ABSTRACT:
A switch for making and breaking optical connections of optical fibers, by connecting one fiber to another fiber of a group of fibers. The coupling of fibers is realized in a V-groove in a first holder. The switch comprises two holders, each of which comprises a gear ring. These rings are made to engage by means of a helical spring. The first holder accommodates several fibers which are equidistantly distributed over its circumference. A coupling between two fibers is broken by pulling the holders apart (against the force of the spring). By subsequently rotating the holders and moving the holders towards each other again, a coupling between the fiber on the second holder and a further fiber on the first holder is realized. The second holder comprises a positioning ring which provides coarse orientation of the holders with respect to each other. The two gear rings provide exact final positioning of the holders.
