Fiber Optic Mechanical Splice

Mechanical splices are most popular for fast, temporary restoration or for splicing multimode fibers in a premises installation. They are also used - without crimping the fibers - as temporary splices for testing bare fibers with OTDRs or OLTSs. Of course most prepolished splice connectors use an internal mechanical splice (several actually have fusion splices) so the mechanisms and techniques described here apply to those also.

The advantage of mechanical splices is they do not need an expensive machine to make the splices. A relatively simple cleaver and some cable preparation tools are all that's needed, although a visual fault locator (VFL) is useful to optimize some types of splices.
