According to one embodiment, a fiber optic cable includes a plurality of optical fibers having a lay length of greater than 160 mm. The fiber optic cable also includes strength material surrounding the plurality of optical fibers and a polymer jacket surrounding the strength material. Each of the optical fibers is configured to exhibit a bend-induced optical attenuation of less than or equal to about 0.6 dB when wrapped one turn around a 7.5 mm mandrel.

Abstract: Armored fiber optic assemblies are disclosed that include a dielectric armor along with methods for manufacturing the same. The dielectric armor has an armor profile, thereby resembling conventional metal armored cable to the craft. The dielectric armor provides additional crush and impact resistance and the like for the optical fibers and/or fiber optic assembly therein. The dielectric armor is advantageous to the craft since it provides the desired mechanical performance without requiring the time and expense of grounding like conventional metal armored cables. Additionally, the armored fiber optic assemblies can have any suitable flame and/or smoke rating for meeting the requirements of the intended space.

Abstract: Disclosed are fiber optic assemblies having at least one optical fiber disposed within a tube and/or cavity along with a powder or powder blend that is at least partially mechanically attached thereto. In one embodiment, the powder or powder blend includes a water-swellable component that is mechanically attached to about 30 percent or less of the surface area of the tube wall while still effectively blocking the migration of water along the tube. Other embodiments may have the powder or power blend mechanically attached to the tube, cavity, or the like at relatively high percentage levels of the total powder or powder blend within the assembly, thereby inhibiting unintentional migration along the tube, cavity, or the like. Other embodiments may use powder or powder blends that may or may not include a water-swellable powder to provide other desired characteristics.

Abstract: A fiber optic cable including at least one optical fiber disposed within a cavity of a cable jacket and methods for manufacturing the same are disclosed. The cavity has a first cavity cross-sectional area and a second cavity cross-sectional area located at different longitudinal locations along the cable, where the first cavity cross-sectional area is greater than the second cavity cross-sectional area. The region of the second cavity cross-sectional area of the cable provides and/or increases the coupling level of the at least one optical fiber to the cable jacket. In further embodiments, the fiber optic cable is a dry cable having one or more dry insert within the cavity for cushioning and/or optionally providing water-blocking for the cable.

Abstract: A cable-stranding apparatus for performing SZ-stranding of strand elements about at least one core member is disclosed. A first stationary guide member individually guides the strand elements in a spaced apart configuration and centrally passes the at least one core member. At least one hollow-shaft motor is arranged downstream of the stationary guide member. A rotating guide member is disposed in the hollow shaft and rotates with the hollow shaft according to a rotation relationship. The rotation relationship controls the rotational speed and direction of the rotating guide member to SZ-strand the strand elements about the at least one core member to form an SZ-stranded assembly. Embodiments of cable-stranding apparatus having multiple hollow-shaft motors and respective multiple rotating guide members are also disclosed.

Abstract: An optical cable comprises a tight-buffered optical cable and a protective sleeve which surrounds the tight-buffered optical cable. An intermediate layer surrounds the protective sleeve has tension-resistant elements. Furthermore, the optical cable contains a cable sheath which surrounds the intermediate layer, and a transitional area facing its inner surface. In this transitional area, the material of the cable sheath is mixed with the tension-resistant elements of the intermediate layer.

Abstract: Cable-stranding methods for performing SZ-stranding of strand elements about at least one core member are disclosed. One method includes passing initially spaced apart strand elements through peripheral guide holes and passing at least one core member through a generally central location of at least one guide member. The method also includes actuating a controller that controls the rotation of the at least one guide member and rotating the at least one guide member to form the SZ-stranded assembly.
