ABSTRACT:
Junction box for a cable comprising optical fibers, consisting of elongate flat holders wherein a splice and the remaining fiber lengths of a pair of fiber ends are stored in each holder. Two elongate plates clamp the holders therebetween. Two end plates are fitted to the end faces of the elongate plates. A housing surrounds the holders and the elongate plates. Each end plate is provided with a feedthrough opening and a pull relief for the optical cable. Each holder has two storage spaces, one for each of the remaining fiber lengths, which are interconnected, via an opening to a sidewall, through a recess. The splice is stored in the recess. Two connecting bolts, which keep the two elongate plates and the holder assembly together and which have a diameter larger than or equal to twice the minimum radius of curvature of the fibers to be coupled, pass through the storage spaces.
