摘要： A fiber-optic cable having optical fibers that are arranged as a rollable ribbon. Water-swellable material (e.g., superabsorbent liquid, superabsorbent powder, superabsorbent adhesive, etc.) is applied directly to the rollable ribbon, thereby eliminating the need to incorporate conventional water-absorbing yarns, tapes, or other such similar materials. The rollable ribbon is surrounded by a tube, with a dielectric strength member positioned external to the tube and substantially parallel to the tube. A jacket, with a ripcord along a substantial length of the jacket, surrounds the tube. Also taught is a process for manufacturing a rollable-ribbon fiber-optic cable, in which a water-swellable material is applied directly to the rollable ribbon, thereby eliminating the need to incorporate conventional water-absorbing yarns, tapes, or other such similar materials.

摘要： An optical fiber distribution cable for servicing living units inside a MDU building, is formed by surrounding differently colored optical fibers with a jacket having a diameter of not more than about 3.5 mm. The jacket is opaque for hiding the colored fibers at least partially from view, thus reducing or eliminating any negative visual impact of the cable when installed. The colored cable fibers are arranged so that they are visible to an installer when only the cable jacket is cut open. Connection modules are mounted at corresponding living units, and a section of the cable is placed in each module. The jacket on a cable section in a given module is cut open, and a fiber assigned to the corresponding living unit is identified by color. The fiber is cut, and a length of the fiber is removed from the cable section and stored in the given module.

摘要： A method of treating a buffered optical fiber or jacketed cable having a relatively low surface energy, e.g., fibers or cables that meet low smoke zero halogen (LSZH) standards, so they can be bonded to a supporting substrate at a customer premises by a water soluble, non-flammable adhesive. One or more burners produce a flame that treats the surface of the fiber or cable by oxidizing the surface as the fiber or cable moves past the burners. The surface energy increases enough for the adhesive to wet the surface so that, when cured, the adhesive bonds the fiber or cable to the supporting substrate. In another embodiment, a blown-ion discharge is directed at a determined rate over the surface of the fiber or cable, thereby treating the surface by removing contamination and micro-etching, and increasing the surface energy enough for the adhesive to wet the surface.

摘要： The embodiments disclosed herein seek to eliminate substantially all of the voids or air gaps among neighboring fibers within a CFU by wetting a plurality of optical fibers that comprises the CFU with an acrylate prepolymer resin before the plurality of the optical fibers are grouped together tightly. In one embodiment, instead of extruding a first acrylate prepolymer resin to the optical fibers immediately after a first die, the disclosed process wets the optical fibers with a first acrylate prepolymer resin prior to the first die.

摘要： A high count optical fiber cable is formed of a number of sub-unit components stranded around a central tension member. Each sub-unit component is formed to include the total number of individual fibers required to populate a given equipment rack (e.g., 288 fibers, for example). The individual fibers are preferably provided using a plurality of rollable optical fiber ribbons (permitting the large number of individual fibers to be compacted into a relatively small space), with water blocking material included in each sub-unit component. The sub-unit components may be formed to include individual strength members (i.e., in the form of sub-unit cables), or as loose tubes with an outer strength member disposed to surround the sub-units. Each sub-unit component is specifically sized to match the fiber capacity of, for example, a full equipment rack, minimizing the number of physical cables required for high density applications (e.g., data centers).

摘要： 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.

摘要： An optical fiber cable comprising 200 micrometer (μm) optical fibers (fibers with an outer diameter of approximately 200 μm) that are located within buffer tubes. This permits fiber packing densities of 3.8 fibers/mm2 or higher. The buffer tubes have wall thicknesses (tbuffer) between approximately 7.5 percent (7.5%) and approximately 30% of the buffer tube's outer diameter (ODbuffer), and a Young's modulus that is between approximately 750 mega-pascals (MPa) and 2,200 MPa, thereby providing the necessary structural integrity to resist kinking yet maintain flexibility.

摘要： A thread for tying a group of fibers in a fiber optic cable having an outer jacket to one another to form a fiber bundle. The thread includes a length of a binder thread, and an adhesion material coated on the binder thread so that (a) the binder thread adheres to the group of optical fibers about which the thread is tied to form the fiber bundle, and the binder thread remains adhered to the bundled fibers to restrain movement of the fibers when the outer jacket and cable elements other than the bundled fibers are removed. After the binder thread is tied about a fiber bundle, exposed surfaces of the adhesion material coated on the binder thread are treated so that the thread does not adhere to any cable elements in proximity to the thread, other than the fibers of the bundle about which the thread is tied.
