Which port should the fiber optic cable be plugged into when changing the router

You should plug the fiber optic cable into the Optical Network Terminal (ONT) provided by your ISP, then connect the ONT to your router's WAN port using an Ethernet cable.

Step-by-

Step Guide1. Connect the Fiber Cable to the ONT Fiber optic cables carry light signals, which standard routers cannot interpret.

Your IS

P provides an Optical Network Terminal (ONT) that converts the fiber signal into an electrical Ethernet signal. Plug the fiber optic cable from your ISP into the designated port on the ONT, usually labeled and protected by a dust cap. Handle the connector carefully to avoid damage or dirt contamination.

2.

Link the ON

T to Your Router Use a high-quality Ethernet cable (Cat6 or Cat6a recommended) to connect the ONT's Ethernet output port to your router's WAN (Wide Area Network) port.

The WA

N port is often colored differently and clearly labeled, as it is designed to receive the external internet feed. 3.

Power On and Configure Devices

First, power on the ONT and wait for its status lights to stabilize, indicating a successful connection to your ISP. Next, power on your router. Access the router's admin panel (commonly via 192.

168. 1. 1 or 192.

168. 0. 1) and configure the WAN settings according to your ISP's instructions, which may involve setting the connection type to Dynamic IP or PPPoE.

4. Test Your Connection Once everything is connected and configured, check for internet access on a device connected to your router. Running a speed test can confirm that your fiber connection is functioning at expected speeds.

Key Points to Remember

Do not plug the fiber cable directly into the router unless it has a dedicated SFP or fiber port.

The ON

T is essential for converting the optical signal to Ethernet. Always use a high-quality Ethernet cable to maintain the full speed of your fiber connection. Following this setup ensures your fiber optic internet is properly routed through your home network.
