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： A cable comprising a central member with a coating that is soft, and which deforms under compression. Ribbon stacks are then placed atop the soft material so that the bottoms of the ribbon stacks are in direct contact with the soft material, thereby causing the soft material to conform to the shape of the bottoms of the ribbon stacks.

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 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.

摘要： 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.

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.
