Patents by Inventor Heng Ly

Heng Ly has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9031369
    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.
    Type: Grant

  • Patent number: 8374473
    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.

  • Publication number: 20130011108
    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.

  • Publication number: 20050207716
    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.
