Abstract: A method of forming a joint in an optical line that extends along a phase conductor (1) of a high voltage overhead power transmission system, comprises: (i) forming a length of optical cable (10) which comprises a plurality of optical fibres; (ii) encapsulating the optical fibres; (iii) providing an intermediate region of the length of optical cable with an outer, non-tracking jacket (12) so that a part of the length of optical cable extends from each end of the outer, non-tracking jacket; (iv) installing the jacket so that it extends between phase potential and any other potential to which the cable will be subjected; and (v) connecting one end of the optical fibres of the optical cable to fibres in the optical line of the phase conductor (1), and connecting the other end of the optical fibres of the optical cable to another optical line. The parts of the length of the optical cable that extend from each end of the outer, non-tracking jacket (12) have a sufficient length that connections can be formed between the optical fibres and the optical lines at points remote from regions in which the cable extends along high electrical field gradients. This has the advantage that the optical fibres of the assembly which, in use, will extend between the potential of the phase conductor and earth can be encapsulated in the factory under controlled conditions, and conventional means may be employed to connect the cable.

Abstract: A system and method to breakout and splice into optical circuits in a ribbon cable trunkline extending throughout an aircraft with optical minimal loss. Breakout boxes are positioned at strategic locations along the aircraft's fiber optic trunkline. Within each box, optical fibers in a loose bundle are permanently connected in ribbon cable form to the inner sides of cable connectors physically connected to the box, each extending through a wall of the box. The ribbon cable forms are transitioned into the fibers in the bundle, which are longer than the spacing between the cable connectors. When an optical fiber circuit needs to be broken out at the location of a particular box, the proper fiber in the bundle is cut and one or both ends that result are permanently connected to a breakout connector, also positionned through the box, so that the optical circuit appears on the breakout connector outside the box where a mating connector can be used to further route the optical circuit being broken out.

Abstract: The invention relates to a device for splicing one or more optical-fibre cables (1, 1'). When splicing optical fibres (2, 2'), for instance welding the fibres, it will preferably be possible to store fibre slack at the location of the splices without subjecting the optical fibres to mechanical forces. The inventive device includes a generally cylindrical body (4) having one or more grooves (8) disposed around the periphery of the cylindrical body. The grooves are adapted to accommodate one or more sleeves (6) that enclose an optical-fibre splice. The cylindrical body has at each end at least one recess for fastening the tension-relieving core (3) of the optical cables by means of a screw (5). The smallest permitted bending radius of the optical fibres determines the curved shape of the cylindrical body. The cylindrical body and the spliced optical fibres are enclosed by an outer casing (9). The invention also relates to a method of splicing optical-fibre cables.

Abstract: An optical fiber entry strain relief interface includes a composite structure (lay-up) (10) having an optical fiber (20) embedded therein. The optical fiber (20) enters (or exits) the lay-up (10) at at least one point (24) and passes through transition layers (47) comprising an adhesive film (42), a thin rubber sealing layer (44), and a thick rubber strain relief layer (46), and through a polymer plug (48) located above the layer (46). The lay-up is consolidated by heating the lay-up over a temperature profile and applying pressure through mostly closed compression molding tools (30, 32). The adhesive film (42) bonds the adjacent layer (44) to the upper surface of the lay-up (10), the sealing layer (44) becomes soft enough to seal around the fiber (20) at a temperature lower than the temperature at which the resin (16) exhibits a low enough viscosity to leak out of the lay-up (10), thereby preventing the resin from leaking out of the lay-up (10) during lay-up consolidation, the strain relief layer (46) provides a rubber strain relief for the optical fiber (20), and the plug (48) supports the layers (47) during consolidation.

Abstract: The communications system transmits both communications signals and electrical power to a plurality of subscribers. The communications signals can include video, voice and data signals. The communications system includes a coaxial drop cable for transmitting both the communications signals and electrical power from a cable tap to at least one subscriber of the communications system. The coaxial drop cable includes an annular outer conductor surrounding the dielectric material and having a mechanically and electrically continuous, non-overlapping tubular metallic shield. The coaxial drop cable has predetermined signal transmission characteristics, including enhanced shielding properties, which are maintained while the coaxial drop cable is flexed due, at least in part, to an increase in the stiffness of the dielectric material relative to the outer conductor. In particular, the dielectric material has a predetermined compressive stiffness of at least 1000 pounds per linear inch while the outer diameter of the outer conductor is less than about 0.04 inches. In addition, the outer conductor typically has a predetermined thickness which is at least 2.5 % of the outer diameter of the outer conductor. Accordingly, the coaxial drop cable effectively transmits both communications signals and electrical power while providing enhanced shielding and relatively low electrical resistance and attenuation.
