The simplest method: join two pre-terminated cables via a coupler (also called an adapter). The coupler aligns the two connector ferrules using a zirconia sleeve. This is where fiber optic cable splicing—the process of creating a permanent, high-performance join between two fiber ends—becomes critical. For network managers and technicians, a poor splice can lead to significant signal degradation, network downtime, and costly troubleshooting. There are numerous use cases for fiber optic splicing. The goal is always to minimise this loss — that's what differentiates the three methods. In this guide, we'll explore what splicing of fiber entails, why it's important, and dive into the key methods and tools. There are three standard methods to connect two fiber optic cables: 1.
