    Abstract: A method for preparing a ferrule assembly avoids polishing while providing adequate control over fiber end protrusion and co-planarity. A distal end of the fiber is prepared before securing the fiber in a ferrule, and before or after inserting the fiber into the ferrule. The prepared fiber is manipulated to provide a desired spatial relationship between the fiber end and the ferrule's end face, and then secured to maintain the desired spatial relationship. Preferably, the fiber end is prepared using a laser cleaving technique to provide a suitable end without abrasive polishing. An interferometer may be used to obtain measurements, during manipulation of the prepared fiber within the ferrule, that indicate whether the prepared fiber is satisfactorily positioned. In accordance with other aspects of the invention, a ferrule assembly prepared in accordance with the method, and a connector or other optical package including such a ferrule assembly are provided.

  • Patent number: 8764316
    Abstract: A fiber optic connector includes a ferrule having a mating end and an insertion end and a ferrule holder having a first end portion in which the ferrule is received and a second end portion opposite the first end portion. The first end portion defines a first bore having a first bore width for receiving the ferrule. Additionally, the first end portion defines a bore surface and at least one groove formed in the bore surface. The at least one groove extends from where the insertion end of the ferrule is located within the first bore to a front face of the ferrule holder. Ridges are formed around the first bore because the at least one groove also extends in a circumferential direction. The ridges contact the ferrule and are deflected by the ferrule in a direction toward the insertion end of the ferrule.

  • Patent number: 8753021
    Abstract: An optical fiber may be secured to a ferrule of an optical connector with an adhesive mixture. The optical fiber may be secured by preparing an adhesive mixture, disposing the adhesive mixture in a fiber-receiving passage defining an inner surface of the ferrule, inserting the optical fiber into the fiber-receiving passage and into contact with the adhesive mixture, and curing the adhesive mixture. The adhesive mixture may be prepared by forming a base mixture that includes a base solvent, an alkyltrialkoxysilane, an aryltrialkoxysilane, and an aryltrifluorosilane. The adhesive mixture may be cured by heating to a temperature of at least about 200° C. and cooling to room temperature or below.

  • Patent number: 8702322
    Abstract: An optical fiber connector preloaded with an adhesive is provided. The optical connector includes an optical fiber-receiving passage. The passage includes a first passage section extending inwardly from the first face, and the first passage section has a first width. The passage includes a second passage section extending inwardly from the second face, and the second passage section has a second width. The second width is less than the first width. The passage includes a transition passage section located between the first passage section and the second passage section. The transition passage has a variable width, and the variable width of the transition section decreases as the distance to the second face decreases. A meltable adhesive composition is located within the transition passage section and is configured to bind an optical fiber to an inner surface of the second passage following melting and solidification of the adhesive composition.

  • Patent number: 8622633
    Abstract: A connector for one or more optical fibers has a ferrule into which the optical fibers are glued directly with their outer cladding. No stripping of the fibers is required any longer before gluing them to the ferrule and thus, the difficulty of the fragility of the stripped fibers is overcome. The fibers are special fiber having a primary coating with smaller tolerances of ±2 microns. The fibers are arranged on a flexible foil which forms an optical overlay for a printed circuit board.
