This application note describes fundamental theory and applications behind optical fiber splicing for mechanical and, in particular, fusion spliced joints. Various fiber preparation, alignment, splicing and testing methods are discussed, as well as safety. Fusion splicing is the process of fusing or welding two fibers together usually by an electric arc. Fusion splicing is the most widely used method of splicing as it provides for the lowest loss and least reflectance, as well as providing the strongest and most reliable joint between two fibers. That is usually done for permanent connections, but it may be possible to dismantle a splice without spoiling the fiber ends. Another technique is fusion splicing, where the fibers are fused. In the complex world of fiber optic networking, two giants dominate: Single-Mode Fiber (SMF) and Multi-Mode Fiber (MMF). The guide provides the complete workflow, covering safety precautions, tool selection, fiber preparation, fusion operation, quality control, and. Here's a step-by-step guide to achieving a perfect fusion splice: Prepare the Cables: Begin by stripping the cable jacket to expose approximately 2-3 meters of buffer tubes and fibers needed for splicing. Automatic Mode (Auto Mode) Auto Mode is the most intuitive and user-friendly splice mode.
