摘要： An optical fiber switching apparatus having a guide frame which is supported by an apparatus body. The guide frame has a guide groove. Disposed on the guide grooves is a movable moving member. The moving member can be moved by the apparatus along the guide groove. A slide terminal is connected by a support to the moving member. The support allows the slide terminal to approach the moving member and thereby causing the slide terminal to enter an unlocked position or to move away from the moving member and thereby causing the slide terminal to enter a locked position. The slide terminal support an end face of an optical fiber. The apparatus also includes a driving wire which has two end portions. The end portions are disposed through the moving member and are coupled to the slide terminal, thereby forming a loop in the driving wire. The apparatus can move the slide terminal by causing tension in the driving wire so as to cause the slide terminal to enter the unlocked position, and thereby allowing the moving member to-move along the guide groove by a longitudinal movement of the driving wire.

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： 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.
