How to connect a fiber optic router to a power source

A fiber optic router can be powered using either an AC adapter or a DC power source, following proper wiring and polarity guidelines for safe operation.Connecting to AC PowerMost fiber optic routers come with an AC power adapter. To connect:Locate the AC power input on your router, usually labeled "AC IN."Plug the provided AC adapter into the router and then into a wall outlet.Ensure the outlet is live and the router powers on, indicated by the status lights.Connecting to DC PowerSome routers support DC power as a primary or backup source. To connect a DC power source:Turn off the DC power source at the circuit to ensure safety.Prepare the wires: Strip about 0.25 inches of insulation from both positive and negative wires.Insert wires into the DC connector: Match polarity carefully—positive to positive, negative to negative.Secure the connection: Tighten the terminal screws on the connector to the recommended torque (e.g., 1.243 N-m or 11 lbf-in) to ensure a stable connection.Connect the DC connector to the router and tighten the screws to secure it in place.Power on the DC source and verify the router powers up correctly, indicated by the status lights .Additional TipsAlways check the router's specifications to confirm the supported voltage and current for DC connections.If using both AC and DC, configure the router to use DC as a backup in case AC power fails.Avoid running fiber optic cables near high-voltage lines to prevent interference, although fiber itself is electrically isolated . By following these steps, your fiber optic router will be safely powered and ready for network setup. Once powered, you can connect the fiber optic cable to the router via an ONT or fiber transceiver, then link it to the router's WAN port using an Ethernet cable for full network functionality .
