Unplug the fiber optic cable from the China Unicom router

To safely disconnect a fiber optic cable from your China Unicom router, power down the device, identify the connector type, release the locking mechanism, and pull the connector straight out without bending the cable.

Step-by-Step Instructions

1. Power Down the Router Unplug the router from its electrical source to eliminate the risk of exposure to infrared light and protect internal components from damage during disconnection . 2. Prepare Your Workspace Ensure the area around the router is clean and free of dust or debris, as even microscopic particles can damage the fiber tip . 3. Identify the Connector Type Common residential fiber connectors include:

• SC (Subscriber Connector): Rectangular, push-pull design with a plastic tab.
• LC (Lucent Connector): Smaller, uses a clip or latch that must be pressed.
• ST: Twist-and-lock bayonet style.
• FC: Screw-on type. Knowing the connector type helps you release it correctly without applying excessive force . 4. Release the Connector
• For SC connectors, gently depress the plastic tab on top to unlock.
• For LC connectors, squeeze the clip inward toward the connector body.
• For ST connectors, twist counterclockwise to unlock. Avoid pulling on the cable itself; always handle the connector body . 5. Pull the Connector Straight Out Hold the router steady with one hand and pull the connector straight out along its axis. Do not bend, twist, or pull at an angle, as this can damage the fiber or port . 6. Protect the Exposed Fiber End Immediately cover the exposed fiber tip with the supplied dust cap or place it in a clean, protected environment to prevent contamination. Even a small speck of dust can degrade signal quality . 7. Inspect and Test After reconnection or temporary removal, check the fiber and router for proper operation to ensure no damage occurred during disconnection . 8. Seek Professional Help if Needed If the connector is stuck, damaged, or recessed, contact China Unicom support or a certified technician to avoid permanent damage . Following these steps ensures safe handling of your fiber optic cable, protects the router port, and maintains signal integrity.
