Fiber core splicing is a commonly used connection technology in the field of optical fiber communications. It is used to fuse the cores of two optical fibers together to ensure low loss and high-quality signal transmission. Here are some basic tips for fiber core splicing:
Preparation: Ensure the work environment is clean and reduces dust and contamination. Use a clean room or similar environment and wear appropriate anti-static and dust-proof equipment.
Choose the right equipment: Use a high-quality fiber optic fusion splicer. A fusion splicer usually includes a microscope, a splicing unit and a core alignment system. Make sure your device's optics and blades are in good condition.
Core alignment: When performing core alignment, ensure that the end face of the fiber is flat and clean. Use a microscope to align the cores and make sure they overlap completely. Care must be taken during the alignment process to ensure that the optical fiber is not damaged.
Strip the outer layer of the optical fiber: Use the optical fiber stripping tool to carefully peel off the outer layer of the optical fiber to expose the fiber core. Make sure not to scratch or stain the fiber core.
Cleaning the fiber core: Using an appropriate cleaning tool, clean the exposed fiber core. This helps ensure that no contaminants get in during the welding process.
Set the parameters of the fusion splicer: According to the type and specifications of the optical fiber, set the splicing parameters of the fusion splicer, such as splicing time, arc power, etc. Different types of optical fibers may require different splicing parameters.
Perform splicing: Place the two optical fibers into the splicing unit, ensuring that the fiber cores are aligned. Start the welding machine and perform core welding. After the welding is completed, the welding machine usually performs automatic cutting and grinding operations.
Check the welding quality: Use a microscope to check the welding points to ensure the quality of the fiber core. Check for gaps, bubbles, or other abnormalities. Make sure the fiber end face quality is good.
Measure loss: Use equipment such as an optical power meter to measure the optical loss at the welding point to ensure good signal transmission performance at the welding point.
Recording and identification: Record the parameters and quality of each welding, and mark the information at the welding point for subsequent maintenance and management.
The above are the basic techniques for general optical fiber core splicing. In actual operation, adjustments need to be made according to specific conditions and equipment requirements.
