Methods for splicing optical fibers in sensing
There are two primary methods of splicing: fusion splicing, which involves melting the glass ends together with heat, and mechanical splicing which involves precise alignments of the fibers for each other and fixing their position with a mechanical device. Splicing is typically required during cable installation, maintenance, or network expansion. The goal is to achieve the lowest possible optical loss (signal. Splicing as a joining procedure is used to build up fiber lasers and for transporting high optical powers in the kW range via optical fibers.
