Abstract: A tape can comprise a dielectric film that has a pattern of electrically conductive areas adhering thereto. The conductive areas can be electrically isolated from one another. The tape can utilize means to obscure the metallic finish and can contain indicators to deter installers from grounding the tape at either end. The tape can be wrapped around one or more conductors, such as wires that transmit data, to provide electrical or electromagnetic shielding for the conductors. The resulting cable can have a shield that is electrically discontinuous between opposite ends of the cable.

Abstract: A tape can comprise a two-sided strip of dielectric material, with patches of electrical conductive material adhering to each side. Patches on one side can be longitudinally offset from patches on the opposite side. The patches can be electrically isolated from one another. The tape can be wrapped around one or more conductors, such as wires that transmit data, to provide electrical or electromagnetic shielding. The patches can circumferentially encase the conductors, with patches on one side of the tape covering gaps on the other side of the tape. The tape can be wrapped around the conductors so that an edge of a patch spirals about the conductors in a rotational direction opposite to any twisting of the conductors. The resulting cable can have a shield that is electrically discontinuous between opposite ends of the cable.

Abstract: A communication cable for transmitting various communication signals. The cable comprises buffer tubes for optical fiber cables that are robust, crush resistant, flexible, and cost effective. To obtain these properties, the buffer tubes contain a polymeric mixture of high impact polystyrene and styrene-butadiene-styrene. The polymeric mixture for the buffer tubes may also contain crystalline polystyrene and/or acrylonitrile-butadiene-styrene.

Abstract: A buffer tube for use in a fiber optic cable is disclosed. The buffer tube has a flexural modulus greater than about 180 kpsi and less than about 370 kpsi, which results in a buffer tube having good crush resistance and flexibility. A particularly useful buffer tube material is an alloy of polypropylene and polyphenylene oxide, which may contain solid fillers.

Abstract: The invention relates to a method of manufacturing an optical conductor, in which method, a mixture of a resin and of a photo-initiator is exposed to UV radiation in order to form, by cross-linking, the covering of the optical conductor. The cross-linking takes place by causing the conductor (10) to advance past a UV source at a speed of at least 10 meters per minute (m/min). The invention provides a first source (18) which emits monochromatic UV radiation to achieve cross-linking mainly on the surface, and a second UV source which emits UV radiation of broad spectrum containing wavelengths that are longer than the wavelength of the monochromatic source to achieve cross-linking mainly in depth.
