    摘要： The present disclosure relates to a fiber optic cable including an outer jacket having an elongated transverse cross-sectional profile defining a major axis and a minor axis. The transverse cross-sectional profile has a maximum width that extends along the major axis and a maximum thickness that extends along the minor axis. The maximum width of the transverse cross-sectional profile is longer than the maximum thickness of the transverse cross-sectional profile. The outer jacket also defines first and second separate passages that extend through the outer jacket along a lengthwise axis of the outer jacket. The second passage has a transverse cross-sectional profile that is elongated in an orientation extending along the major axis of the outer jacket. The fiber optic cable also includes a plurality of optical fibers positioned within the first passage a tensile strength member positioned within the second passage. The tensile strength member has a highly flexible construction and a transverse cross-sectional profile that is elongated in the orientation extending along the major axis.

    摘要： Robust fiber optic cables and assemblies having low attenuation multimode optical fibers (402). The cables have low attenuation in tensile and mandrel wrap tests, and can have thermoplastic urethane jackets (410) coextruded over tensile strength members (420) that allow the cables to be pulled by the jackets. The cables have relatively small cross-sections yet have sufficient robustness to be deployed in extreme environments such as cellular tower applications.

    摘要： A fiber optic cable includes at least one optical fiber, at least one strength member, at least one dry insert, and a cable jacket. The cable jacket has a cavity with a generally rectangular cross-section with the at least one optical fiber and the at least one dry insert disposed therein. The at least one optical fiber has a predetermined level of coupling to the cable jacket that is provided by the at least one dry insert within the cavity of cable jacket. The predetermined level of coupling is about 0.1625 Newtons or more per optical fiber for a thirty meter length of fiber optic cable. Additionally, fiber optic cables of the present invention are also suitable as a portion of a cable assembly.

    摘要： Described are new cable designs for indoor installations wherein the cable comprises a dual-layer optical fiber buffer encasement of acrylate resin. The buffer encasement has an acrylate compliant inner layer that protects the fiber and minimizes stress transfer to the fiber; and a hard, tough acrylate outer layer that provides crush resistance. The dual-layer optical fiber buffer encasement is wrapped with reinforcing yarn and encased in an outer protective jacket. A dual jacket embodiment adapted for indoor/outdoor installations is also described.

    摘要： A filler rod (24a-24c) for occupying space in a stranded optical fiber communications cable (10) having at least one buffer tube (12a-12c) containing at least one optical fiber (14) is disclosed. The filler rod comprises an elongated rod extruded from a polypropylene homopolymer, a polypropylene-polyethylene copolymer (i-PP) resin material, or preferably, from a polypropylene-polyethylene copolymer having a nucleating agent disbursed therein. The resin material is foamed during extrusion so as to have a plurality of void spaces therein and a relative density which is less than 1 relative to the unfoamed resin material. As compared to rods made from high density polyethylene, the i-PP filler rods show a greater foaming efficiency, more efficient use of material, an improved combination of mechanical properties and density, reduced post-extrusion shrinkage and a substantial reduction in the sticking of the filler rods to the outer jacket that is experienced with high density polyethylene filler rods.
