Abstract: A cable, specifically a data cable, which utilizes a T-shaped spline to separate four internal data cables. This cable is a specific form of a more general cable which utilizes a central spline which is designed to separate all but one pair of component cables to provide for material savings in cable construction which still sufficiently reducing cross-talk to meet data cable design specifications.

Abstract: Cables including a plurality of twisted pairs of insulated conductors and a jacket surrounding the plurality of twisted pairs of insulated conductors, the jacket including a plurality of protrusions extending away from an inner circumferential surface of the jacket toward a center of the cable. The plurality of protrusions are configured so as to hold the plurality of twisted pairs away from the inner circumferential surface of the jacket, and may provide an air gap between the plurality of twisted pairs of insulated conductors and the inner circumferential surface of the jacket.

Abstract: Multi-member cables which are comprised of two or more components (including component cables and non-cable components) held together by at least one adhesive element placed between the components, and methods for manufacturing such cables. Multi-member cables which are comprised of jacketed cables whose jackets are adhered together without the use of an adhesive element, such as by co-forming the jackets, and methods for manufacturing such cables are also discussed. Generally, the components will be separated from the multi-member cable by an installer, although other methods may also be used.

Abstract: A cable separator spline and a cable containing the cable separator spline in its core. The spline extends longitudinally and has a plurality of spaced longitudinally extending open pockets in which cables, such as twisted pair cables, can be placed and form part of the core. A cross-section of the spline has a major axis and a minor axis with the major axis being longer than the minor axis. At least one and preferably at least two pockets are on the major axis, and at least one and preferably at least two pockets are on the minor axis. The core containing the twisted pair cables in the pockets can of course be shielded and jacketed, just jacketed or any other desired cable construction that would benefit from the use of my elongated separator spline.

Abstract: An improved high performance twisted pair data cable (20) than has an impedance standard deviation of less than 3.5 when the standard deviation is calculated around an average impedance of 50 to 200 ohms and preferably 90 to 110 ohms. The twisted pair is helically wrapped with a metal shield tape (16) at a tension that provides a cross-sectional void of less than 25% and preferably less than 18% of the cross-sectional area of the shielded twisted pair cable. The tape is helically wrapped with an overlap of 30-45% and at an angle of 35-45 degrees with respect to the longitudinal axis of the cable. The cable has a rating up to 600 MHz.

Multi-member cables which are compromised of jacketed cables whose jackets are adhered together without the use of an adhesive element, such as by co-forming the jackets, and methods for manufacturing such cables are also discussed. Generally, the components will be separated from the multi-member cable by an installer, although other methods may also be used.

Abstract: We provide a high performance bound lateral shielded twisted pair cables, a high performance data cable containing at least four of the bound lateral shielded twisted pair cables, and a method for preparing the same. The bound lateral shielded twisted pair cables preferably have a 20° C. adjusted standard impedance deviation of 4.5 or less and the high performance data cable contains at least four of the bound lateral shielded twisted pair cables and has a 20° C. adjusted average standard impedance deviation of 4.5 or less. The twisted pair is laterally wrapped with a metal shield tape and a fabric or metal braid or thread at a tension that provides the above. The tension is such that it provides a cross-sectional void area of less than 25% and preferably less than 18% of the lateral shielded twisted pair cable cross-sectional area. The tape is laterally wrapped with an overlap of at least 10% . Preferably, the cables have a rating out to 600 MHz and 1000 MHz.

Abstract: A coaxial fiber optic cable which includes a core having a transmission medium that includes at least one optical fiber surrounded by one or more strengthening materials and enclosed by a core jacket. A first electrical conductor i.e., a copper braid surrounds the core jacket and is coaxial with the core jacket. A second electrical conductor, i.e., copper braid, is coaxial to the first conductor. The first and second copper braids are triaxial with the core jacket and are separated by a dielectric which extends between and in parallel relation to the length of the braids. An overall aramid reinforcement layer(s) is in the core and surrounds the optical fiber(s). An outer cable jacket surrounds the second electrical conductor and encloses the cable.

The shield has a thickness of up to about 6 mils. A helical groove formed in the shield, and an insulating jacket surrounding the shield.

Abstract: A gas blocked fiber optic cable (10). A cable (10) having a fiber glass epxoy rod (12) which is top coated with EVA-Copolymer (28) and surrounded by fiber optic cables (16). Optical fibers (16) are enclosed in buffer tubes (18) filled with gel (20). Interstitial filling (28) surrounds buffer tube (18). Acid terpolymer top coat (24) bonds filler (28) to buffer tubes (18) preventing gas migration throughout the length of the cable. Black thermo plastic elastomer (30) layer surrounds filler (28) which is surrounded by the outer most polyethylene jacket (32) which is UV resistant.

Abstract: A high resistivity cable for transmitting optical information. The cable includes a resilient buffer tube holding an optical conductor for transmitting the optical information. A high dielectric gel is packed inside of the tube to fill the space not occupied by the conductor. The cable also includes a flexible high dielectric braid surrounding the tube throughout its length for increasing the tensile strength of the cable. The interstices of the braid are filled with a high dielectric gel to prevent moisture from entering the braid. The cable also includes an electrically insulative resilient outer jacket. A method of manufacturing the cable is also disclosed.
