Xiaomi Router 6 Fiber Optic Interface Location

Xiaomi Router 6 does not have a direct fiber optic port; the fiber connection is made via the WAN Ethernet port through an ONT device.

Fiber Connection Setup

Xiaomi Wi-Fi 6 routers, including the Router 6 series, do not include a native SFP or fiber port. Instead, fiber optic internet is connected through an Optical Network Terminal (ONT) provided by your ISP. The ONT converts the fiber signal into an Ethernet output, which is then plugged into the WAN port on the back of the router .

• The WAN port is usually labeled and often colored differently from LAN ports.
• LAN ports are used for wired connections to computers or switches, while the WAN port receives the internet signal from the ONT.
• After connecting the Ethernet cable from the ONT to the WAN port, the router can be powered on and configured via the Mi Home/Xiaomi Home app or the web interface at 192.168.31.1 .

Additional Notes

• Ensure the ONT is properly set up and activated by your ISP before connecting to the router.
• Some Xiaomi routers support dual WAN or VLAN tagging for fiber services, which may require configuration in the router settings.
• For mesh setups, the main router should be connected to the ONT, and satellite units can be connected via LAN or wirelessly . In summary, the fiber optic interface is effectively the WAN Ethernet port, with the fiber signal first converted by the ONT. Direct fiber plugging into the router is not supported on Xiaomi Router 6 models.
