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. This approach maintains network performance while allowing flexible reconfiguration. The goal is clean.
