  • Publication number: 20230384512
    Abstract: A delivery fiber assembly suitable for delivering broad band light and including a delivery fiber and a connector member. The delivery fiber has a length, an input end for launching light, and a delivery end. The delivery fiber includes along its length a core region and a cladding region surrounding the core region, the cladding region includes a cladding background material having a refractive index Nbg and a plurality of microstructures in the form of inclusions of solid material having refractive index up to Ninc and extending in the length of the longitudinal axis of the delivery fiber, wherein Ninc<Nbg. The plurality of inclusions in the cladding region is arranged in a cross-sectional pattern including at least two rings of inclusions surrounding the core region. The connector member is mounted to the delivery fiber at a delivery end section of the delivery fiber including the delivery end.

  • Patent number: 10495180
    Abstract: A wire rope assembly unit including a wire rope and a device for assembling the wire rope. The device is fastened at one end of the wire rope and has a connecting element arranged at the front on the end of the wire rope. The assembly unit has a sleeve that engages around an outer surface of an end section of the wire rope. The sleeve is made of a material of lesser rigidity than strands of the wire rope and, optionally, than the connecting element. The sleeve is pressed, hammered and/or rolled onto the wire rope and, optionally, onto the connecting element to produce a form-locked connection. Outer strands of the wire rope are separated from the wire rope in a rope section, in which the wire rope is arranged inside the sleeve, and the sleeve is connected to ends of the outer strands at its one edge.
