Simple connection method for broken optical fiber

　　After the fiber is broken, simple connection methods mainly include the following:

　　First, cold connection method

　　Steps:

　　Use a fiber cutter to cut the fiber and ensure that the end face is flat.

　　The PVC layer and coating layer of the optical fiber are stripped to expose the bare fiber.

　　Clean bare fibers to ensure they are free of dust and impurities.

　　The optical fiber is penetrated into the cold connector body and fixed.

　　Use the fiber optic test pen to test the conduction status to ensure that the connection is normal.

　　Advantages and disadvantages:

　　Advantages: Easy to operate, no welding machine required, suitable for field operations or temporary repairs.

　　Disadvantages: Each contact will have a certain signal loss (about 0.2 to 0.5 dB), and the cost may be higher (the cost of a single cold connection is higher than that of a hot melt).

　　Second, the hot melt method

　　Steps:

　　Use a fiber cutter to cut the fiber and ensure that the end face is flat.

　　The PVC layer and coating layer of the optical fiber are stripped to expose the bare fiber.

　　Clean bare fibers to ensure they are free of dust and impurities.

　　The optical fiber is pierced into the heat shrinkable tube and welded using a fusion splicer.

　　After welding, heat the heat shrinkable tube with a heating furnace to shrink it and fix the fiber.

　　Advantages and disadvantages:

　　Advantages: Stable connection quality, low connection loss (about 0.05 to 0.08dB).

　　Disadvantages: Professional welding machines and equipment are required, the cost is high, and the operation is relatively complex.

　　III. Winding method

　　Steps:

　　Directly use a tool (such as a lighter) to burn off the outer skin of the fiber to expose the core.

　　Wrap and tighten the cores corresponding to the colors on both sides.

　　After connecting, wrap it in insulating tape.

　　Advantages and disadvantages:

　　Advantages: Simple and fast operation.

　　Disadvantages: Signal loss and interference are large, and it is only suitable for emergency or temporary detection. It is not suitable for long-term use.

　　Four, wiring method

　　Steps:

　　Connect the 8 cores of the fiber using terminal blocks.

　　Advantages and disadvantages:

　　Advantages: Fast and reliable connection, suitable for large-scale projects.

　　Disadvantages: There are also signal loss issues, and professional wiring tools and skills are required.

　　Precautions

　　During fiber optic connection, ensure that the on-site environment is clean to avoid dust and impurities from entering the fiber end face.

　　When cutting optical fibers, a professional optical fiber cutter should be used to ensure that the end faces are flat.

　　When choosing the connection method, the choice should be based on the actual situation and needs. If the quality and stability of the connection are pursued, and the corresponding equipment and skills are available, the hot melt method can be selected. If quick repair is required in the field or in an emergency, the cold connection method may be more suitable. The winding method and the wiring rule are suitable for temporary repair in specific scenarios.

　　In summary, there are various easy connection methods after the fiber is broken, but each method has its own specific application scenarios and advantages and disadvantages. In actual operation, the appropriate method should be selected according to the specific situation, and the operation should be standardized and accurate. If you do not have the corresponding skills and equipment, it is recommended to seek the help of professional technicians to connect.
