PHT 79-411 11 15.8.1980 ABSTRACT: Optical fibre switch. A switch for making and breaking optical connect- ions of optical fibres, by connecting one fibre to a fibre of a group of fibres. The coupling of fibres 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 fibres which are equidistantly distributed over its circumference. A coupling between two fibres 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 fibre on the second holder and a further fibre 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.
