How to plug in the single-mode dual-core fiber jumper cable?

　　The plugging steps of a single-mode dual-core fiber jumper mainly depend on the fiber interface type of the device and the interface type of the fiber jumper. The following is a general plugging step:

　　I. Preparation

　　Confirm the interface type: First, you need to confirm whether the fiber optic interface type of the device matches the interface type of the fiber optic jumper. Common fiber optic interface types include FC, SC, LC, ST, etc.

　　Clean the interface: Use a dedicated fiber optic cleaning tool or alcohol wipe to clean the connector of the fiber optic interface and fiber optic jumper to ensure that there is no dust or stains.

　　Two, plug step

　　Open the device interface: If the fiber optic interface of the device has a dust cover or protective cover, it needs to be opened or removed first.

　　Alignment interface: Align the connector of the fiber optic jumper to the fiber optic interface of the device to ensure the correct orientation of the interface.

　　Gently insert: Gently insert the connector of the fiber optic jumper into the fiber optic connector of the device until you hear a "click" or feel that the connector is clamped.

　　Check the connection: Gently pull the fiber optic jumper cable to ensure that the connector is firmly attached to the fiber optic interface of the device and does not come loose or fall off.

　　III. Precautions

　　Avoid brute force: When plugging in fiber optic jumpers, avoid using brute force or excessive force to avoid damaging the fiber optic interface or connector.

　　Attention to direction: Different fiber optic interface types have different plug-in directions. It is necessary to ensure that the plug-in direction is correct, otherwise the interface may be damaged or unable to connect.

　　Keep it clean: During the plugging process, keep the fiber optic interface and connector clean to avoid dust or stains from entering the interface.

　　IV. Special circumstances

　　If the fiber optic interface of the device is blind: that is, there is no clear insertion direction, you can determine the insertion direction by observing the shape or color of the interface, or refer to the device's manual.

　　If the connector of the fiber optic jumper does not match the fiber optic interface of the device: you can use an adapter or adapter to connect the two. Adapters or adapters usually have two different types of interfaces, which can be connected to the connector of the fiber optic jumper and the fiber optic interface of the device respectively.

　　In short, when plugging in single-mode dual-core fiber optic jumpers, it is necessary to carefully confirm the interface type, clean the interface, plug correctly, and check whether the connection is firm. If you encounter special circumstances, you can refer to the equipment manual or consult a professional technician.
