    摘要: A light waveguide is protected with a protective covering loosely surrounding the waveguide, which covering is constructed of an inside layer and an outside layer. The inside layer is composed of a material selected from a group consisting of polycarbonate, polyether sulfone and polyetherimide while the outside layer is composed of a material selected from a group consisting of polyester, polyether, polyurethane, copolymers of these polymers as well as block polymers of each of these polymers. The selection of these materials with the two layers provides a good connection between the two layers of the covering.

    摘要: The invention concerns a method for securing cables or elongate hollow sections in duct or pipe systems for flowing media, and a cable network in a duct or pipe system. The cable or elongate hollow section to be laid is anchored by high-tensile-strength elements between anchoring points. The high-tensile-strength element may be a separate element or an element incorporated in the cable sheath or in the hollow section. Furthermore, the invention concerns the reduction of sags.

    摘要: A method and apparatus for the manufacture of optical transmission elements comprising a bundle of at least one light waveguide lead having a coating of filling material and receiving an outer envelope, characterized by the method, including applying a first coating of filling material to the bundle, stripping a portion of the material from the coated bundle, applying a second coating and then, subsequently applying the envelope. By stripping a portion of the first coating of filling compound or material, air or gas bubbles in the filling compound will be stripped from the coated bundle and reduce the chance of damage to the light waveguide leads.

    摘要: A cable network in a duct or pipe system for flowing media has a cable anchored by high-tensile-strength elements between anchoring points in the duct or pipe system. The high-tensile-strength element may be a separate element on which the cable is attached or an element incorporated in the cable sheath. The method includes providing anchoring elements on the interior of the ducts or pipes of the system, and either securing a cable with a high-tensile-strength element to the anchoring elements or securing the high-tensile-strength element to the anchoring elements and then fastening the cable to the tension element.

    摘要: An optical cable comprising a carrier member extending in a longitudinal direction and having outwardly accessible chambers receiving light waveguides, each of said chambers being separated from one another by a web characterized by a depression being formed in each of said webs to enlarge the heat-emitting surfaces and to remove undesirable accumulation of material in the region of the carrier members. The depressions preferably have a V-shaped cross section, and are smaller than the channels and are able to receive additional elements, which may include waveguides, tensile elements or electrical conductors. Each of the V-shaped depressions can also e used as a gas channel when the optical cable is to operated in a gas-pressure monitored fashion.

    摘要: An optical fiber having a multiple layer coating characterized by the inside layer being composed of a material that is stretched onto the bare fiber. Preferably, the inside layer is applied by extruding a stretch cone and stretching this onto the fiber. An intermediate layer can be applied onto the inside layer, either by a pressure molding system or by a stretched cone method, and an outside layer is applied by another extruder forming a stretched cone.
