Abstract: The present invention relates to an insert for an optical fiber assembly reliably retaining an optical cable by preventing an axial and rotational movement thereof and further to an optical fiber assembly using such an insert. The insert is provided for guiding a part of the optical cable (12) which comprises at least one optical fiber element (14) and being accommodated in a housing of the optical fiber assembly, wherein said part of the optical cable (12) has a cut-out portion (16) in which a jacket (10) of said optical cable (12) is partially removed, thereby exposing said at least one optical fiber element (14).

Abstract: The present invention relates to an insert for an optical fiber assembly through which an optical fiber element can be pulled out without damage. The insert is provided for guiding a part of the optical cable (2) which comprises at least one optical fiber element (3) and being accommodated in a housing of the optical fiber assembly, wherein said part of the optical cable (2) has a cut-out portion in which a jacket of said optical cable (2) is partially removed, thereby exposing said at least one optical fiber element (3). The insert (1) comprises an optical cable guidance means (4) for guiding said optical cable (2) across the insert (1); a recess (5) surrounding the exposed optical fiber element (3) and a bend element (6) arranged at an end portion of the recess (5) and projecting from the recess (5) in a curved manner.

Abstract: The invention concerns an optical device comprising an optical fiber including at least an integrated component, a support including two fixing zones wherein the optical fiber is fixed respectively at the two zones located on either side of the component. The invention is characterized in that the support comprises, between the two fixing zones, at least a linking beam capable of bending and the device further comprises means for imposing a controlled bending to the beam, adapted to adjust the distance between the two fixing zones.

Abstract: The invention concerns a method for restoring the coating of a previously stripped optical fibre, characterised in that it comprises steps which consist in: applying a drop of viscous substance on one end of the fibre (10) stripped zone, at the interface (22) with the remaining initial coating (20), and shaping said drop into a mass (30) centre on the fibre (10) axis, tapering away from the adjacent initial coating (20), before filling up the fibre stripped space with a mass of substance capable of sheathing said fibre (10) again.

Abstract: The invention concerns an optical device comprising an optical fiber (10) including at least an integrated component, a support (40) including two fixing zones (30, 32) whereon the optical fiber (10) is fixed respectively at the two zones (12, 14) located on either side of the component. The invention is characterized in that the support (40) comprises, between the two fixing zones (30, 32), at least a linking beam (22, 23, 24) capable of bending and the device further comprises means (50) for imposing a controlled bending to the beam (22,23,24), adapted to adjust the distance between the two fixing zones (30, 32).

Abstract: A splice for crimping optical fibers includes two half-cylinders, a support block and a pressing block, which are mutually pressed by a crimping cylinder. The support block is provided with a longitudinal groove for receiving the stripped fiber and bears capped edges. The capped edges and stops are symmetrically mounted on either side of the longitudinal axis of the half-cylinders and are designed for maintaining axis of the half-cylinders and are designed for maintaining a small space between the two half-cylinders in the zone where they are located.

Abstract: The tool is constituted, on one hand, by a lower plate (12) traversed by a calibrated orifice, between an admission chamber (14) equipped with a roller (18) and a cutting plate (15) and, on the other hand, by an upper cover (22) also pierced by an opening (24) emerging in an inlet chamber (26) equipped with a roller (28). The upper cover is placed above the lower plate at distance that is variable so that the calibrated orifice and the opening are aligned, or can be offset heightwise.

Abstract: The device comprises a central spicing body serving to connect in situ two cable end plugs which fit into the splicing body. The central body has lower rails hollowed out therein and bears lateral shoulders for guiding and locking the end plugs constituted by a lower part and by an upper part fixed to one another by a press fit. The device has application in the in situ splicing of optical fibers.

Abstract: To lay an underground cable, a first drum is stationarily positioned and supplies the cable to a trench that is dug in the ground. A hauling pig is connected to the leading end of the cable. A second drum, mounted to a movable tractor, supplies a tube to the trench and is intended to receive the cable. The tractor also has a plowshare mounted to its forward end for forming the trench as the tractor moves. A compressor is connected to a tube section, rearwardly of the pig, for propelling the leading end of the cable to a predetermined point in a turn of a rolled tube as stored on the second drum. In the event an obstacle is encountered by the tractor, the compressor is interrupted and a length of tube, at least as long as one turn on the second roll, is payed out from the second drum and temporarily remains unoccupied by cable. The payed out length of tube is cut at an end so that the tractor becomes free to move around the obstacle.
