Where to plug the fiber optic network cable into the router

A fiber optic cable connects first to an Optical Network Terminal (ONT), and then the ONT connects to your router via the WAN/Ethernet port.

Step-by-

Step Connection1. Gather the necessary equipment: Fiber optic cable from your ISP, usually with SC/APC or SC/UPC connectors. Optical Network Terminal (ONT), provided by your ISP, which converts the optical signal into an electrical signal.

Router that supports Ethernet input (standard home routers do not accept fiber directly). Ethernet cable (Cat5e or higher) to link the ONT to the router. 2.

Connect the fiber optic cable to the ONT: Locate the fiber wall outlet or Fiber Termination Point installed by your ISP. Carefully insert the fiber optic cable into the ONT's optical port, usually labeled “Fiber” or “GPON.” Handle the connector by its plastic housing to avoid damage, and remove any protective caps. 3.

Connect the ON

T to your router: Use an Ethernet cable to connect the ONT's LAN/Ethernet port to the WAN port on your router.

The WA

N port is often labeled and colored differently from LAN 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 the indicator lights to confirm internet connectivity. 5.

Verify the connection: Check your devices to ensure they can access the internet. The ONT's PON or Optical light should be solid green or blue, indicating an active fiber link.

Important Precautions

Do not bend the fiber cable sharply; it can damage the fiber. Keep connectors clean and free of dust. Ensure both ONT and router are near power outlets and in a dry, ventilated area.

By following these steps, your fiber optic internet will be properly routed through the ONT to your router, ensuring optimal speed and stability.
