Fiber optic splicing is the process of joining two optical fibers end-to-end. Unlike using connectors, which are designed for frequent connection and disconnection at patch panels, splicing creates a permanent, stable joint with minimal light loss. While there's another method of joining fibers known as termination or connectorization, splicing is usually the preferred way to join two fiber optic. The performance of a fiber optic splice is determined by a number of factors, including the quality of the fiber, the cleanliness of the splice, and the techniques used to make the splice.
