Abstract: Embodiments of the invention include a system and method for color-coating an optical fiber. The system includes a flow controller that controllably delivers and mixes color concentrate from one or more color concentrate reservoirs with a coating material, which colored coating material is fed to a coating die through which optical fiber passes. The color concentrate reservoirs are more compact and can be made portable along with the flow controller. Thus, the entire color coating system can travel to any appropriate location in the fiber manufacturing facility, e.g., at any one of a number of draw towers. Such portability allows many different colors to be used at the same draw tower much more easily than conventional arrangements, which typically only have one color line per draw tower. The method includes providing an optical fiber, controllably delivering color concentrate with a coating material to a coating die, coating the optical fiber with the coating die, and curing the coated fiber.

Abstract: The specification describes optical fiber cables designed for microduct installations. The microduct cables are coated with a sheath having particulates added to modify the drag of the outer surface of the cable to air, and thereby facilitate air blown installation. The particulates are nanoclay, silica, alumina, or other suitable solid particles of less than 5 microns. The coating comprises a prepolymer containing the filler, and is UV cured.

Abstract: The present invention is directed to a system and method for use in a computing environment to provide high definition (HD) video content as part of a multimedia experience over computing networks such as Internet Protocol (IP) networks. The present invention provides an interactive entertainment system where HD video is provided in a personal computing environment through novel compression techniques and optimization for the rendering hardware. Further, the HD video is embedded into other multimedia offerings to allowing unprecedented interaction by end users.
