Fiber optic splicing is often the preferred way to connect two fiber optic cables because it has lower light loss (attenuation) and back reflection than connectorization. Fusion splicing and mechanical splicing are the two most common methods of fiber optic splicing. AOCsarrive. This document describes the specifications for preparing, routing, and bundling cables and attaching labels to these cables. 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. In the rapidly evolving fields of telecommunications, medical imaging, and industrial sensing, fiber optic bundles serve as the cornerstone for efficient and reliable data transmission.
