crimp splice

The crimp splice is a mechanical connection of two optical fibers. It is also called mechanical splice or NENP splice, no-epoxy no-polish (NENP), and is mainly used for repair work on optical fibers, as it is faster and cheaper to produce than the adhesive splice and the fusion splice.

Crimp splicing is a mechanical splice that can be used to splice multimode fibers and monomode fibers with a crimp splicer. The preparation for crimp splicing is done in the same way as for fusion splicing: the fibers are stripped to a specific length, cleaned and broken. Alignment of the fibers takes place in a V-shaped aluminum part, into which the two fibers are inserted and pushed together with their end faces. The end-face coupling is assisted by an index-matching gel, which provides a good match between the different refractive indices of the optical fibers. The optical fibers are then pressed into the aluminum part using a special crimping tool. Since both the alignment of the fibers and the contacting are not comparable with those of a fusion splice, the attenuation values of the splice are also correspondingly higher. These are around 0.3 dB.
