As fiber optic cables are generally only produced in lengths up to around 5 km, so when lengthier connections are needed, splicing two cables together becomes necessary. So in essence, fiber optic splicing is a process used to join two separate fiber optic cables together. There are numerous use cases for fiber optic splicing. As. The time it takes to splice a fiber optic cable can vary depending on several factors, including the type of splice, the equipment used, and the level of expertise of the technician performing the splice. Proper termination is essential for ensuring optimal performance, reducing signal loss, and maintaining the durability of the connection. 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. Fiber optic joints or terminations are made two ways: 1) splices which create a permanent joint between the two fibers or 2) connectors that mate two fibers to create a temporary joint and/or connect the fiber to a piece of network gear. Either joining method must have three primary characteristics.
