Should the network cable be plugged into the router or the fiber optic cable
The fiber optic cable should connect to an Optical Network Terminal (ONT), and then an Ethernet cable from the ONT should be plugged into your router's WAN port.
Why You Don't Plug Fiber Directly into a Router
Fiber optic cables transmit data as light pulses, while standard home routers use electrical signals over Ethernet (RJ45) connections. Because of this difference, a direct connection from fiber to a typical router is not possible . The ONT acts as a converter, translating the optical signals from the fiber into electrical signals that your router can understand .
Correct Connection Sequence
- Fiber Cable to ONT: Plug the fiber optic cable from your wall outlet into the ONT's optical port. Handle the fiber connector carefully to avoid dirt or damage .
- ONT to Router: Use a high-quality Ethernet cable (Cat6 or better) to connect the ONT's Ethernet/LAN port to the WAN port on your router .
- Power and Configure: Power on the ONT first, wait for the status lights to stabilize, then power on the router. Access the router's admin panel to configure settings if required .
- Test the Connection: Connect a device via Wi-Fi or Ethernet and run a speed test to ensure the fiber connection is functioning properly .
Optional Configurations
- Some ISPs provide a combo device that integrates the ONT and router in one unit, eliminating the need for a separate Ethernet connection .
- For larger homes, mesh Wi-Fi systems can be added to extend coverage while still connecting to the ONT via the main router . By following this setup, you ensure that your fiber internet delivers high-speed, low-latency connectivity throughout your home or office .
