Precisely insert two fiber ends into the fiber optic mechanical splice so that two fiber ends can maintain contact with each other with the index matching gel inside. Before jumping into the physical steps, it's important to understand the two primary methods of fiber splicing: fusion splicing and mechanical splicing. What is Fiber Optic Splicing and Why is it Needed? – #1. Use and Maintain Your. In this video, we'll guide you through preparing and terminating fiber optic cables using SimplyFiber products, known for their high quality, ease of use, and reliability. more Audio tracks for some languages were automatically generated. Another method of connecting optical fibers is termination or connectorization, which consists of processing the end of a fiber optic bundle so that it can be connected to other fibers or devices through fiber optic. The incoming optical fiber or indoor optical fiber can be inserted into the mechanical splicing mechanism without using other tools, and the termination process only takes about 2 minutes, which greatly saves installation time.
