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.

Abstract: Certain embodiments of the invention may include systems and methods for providing tight-buffered optical fiber having improved fiber access. According to an example embodiment of the invention, a method for making a tight buffer upcoated optical fiber having a predetermined buffer stripping force is provided. The method includes controlling residual acrylate unsaturation (RAU) and oxygen in at least an outer surface of un-buffered optical fiber to achieve a predetermined buffer stripping characteristic, applying a tight buffer composition comprising acrylate to the un-buffered optical fiber, and curing the tight buffer composition.

Abstract: Certain embodiments of the invention may include a UV curable acrylate buffer coating for optical fiber. According to an example embodiment of the invention, a buffered optical fiber is provided. The buffered optical fiber includes a core, a cladding surrounding the core, a primary layer surrounding the cladding, a secondary layer surrounding the primary layer. A clear or translucent buffer surrounds the optical fiber, wherein the buffer includes polyester/polyether polyol aliphatic urethane acrylate, and the buffer has an elastic modulus greater than 40,000 psi.

Abstract: Dual coated optical fiber cables are optimized for air blown installation. The elastic properties of both coatings are controlled within a desired range over the full range of potential installation temperatures, e.g. 0-45° C. The material of the inner coating has a Tg below ?15° C., and preferably below ?25° C., and the material of the outer coating has a Tg above 60° C., and preferably above 75° C.
