Splices create a permanent joint between two fibers, so its use is limited to places where cables are not expected to be available for servicing in the future. The most common application for splicing is concatenating (joining) cables in long outside plant cable runs where the length of the run requires more than one cable. Splicing can be used to mix a number of different types of cables such as connecting a 48 fiber cable to six 8 fiber cables going to various locations. Splicing is generally used to terminate singlemode fibers by splicing preterminated pigtails onto each fiber. And of course, splicing is used for OSP restoration.

Splicing is more common in outside plant (OSP) applications than premises cabling, where most cables are pulled in one piece and directly terminated. Splicing is only needed if the cable runs are too long for one straight pull or you need to mix a number of different types of cables (like bringing a 48 fiber cable in and splicing it to six 8 fiber cables.) And of course, we often use splices for OSP restoration, after the number one problem of outside plant cables, a dig-up and cut of a buried cable, usually referred to as "backhoe fade" for obvious reasons!

There are two types of splices, fusion and mechanical. Fusion splicing is most widely used as it provides for the lowest loss and least reflectance, as well as providing the strongest and most reliable joint. Fusion splicing machines are available in two types that splice a single fiber or a ribbon of 12 fibers at one time. Virtually all singlemode splices are fusion. Mechanical splicing is mostly used for temporary restoration and for multimode splicing. In the photo below, a fusion splice is on the left and the rest are various types of mechanical splices.
