摘要： Fiber optic bundles include helically stranded subunit cables. The assemblies have small cross sections and low bend radii while maintaining acceptable attenuation losses. Binders can be omitted to improve ease of processing and installation. Helically stranding of the subunit cables allows ease of access to the individual cables during installation.

摘要： A fiber optic ribbon cable includes a jacket of the cable, the jacket having a cavity defined therein, an optical element including an optical fiber and extending within the cavity of the jacket, and a dry water-blocking element extending along the optical element within the cavity. The dry water-blocking element is wrapped around the optical element with at least a portion of the dry water-blocking element disposed between another portion of the dry water-blocking element and the optical element, thereby defining an overlapping portion of the dry water-blocking element. The optical element interfaces with the overlapping portion to provide direct or indirect coupling between the optical element and the jacket.

摘要： Fiber optic cables and assemblies useful for distribution of the optical fibers to a network are disclosed. The fiber optic cables include a first strength component and a second strength component with a cable jacket generally surrounding the first and second strength components. One or more compartments are defined between the first and second strength components for housing one or more optical fibers. The optical fibers of the fiber optic cable are easily accessible by the craft for distribution to the network, thereby allowing the construction of assemblies that are suitable for distribution of the optical fibers to the network.

摘要： Disclosed are fiber optic cables having a cable jacket or buffer tube with a cavity. Disposed within the cavity are at least one optical fiber and a coupling agent. The coupling agent acts to couple the at least one optical fiber to the cable jacket or buffer tube with a predetermined force, but the coupling agent does not substantially fill a cross-section area of the cavity, thereby providing a nearly “dry” fiber optic cable. Additionally, the fiber optic cable can optionally include one or more water-swellable components for blocking the migration of water within the cavity. Variations include fiber optic cables having the desired flame-retardant ratings for indoor use, outdoor cables with adequate water-blocking, and/or cables suitable for indoor/outdoor use.

摘要： A method of forming a low-cost drop cable (10) is disclosed. The method includes providing a protective cover material (352) having an extrusion temperature of 140° C.≦TE≦160° C. The protective cover material is extruded through a die (420) having a single aperture (424) that defines the cable's elongate cross-sectional shape. The extrusion process involves covering first and second strength members (30) on either side of at least one optical fiber (50). The combination of the low temperature of the extrudable protective cover material and the elongate shape of the single die aperture cause the formation of an oval cavity (20) within the extruded protective cover material. The oval cavity has major and central axes (A1, AC) and surrounds the at least one optical fiber. The strength members lie along the cavity major axis. Tensioning the strength members during extrusion and then releasing the tension causes the drop cable length to be reduced. This gives rise to an excess fiber length, which adopts a serpentine configuration substantially in a plane (PF) defined by the major and central axes (A1, A2) of the oval cavity.
