Xiaomi routers like the Be5000 and Mi Router 4A Gigabit Edition are compatible with fiber optic internet, typically connecting via an ONT using an Ethernet cable.

Required Equipment

To connect fiber optic internet to a Xiaomi router, you will need:

• Optical Network Terminal (ONT): Provided by your ISP, it converts the fiber optic light signal into an electrical signal compatible with routers .
• Fiber optic cable: Connects the wall outlet to the ONT, usually with SC/APC or SC/UPC connectors .
• Ethernet cable: Links the ONT to the router's WAN port .
• Xiaomi router: Ensure your model supports fiber connections. The Be5000 has a dedicated 2.5Gbps WAN port, while the Mi Router 4A Gigabit Edition supports full-gigabit fiber via its WAN port .

Step-by-Step Connection

1. Install the ONT:
   • Locate the fiber wall outlet.
   • Connect the fiber optic cable from the wall to the ONT's optical port. Handle the connectors carefully to avoid dirt or damage .
   • Power on the ONT and wait for the status lights to stabilize.
2. Connect the ONT to the Xiaomi Router:
   • Use an Ethernet cable to connect the ONT's LAN/Ethernet port to the router's WAN port. For the Be5000, use the 2.5Gbps WAN port to fully utilize high-speed fiber .
   • Power on the router and wait for the indicator lights to confirm a successful connection.
3. Router Configuration:
   • Access the router's web interface (usually 192.168.31.1 for Xiaomi routers).
   • Configure your internet settings as required by your ISP. Enable features like Quality of Service (QoS) if needed for streaming or gaming .

Additional Tips

• Place both the ONT and router near power outlets and in a dry, ventilated area .
• The Be5000 can handle multi-gigabit fiber plans without additional media converters, while older models like the Mi Router 4A may be limited to 1Gbps speeds .
• For large homes, consider Xiaomi mesh systems or routers with multiple LAN ports to extend coverage and maintain high speeds. By following these steps, your Xiaomi router will efficiently handle fiber optic internet, providing high-speed, low-latency connectivity for wired and wireless devices.
