  • Patent number: 8074596
    Abstract: An apparatus and a method for forming a sheath over an elongate member comprises an extruder that has an output to supply a melt material having a temperature. A heat exchanger connected downstream the output of the extruder removes heat from the melt material in a controlled manner. An elongate member, which may be a cable core, is supplied to a crosshead that is connected downstream the heat exchanger to surround the elongate member with a sheath of the melt material.

  • Publication number: 20090257721
    Abstract: An optical transmission element has a number of optical waveguides, which are arranged as a bundle and are embedded in a filling composition. The optical waveguides and the filling composition are surrounded by a tube. A material comprising a resin, which for example contains an acrylate enriched with a filler, is used as materials for the tube. By mixing photoinitiators into the material comprising the resin of the tube, the tube material of the tube can be cured by irradiation with ultraviolet light. The use of a material comprising resin in the production of the tube of the optical transmission element allows thin buffering layers to be produced at a high material processing speed.

  • Patent number: 7599590
    Abstract: An optical cable comprises a swelling yarn, around which several optical transmission elements in the form of micromodules are arranged. A micromodule comprises a bundle of optic fibers, which are surrounded by a sleeve made from a material of plastic. Further swelling yarns are arranged around the optical transmission elements. The optical transmission elements and the swelling yarns are surrounded by a sleeve of paper. The paper sleeve is surrounded by a cable jacket made from a material of plastic. When an optic fiber is exposed, the cable jacket is pulled off, whereupon the paper sleeve tears off and can consequently be easily removed.

  • Publication number: 20080279514
    Abstract: An optical cable comprises a buffered optical fiber which is arranged within a buffer tube. The buffer tube is extruded around the buffered optical fiber such that a small gap, preferably in a range between about 40 ?m and about 100 ?m, is formed between the buffered optical fiber and the buffer tube. A layer of strength member elements is disposed around the buffer tube. A cable jacket is extruded around the strength member elements wherein the strength member elements are bonded to the cable jacket.
