Abstract: A light waveguide signal detector enables testing for the transmission of a signal in a light waveguide without disturbing the transmission of the signal. The light waveguide signal detector comprises a base part having a pressure trough lined with an optically transparent material, at least one light receiver being arranged under the elastic material, a pressure part for deflecting the light waveguide to obtain an emergence of a light signal therefrom and a light covering for protecting against stray light surrounding a portion of the pressure part which engages the optical fiber.

Abstract: A cassette which serves the purpose of connecting and branching light waveguides has a reserve length thereof for each of the waveguides deposited in the cassette in either a figure eight or circular or oval pattern. To accomplish this, the cassette is formed with upstanding holding devices which enable winding the waveguides in a figure eight pattern or in a circular pattern, or both. A plurality of the cassettes can be interconnected together to form a cassette block which can be opened hinge-like. To interconnect waveguides in one cassette with the other cassette, each of the cassettes is provided with an opening in a floor of the cassette and a portion of the side wall midway along the longitudinal side wall, which side wall is positioned adjacent a hinge interconnecting the cassettes together.

Abstract: The crimp splice serves the purpose of connecting light waveguide fibers which are fixed by radial pressure. For this purpose, the light waveguide fibers are placed in a guide channel in the base surface or area of, for example, an outer part, are pressed against one another, and are fixed by a clamping action between an inner part and the outer part. A required pressing power for the clamping is achieved by pressing legs of the two parts together. The crimp splice is simple to produce and permits easy assembly.

Abstract: A division rack comprises one or more distributor housings, with each distributor housing having a cassette holder mounted for pivotable movement between a first position received in the housing and a second position extending horizontally out of the housing. Each cassette holder comprises a channel-shaped member having a plurality of guide webs forming compartments for receiving cassettes or cassette blocks, which guide webs extend obliquely relative to the axis of the holder so that the cassettes are stored in an oblique position when the holder is in its first, vertical position. The incoming cables to each of the cassettes are clamped in the housing and extend over an upper end of each of the holders to the individual cassettes or cassette blocks.

Abstract: A cassette for storing spare lengths of light waveguides with their splices is designed as a rotary splice cassette which includes a rotatable cover part. A splice holder that can hold a number of splices is attached to this cover part.

Abstract: A splicing device comprises a bottom part with a V-notch and a cover part to be fixed thereon, the two parts being held together by a metal sleeve. The necessary pressing force for satisfactory fixing of the light waveguides to be joined in the V-notch is brought about by a permanent plastic deformation of the metal sleeve in the region of cutouts in the bottom and cover parts.

Abstract: A compact configuration of a large number of splicing modules that enables each splicing module to be freely accessible is made by connecting each splicing module to a carrier with a pivotal connection so that the pivoting axis extends through the interior of the splicing module, parallel to the direction in which the light waveguide bundle is introduced into the splicing module. The pivoting axes of several splicing modules extend parallel to one another. Each splicing module has a hollow cylinder that is mounted to the carrier with U-sections. Light waveguides are led through the hollow cylinders to each splicing module. No excess length of the light waveguides is necessary since the hollow cylinders remain stationary during pivoting of a splicing module. The pivotal connection of the splicing modules enables them to be "leafed through" like a book. Each splicing module can be accessed in this manner so that the light waveguide splices located on it can be renewed or repaired.

Abstract: A receptacle for supporting at least one light waveguide connector characterized by the receptacle having a plate-shaped member having grasping jaws for grasping only one end region of the connector so that each connector is grasped only at a single end region. Preferably, the plate member is provided with depressions adjacent the free end of each connector so that the connector can be removed from the jaws by pushing on the free end to pivot the connector to pop the grasped end from the jaws.

Abstract: A connector device for two light waveguides, which has a receptacle part formed by a carrier member having a recess receiving a central retaining part, which is movable in a radial direction in the recess, and a pair of pressure members movable from a position to urge the central retaining part radially inward to clamp stripped waveguides in an abutting alignment. The pressing members are constructed so that when in a non-pressing position, they still maintain the central retaining part in a loose, assembled relationship. The device can also include a gripping arrangement at each end for gripping the unstripped portions of the waveguide so that the joint between the two stripped portions is not subjected to tension placed on the waveguides.

Abstract: A connector element, which is composed of two carrier members with cover plates that are held in alignment by guide rails received in guide channels of the member, is provided with an arrangement of collecting surfaces for collecting excess adhesive materials and immersion fluids to keep these fluids and materials from the guide channels of the carrier members. The collecting surfaces can be formed by parting webs, by grooves in the carrier members, or beveled edge surfaces of the cover plates of each carrier member.

Abstract: A connector device for interconnecting a plurality of light waveguides comprises two carrier members which have aligning centering grooves for receiving waveguides which are stripped of the cladding. Each of the carrier members has a recess adjacent a rear end in which the unstripped portions of the waveguides are accepted. A first adhesive, which hardens as a very hard adhesive, is utilized for securing the waveguides in the centering grooves adjacent the first surface which will be ground to form the abutting surface and a second adhesive which is substantially softer and more elastic in the hardened condition is utilized for securing the cladded portions of the waveguide in the recess so that less stress is applied to the waveguides.

Abstract: A connector element for light waveguides has two carrier members which have guide grooves for the optical fibers and guide channels receiving guide ribs of guide rails for holding the two carrier members in alignment. To prevent possible misalignment due to micro-offsets in the surfaces of the guide channels and ribs of the guide rails or dust particles or the penetration of an immersion material into the guide channel, a portion of the contacting surfaces, either the contacting surface of the guide channel or of the guide rib is removed so that engagement between the rib and channel occurs only at spaced locations.

Abstract: A connector device for a plurality of light waveguides comprises two carrier members having centering grooves which are aligned together by means of a guide elements received in guide grooves and bridging the two carrier members. In order to maintain pressure between the guide elements and guide grooves, a spring clip is provided for applying a holding force in this location without applying a force on the carrier member adjacent the centering grooves.
