Abstract: In order to spread optical fibers emerging from an end of cable and to firmly attach the cable end with ends of protective jackets in which the spread fibers are strung, the following steps are performed by means a spreading device including mainly a grooved hollow distributor. The distributor is fastened to a sawn off end of a grooved elongated ring in the cable by pinching a central armature emerging from the cable, by jaws housed in the distributor. A split ring is strung around a grooved revolution portion of the distributor. For each fiber, a longitudinal slot of the split ring and a respective groove of the revolution portion are superposed, the end of the jacket of the fiber is entered into the groove through the slot, and the jacket is forced into the groove by partially rotating the split ring so as to superpose the slot and another distributor groove.

Abstract: An optical fiber distributing and connecting equipment is in the form of a box in which first optical fibers fanned-out from first cables are connected to second optical fibers fanned-out from second cables by means of fiber-to-fiber connectors. In order to achieve easy mixing of the second fibers while ensuring that their lengths remain substantially equal, the connectors are laid out in a circular region. This region includes one or more circular, coaxial and possibly stacked slides, on which the connectors are slidably mounted. Ends of the first fibers are inserted in first ends of the connectors located on the outer edge of the slides, and the ends of the second fibers are deployed radially from the central axis of the slides and inserted in the second ends of the connectors located on the inner edge of the slides. A central hole in a disk coaxial with the slides groups together the second fibers close to the central axis of the slides.
