    摘要: The invention relates to coating composition, coated articles of manufacture, and to the formation of the coated articles. The coating is an energy-beam set resin containing fluid containing heat-expandable, fluid-encapsulating hollow spheres in the resin. The coating of a substrate, such as a communication line material, is accomplished by coating the material with a resin mixture containing expandable spheres and then exposing the coated material to an energy-beam source for a period of time to cure the resin and expand the spheres. The coating is applied to at least one filament of a communication line material. Such filaments can be gathered into bundles which are first extrusion coated with a thermoplastic polymer before being coated with the resin mixture. The composition of the resin material can be varied by changing the volume percent of the hollow spheres present in the resin mixture.

    摘要: The present invention relates to an adhesive for connecting and fixing an optical fiber to an optical connector and to an optical connector which uses that adhesive. The adhesive prevents deformation of the optical connector ferrule and stressing of the optical fiber due to hardening shrinkage during the hardening of the adhesive and/or a shrinkage during cooling of the adhesive. In accordance with the invention, (1) the value of (the coefficient of linear expansion (.degree.C..sup.-1) of the adhesive).times.(the difference between a hardening temperature of the adhesive and room temperature (.degree.C.)).times.(Young's Modulus (kg/mm.sup.2) of the adhesive) is equal to or less than about 2.5, (2) the value of (the rate of hardening shrinkage (%) of the adhesive).times.(Young's Modulus (kg/mm.sup.2) of the adhesive) is equal to or less than about 1000 and/or (3) the adhesive hardens at room temperature.

    摘要: A glass fiber for optical transmission comprising a glass fiber having provided thereon a first coating layer of a hardened resin and a second fluorine-containing resin layer formed by extrusion molding is disclosed. At least one of the first and second layers contains an adsorbable solid powder which is capable of adsorbing fluorine gas and/or hydrofluoric acid generated from the fluorine-containing resin during the extrusion molding. The glass fiber has an improved mechanical strength without adversely affecting transmission properties of the glass fiber.

    摘要: A method and apparatus for coating optical transmission glass fibers with a resinous composition. A vessel is provided through which a glass fiber is drawn. While it is being drawn through the vessel, the fiber is spun, and a resin coating is applied. In order to maintain the air pressure within the vessel fairly constant, an exhaust vent is provided through which excess particles of the resinous composition may escape. Turbulence is thus substantially reduced preventing the fiber from swinging and allowing the particles to be sprayed smoothly. Further, the particles may be electrically charged so that they are both attracted to the optical fiber and repel one another during flight. The invention employs both of these features to produce a uniform coat on an optical transmission glass fiber.
