Fusion splicing is a method used to join two optical fibers together. This process involves aligning the fibers precisely and then using heat to melt their ends, allowing them to fuse into a single continuous fiber. This technique is essential for maintaining the integrity and performance of fiber optic networks. The advantages of fusion splicing include low signal loss and high strength at the splice point. It is commonly used in telecommunications and data transmission, where reliable connections are crucial. Properly executed fusion splicing can significantly enhance the efficiency of communication systems.
