Abstract: A preconnectorized outdoor cable streamlines the deployment of optical waveguides into the last mile of a optical network. The preconnectorized outdoor cable includes a cable and at least one plug connector. The plug connector is attached to a first end of the cable, thereby connectorizing at least one optical waveguide. The cable has at least one optical waveguide, at least one tensile element, and a cable jacket. Various cable designs such as figure-eight or flat cables may be used with the plug connector. In preferred embodiments, the plug connector includes a crimp assembly having a crimp housing and a crimp band. The crimp housing has two half-shells being held together by the crimp band for securing the at least one tensile element. When fully assembled, the crimp housing fits into a shroud of the preconnectorized cable. The shroud aides in mating the preconnectorized cable with a complimentary receptacle.

Abstract: A fiber optic cable is provided that includes a plurality of lengthwise extending, non-jacketed bundles of optical fibers and a cable jacket surrounding the bundles of optical fibers. Each bundle of optical fibers may include a binder, such as a binder thread, for maintaining the integrity of the bundle. The binder may include, for example, a binder thread formed of an air entangled, textured, continuous multi-filament thread. The fiber optic cable may also include a separation element for preventing adhesion between the bundles of optical fibers and the cable jacket without having to separately jacket each bundle of optical fibers.

Abstract: A self-supporting fiber optic cable includes a messenger section having at least one strength and anti-buckling member enclosed within a jacket and a carrier section enclosed within a jacket that is joined to the jacket of the messenger section by a web. In a preferred embodiment of the present invention, carrier section does not include strength members and the optical fibers are set with a high EFL. The greater EFL accommodates elongation of carrier section without transmission of stress to optical fibers. In addition, the preferably generally cylindrical internal surface of a tube or jacket curves the optical fibers creating EFL, for example, the fibers are guided by the internal surface in a helical path. Resistance to carrier section elongation and contraction can be controlled by varying the length of the web connecting the carrier and messenger sections.

Abstract: A fiber optic cable having strength assemblies (30) adjacent a tube having at least one optical fiber therein, at least one of the strength assemblies including a strength member for imparting crush resistance to the cable. The strength member is generally coupled to a first jacket, and may be surrounded by a single jacket, or by an armor tape and a second jacket. The strength member may be disposed in a recess of the tube. When crush loads are applied to the fiber optic cable, the stresses created in the cable are advantageously distributed by strength assemblies (30) whereby stress concentrations and undue deflection of the cable in response to the crush loads are avoided. The arrangement of the cable components and strength assemblies (30) inhibits slippage and/or warping of the components under stress, and thereby evenly distributes the stress for preventing crush induced attenuation in the optical fibers.

Abstract: A fiber optic cable having strength assemblies (30) adjacent a tube for imparting crush resistance to the cable, at least one of the strength assemblies including a strength member in contact with a tube having at least one optical fiber therein.

Tight coupling and minimized gaps between the cable components in strength assemblies (30) inhibits slippage and/or warping of the components under stress, and thereby evenly distribute the stress for preventing crush induced attenuation in the optical fibers.

Abstract: A self-supporting fiber optic cable includes messenger and carrier sections and at least one interconnecting web. The messenger section includes at least one support member and a protective jacket. The carrier section includes a tube, at least one optical fiber disposed within the tube, and a jacket. In order to protect the optical fiber from tensile forces and to facilitate mid-span access, the carrier section can have an overlength. In order to accommodate the overlength, the web can include a plurality of intermittent webs that permit the carrier section to bend. The carrier section can also include at least one strength member. The at least one strength member is preferably positioned in a reference plane that also generally extends through the messenger section, the carrier section and the web. By appropriately positioning the strength members relative to the tube, the carrier section preferentially bends in a plane generally orthogonally disposed to the reference plane.

Abstract: A fiber optic cable (10) having a core tube (14) with a stack of optical fiber ribbons (12) therein, a jacket (20), and strength sections (30). Jacket (20) includes a non-uniform profile with close profile sections (22) and extended profile sections (26). Strength sections (30) comprise extended profile sections (26), dielectric strength rods (32), and ripcords (34) disposed between the strength rods. When it is desired to prepare fiber optic cable (10) for a cable pulling operation, portions of extended profile sections (26) are removed thereby exposing strength rods (32) and grip surfaces (22a) for receiving a pulling-grip (40). The compact size, flexibility, and light-weight construction of fiber optic cable (10) makes it a craft-friendly cable which is easy to route through cable passageways during the cable pulling operation.

Abstract: A fiber optic cable (10) includes a tube section (20) and an sheath section (40). Between tube and sheath sections (20,40) is a series of general interstices (S), each general interstice (S) comprises a respective set of sub-interstices (S1,S2,S3). Each general interstice (S) comprises a respective interstitial assembly (30). Each interstitial assembly (30) provides crush strength resistance and water blocking features to fiber optic cable (10).

Abstract: An optical fiber cable having a minimum bend radius and comprising at least one U-shaped carrier helically stranded about a coaxial rod having a central axis and including in its lateral peripheral surface at least one groove, said groove containing at least one optical fiber element, is characterized in that the maximum compressive force on said U-shaped carrier caused by bending the cable to its minimum bend radius is less than the minimum such force which could cause said U-shaped carrier to buckle toward said groove. A cable with 16-fiber ribbons containing 250 .mu.m outer diameter (OD) fibers may contain up to 3200 optical fibers. The cable cross-section packing density may be 2.13 fibers/mm.sup.2.
