An apparatus for coupling light into and out of optical waveguides to determine the amount of splicing attenuation at a splicing location between a first and second waveguide, characterized by a device for coupling light into the first waveguide and a device for coupling light out of the second waveguide. The device for coupling light into the first waveguide includes an arrangement for holding a portion of the first waveguide in a curved path to form a coupling region, a source of light and an additional optical waveguide for conducting light from the source to the coupling region. The output coupling device includes an arrangement for holding the second waveguide in a curved path, a photodetector for receiving light uncoupled from the second waveguide and an arrangement for measuring the intensity of the light received by the photodetector.

Device for coupling light into an optical waveguide

In an installation for alignment of an optical waveguide, particularly a monomode optical waveguide, for splicing purposes a rotary device grasping the optical waveguide is provided. This rotary device has at least one support plate resting against the optical waveguide which, in relation to the optical waveguide, is displaceably mounted in a tangential direction.

Installation for the alignment of an optical waveguide for splicing

A device for splicing light waveguides, such as optical fibers, having an internal sheath and an outer sheath, characterized by an arrangement for clamping each of the waveguides by engaging their sheaths and lowering the unsheathed end portion into a centering groove where the ends are heated and fused together by an alternating current discharge path. The required convergence and alignment of the light waveguide ends during the welding step are automatically controlled by an advanced arrangement which is sequentially controlled with the welding step. Subsequent to the gearing of the ends, the clamping element releases the waveguides adjacent to the fused joint and are moved by a restoring arrangement to stretch the joint into a straight line position.
