Abstract: Embodiments of the invention include an optical fiber cable. The optical fiber cable includes a plurality of multi-fiber unit tubes. The multi-fiber unit tubes are substantially circular and dimensioned to receive a plurality of optical fibers. The optical fiber cable also includes a plurality of partially bonded optical fiber ribbons positioned within at least one of the multi-fiber tubes. The partially bonded optical fiber ribbons are partially bonded in such a way that each partially bonded optical fiber ribbon is formed in a random shape. The partially bonded optical fiber ribbons also are partially bonded in such a way that the plurality of partially bonded optical fiber ribbons are randomly positioned within the multi-fiber unit tube. The optical fiber cable also includes a jacket surrounding the plurality of multi-fiber unit tubes.

Abstract: An optical fiber distribution or breakout cable for serving multiple customer premises in a multi-dwelling unit (MDU) building. The cable contains a number of bend insensitive fibers each having a different colored coating for identification. A jacket of a flame-retardant polymer compound is extruded to surround the fibers. The jacket is sufficiently opaque to hide the color coated fibers at least partially from view, and the outer diameter of the jacket is not more than about 3.5 mm. A procedure for installing the cable through a hallway of a MDU building so as to lessen any negative visual impact of the installation on observers nearby is also disclosed.

Abstract: Embodiments of the invention include a compression-resistant seismic optical fiber cable for repeated deployment. The seismic optical fiber cable includes a central core tube dimensioned to receive at least one bundle of optical fibers. The central core tube is dimensioned to allow the optical fibers in the at least one bundle of optical fibers to relax relative to the other optical fibers. The seismic optical fiber cable also includes at least one strength member layer surrounding the central core tube. The strength member layer provides flexibility and tensile strength to the seismic optical fiber cable. The seismic optical fiber cable also includes a jacket surrounding the strength member. The seismic optical fiber cable also includes at least one rigid fiber reinforced composite rod linearly applied within the jacket. The one linearly-applied rigid fiber reinforced composite rod provides compressive resistance for the seismic optical fiber cable.

Abstract: 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. The protective jacket is relatively thick and rigid, having a thickness of 0.7-3.0 mm, and a modulus greater than 240 MPa.
