Fiber optic splicing involves joining two fiber optic cables to create a continuous optical path. For network managers and technicians, a poor splice can lead to significant signal degradation, network downtime, and costly troubleshooting. 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. As fiber optic connections become increasingly mainstream, the need to connect fiber optic cables to one another — or splicing — is also on the rise. In this guide, we'll explore what splicing of fiber entails, why it's important, and dive into the key methods and tools.
