Connect the router first when bringing fiber optic cable into your home

You should connect the router after the Optical Network Terminal (ONT) is installed and powered, not before.

Installation Sequence

Fiber Line Installation The fiber optic cable is first run from your provider's network to your home, either overhead or underground, and connected to a Network Interface Device (NID) outside your home. Optical Network Terminal (ONT) Setup The ONT is installed inside or near your electrical panel. It converts the incoming light signals from the fiber into electrical signals that your router can use.

The fiber cable from the wall outlet is plugged into the ONT, which is then powered on and allowed to stabilize for a few minutes.

Router Connection Once the ON

T is active, connect it to your router using a high-quality Ethernet cable (CAT6 or better). The Ethernet cable runs from the ONT's LAN port to the router's WAN port. After connecting, power on the router and configure Wi-Fi settings as needed.

Testing and Optimization The technician or homeowner should verify the connection speed, Wi-Fi coverage, and device connectivity. For optimal performance, place the router centrally in your home and ensure firmware is up to date.

Key Points

Do not connect the router before the ONT: The ONT must first convert the fiber signal into a usable electrical signal. Connecting the router first will prevent the network from functioning properly. Use proper cables: Fiber-to-ONT connections require specialized fiber cables, while the ONT-to-router link uses Ethernet.

Optional combo units: Some providers supply a single device combining ONT and router functions, in which case the sequence is simplified. Following this sequence ensures a stable, high-speed fiber connection and avoids common setup issues.
