    Abstract: Embodiments of the invention include an optical fiber ribbon having a low Young's modulus bonding matrix material. The optical fiber ribbon includes a plurality of optical fibers arranged adjacent to one another in a linear array. The optical fiber ribbon also includes a plurality of bonding matrix material portions applied to at least a portion of the outer surface of at least two adjacent optical fibers. The bonding matrix material portions have a low Young's modulus. Also, the plurality of bonding matrix material portions are applied to at least a portion of the outer surface of at least two adjacent optical fibers in such a way that the linear array of optical fibers forms a partially bonded optical fiber ribbon.

    Abstract: Embodiments of the invention include a method for making a partially bonded optical fiber ribbon. The method includes providing a linear array of optical fibers, and applying a bonding matrix material randomly to at least a portion of at least two adjacent optical fibers. The bonding matrix material is applied randomly to the adjacent optical fibers in such a way that the linear array of optical fibers forms a partially bonded optical fiber ribbon. The bonding matrix material applied randomly to the adjacent optical fibers is dense enough to allow the resulting partially bonded optical fiber ribbon to lay substantially flat. Also, the bonding matrix material applied randomly to the adjacent optical fibers is sparse enough to allow the resulting partially bonded optical fiber ribbon to be rolled into a substantially circular shape.

    Abstract: A tight-buffered optical fiber cable includes an improved method of accessing the coated optical fiber. The cable can include an optical fiber having a glass core and a cladding layer. One or more coating layers can be applied about the cladding layer. A buffer jacket material can be applied onto an outer surface of the outer coating layer as a buffer jacket outer layer. The buffer jacket outer layer can have distinctive features including a low tear strength, low elastic modulus, high elongation percentage, and low peeling force. This can allow a user of the optical fiber cable to separate at least a portion of the coated optical fiber from the buffer jacket outer layer by grasping a free end of the coated optical fiber and pulling it through the outer wall of the buffer jacket outer layer, thereby tearing through the outer wall of the buffer jacket outer layer.

    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.

    Abstract: In curing a matrix material of a rollable optical fiber ribbon, ultraviolet light may be concentrated in a selected range of wavelengths to avoid further curing the primary coating of each fiber. A ribbon may be made by aligning the fibers, each having at least a primary coating, into a ribbon shape, applying a matrix material in intermittently distributed portions along the ribbon-shaped group of fibers, and exposing the ribbon-shaped group of fibers and applied matrix material to ultraviolet light concentrated in a range of wavelengths absorbed more by the matrix material than by the primary coating.

    Abstract: A method for splicing a first optical fiber ribbon cable to a second optical fiber ribbon cable includes separating an end of the first optical fiber ribbon cable into loose optical fibers, and re-ribbonizing the loose optical fibers into a ribbonized end having a second pitch different from the first pitch of the original first optical fiber ribbon cable. The method further includes inserting the ribbonized end into a mass fusion splicer having the second pitch, and splicing the ribbonized end to the end of the second optical fiber ribbon cable using the mass fusion splicer.

    Abstract: Embodiments of the invention include a method for making a partially bonded optical fiber ribbon. The method includes providing a linear array of optical fibers, and applying with an ink jet printing machine a bonding matrix material to at least a portion of at least two adjacent optical fibers. The applied bonding matrix material has a viscosity of approximately 2.0 to approximately 10.0 centipoise (cP) measured at 25 degrees Celsius (° C.). The applied bonding matrix material also has a conductivity of approximately 600 to approximately 1200 millimhos (mmhos). The applied bonding matrix material also has an adhesion of approximately 0.01 to approximately 0.20 Newtons (N). Also, the bonding matrix material is applied to at least a portion of at least two adjacent optical fibers in such a way that the linear array of optical fibers forms a partially bonded optical fiber ribbon.
