optic cable directly into a standard router; you need an Optical Network Terminal (ONT) to convert the fiber signal to Ethernet, which then connects to your router.Step 1: Identify the Fiber Entry PointLocate where the fiber optic cable enters your home. This is usually a wall outlet or a small termination box installed by your ISP. The fiber cable is typically thin and yellow, with SC/APC or SC/UPC connectors .Step 2: Install the Optical Network Terminal (ONT)The ONT is a device provided by your ISP that converts the light signal from the fiber into electrical signals usable by your router. Connect the fiber cable from the wall outlet to the ONT's optical port, handling the connector carefully to avoid dirt or damage . Power on the ONT and wait for the status lights to stabilize, which may take a few minutes .Step 3: Connect the ONT to Your RouterUse a standard Ethernet cable to link the ONT's LAN or Ethernet output port to the WAN or Internet port on your router. Ensure the router is powered on and positioned near a power outlet in a dry, ventilated area .Step 4: Configure the RouterAccess your router's admin panel via a web browser using its IP address (commonly 192.168.1.1). Enter any ISP-provided credentials if required and update the firmware to ensure optimal performance .Step 5: Optional Wall Plate SetupIf you want a clean installation through the wall, you can use a fiber keystone jack or wall plate. Run a short fiber patch cable from the wall plate to the ONT, and use standard Ethernet cabling for connections to other rooms. Avoid attempting to convert fiber directly to RJ45 without an ONT, as this will degrade signal quality .Step 6: Test the ConnectionConnect a device to the router via Wi-Fi or Ethernet and run a speed test to verify the fiber connection. If there are issues, reboot the ONT and router or contact your ISP for support . By following these steps, you can safely connect a router to a fiber optic cable inside the wall while maintaining high-speed, reliable internet access.
