The new router does not have an optical fiber cable port

If your router lacks an optical fiber port, you can still use it with fiber internet by connecting it to your ISP-provided ONT via Ethernet.Understanding the SetupFiber internet requires an Optical Network Terminal (ONT), which converts the fiber optic signal into an Ethernet signal that your router can use . The ONT is typically provided and installed by your ISP, and it acts as the interface between the fiber line and your home network.Steps to Connect Your RouterLocate the ONT: This device is usually installed near the fiber wall outlet where the ISP's fiber line enters your home .Connect the ONT to your router: Use a standard Ethernet cable to connect the ONT's Ethernet or LAN port to your router's WAN port .Power on the devices: Ensure both the ONT and your router are powered on and wait for the status lights to stabilize.Configure your router: Access the router's admin panel to enter any ISP credentials, configure VLAN, DHCP, or PPPoE settings if required, and set up Wi-Fi networks .Test the connection: Verify that your internet connection is active and that speeds match your fiber plan.Important ConsiderationsAdapters for direct fiber connection: There is no simple fiber-to-RJ45 adapter that allows a standard router to directly accept a fiber cable. The ONT is necessary because fiber protocols like GPON or XGPON are not compatible with standard Ethernet ports .Router compatibility: Ensure your router has a Gigabit Ethernet WAN port and supports the speeds of your fiber plan. Wi-Fi 6 or 6E routers are recommended for optimal performance .Using your router with the ISP router: If your ISP provides a router integrated with the ONT, you can either use your router in bridge mode or as an access point to extend Wi-Fi coverage . By following these steps, you can use a router without a fiber port while still taking full advantage of your fiber internet connection.
