Fiber splicing is the process of joining two optical fibers together to create a continuous path for light transmission. This technique is essential in telecommunications and data networks, as it helps maintain signal strength and quality over long distances. There are two main methods of splicing: fusion splicing, which uses heat to melt the fibers together, and mechanical splicing, which aligns the fibers and holds them in place with a special adhesive. Proper fiber splicing requires precision and specialized tools to ensure minimal signal loss. Technicians often use a fiber optic splicer to perform the task, which can measure and align the fibers accurately. Successful splicing is crucial for the reliability of fiber optic networks, which are widely used for internet and communication services.
