DEVICE FOR COUPLING TWO OPTICAL FIBRES

摘要

PHF 79-579 15.10.1980 Device for coupling two optical fibres. The coupling device in accordance with the invention comprises two coupling members, each of which comprises a circular-cylindrical recess on one side. An end of a fibre to be coupled is centred in the recess by means of two sets of balls which are arranged one on top of the other. The first set of balls bears against the fibre end. The second set of balls bears on the first set and against the wall of the recess and presses the first set of balls against the fibre end. A spherical lens is arranged on the second set of balls so that the optical axis of the lens coincides with the axis of the centred fibre. Application: optical (tele) communication.
