A router should not be placed inside a fiber optic box; it should connect to the ONT via Ethernet, ideally in an open, central location for optimal Wi-Fi coverage.

Technical Considerations

Fiber optic boxes, or ONTs (Optical Network Terminals), are designed to terminate the fiber connection and convert it to Ethernet for your router. Routers are not designed to fit inside these boxes, and placing one inside could block ventilation, interfere with signal strength, and make maintenance difficult . The ONT itself is usually a small box mounted on an interior wall, with a power supply and a fiber input, and it provides an Ethernet output for the router .

Recommended Setup

• Connection via Ethernet: The router should connect to the ONT using a Cat5e or better Ethernet cable. This cable can run up to 100 meters without significant speed loss, allowing flexibility in router placement .
• Optimal Wi-Fi Placement: For best wireless performance, place the router in a central, elevated, and open location away from metal objects, mirrors, and other electronics that can interfere with the signal . Avoid placing it in cupboards, behind doors, or near appliances like microwaves or refrigerators.
• Power Access: Ensure the router is near a power outlet or use an extension lead if needed. The ONT itself also requires a nearby power source .

Alternatives

If the ONT is far from the ideal router location, you can run a long Ethernet cable from the ONT to the router. This allows the router to be positioned for maximum Wi-Fi coverage while maintaining a wired connection for speed and stability . In cases where multiple devices need Ethernet connections, a small unmanaged switch can expand the number of ports without affecting performance .

Summary

Placing a router inside a fiber optic box is not recommended. Instead, connect the router to the ONT via Ethernet and position it in a central, open area for optimal Wi-Fi coverage. This setup ensures both safety and performance while allowing easy access for troubleshooting or upgrades.
