摘要： Disclosed is a reduced-diameter optical fiber that employs a novel coating system. When combined with a bend-insensitive glass fiber, the novel coating system according to the present invention yields an optical fiber having exceptionally low losses.The coating system features (i) a softer primary coating with excellent low-temperature characteristics to protect against microbending in any environment and in the toughest physical situations and, optionally, (ii) a colored secondary coating possessing enhanced color strength and vividness. The secondary coating provides improved ribbon characteristics for structures that are robust, yet easily entered (i.e., separated and stripped).The optional dual coating is specifically balanced for superior heat stripping in fiber ribbons, with virtually no residue left behind on the glass. This facilitates fast splicing and terminations. The improved coating system provides optical fibers that offer significant advantages for deployment in most, if not all, fiber-to-the-premises (FTTx) systems.

摘要： An apparatus and method efficiently focuses laser light to a target fiber to rapidly and evenly cure a coating on the fiber and to increase a draw rate for the fiber. The laser light is expanded and refocused to a strip of light having a diameter that is a multiple of the fiber diameter. The strip of light is applied to one side of the fiber and a reflection of the strip of light is focused to a second side of the fiber to provide uniform radiation of the fiber.

摘要： A non-carbon black pigment blend is mixed with a coating layer of an optical fiber to provide a black appearing colored optical fiber. The pigment blend does not absorb UV light and is formed by blending three primary colors including red, blue and yellow. The combination of these three primary colors creates a black appearing colored secondary coating. The proportions of the primary colors are controlled to provide the desired shade of black with, in general, no one coloration of pigment exceeding 45% by weight of the total pigment added to the secondary coating. The pigment blend may further include white pigment to provide a slate tone black appearing color. The proportion of white pigment, in general, not exceeding 10 percent by weight of the total pigment added to the secondary coating. The pigment is mixed as a concentrate which is added to a secondary coating layer for application to the optical fiber. Typically, the pigment concentrate is premixed with the secondary coating layer; however, the pigment may also be directly combined with the secondary coating material during application to the optical fiber. The optical fiber may include one or more secondary coating layers, with the pigment concentrate being combined with the outermost secondary coating layer on the optical fiber.

摘要： A grease composition comprising oil, colloidal particle filler, and, optionally, a bleed inhibitor is disclosed. The grease typically has a critical yield stress below 140 Pa at 20.degree. C., preferably below 70 or 35 Pa. The grease can advantageously be used as a cable filling material, especially for optical fiber cable. In the latter case it can result in cable having substantially no cabling loss. Preferred compositions comprise 77 to 95% b.w. of ASTM type 103, 104 A, or 104B paraffinic or naphthenic oil, or polybutene oil; 2 to 15% b.w. of hydrophobic or hydrophilic fused silica; and optionally, up to 15% b.w. of styrene-rubber or styrene-rubber-styrene block copolymer, or semiliquid rubber.
