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 is an improved optical fiber cable specially adapted for seismic sensing. Compared with standard optical fiber cable, this improved optical fiber cable is reduced in size, lighter, and more flexible. These characteristics make the optical fiber cable more robust for reusable applications. Due to modifications in the design of the optical fibers, the size and weight of the seismic sensing cable may be substantially reduced. That allows longer lengths of seismic sensing cable, and more seismic sensor boxes, to be reeled on a given sized reel, and makes deployment of the seismic sensing cable faster, easier, and less expensive. A preferred cable design for reaching these objectives comprises multiple optical fibers, of a design just described, encased in a dual-layer optical fiber buffer encasement of acrylate resin.

Abstract: 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.

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.

Abstract: Embodiments of the invention include an optical fiber ribbon. 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 bonding matrix material applied to at least a portion of the outer surface of at least two adjacent optical fibers. The optical fiber ribbon also includes at least one marking applied to the outer surface of at least one optical fiber. The at least one marking is applied to the outer surface of at least one optical fiber in a manner that reduces the optical transmission loss of the optical fibers.

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: 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.
