    摘要： The invention pertains to an optical connector assembly having an alignment mechanism for coupling two single-lens, multi-fiber optical connectors together. Particularly, each connector comprising a single lens through which the light from multiple fibers is expanded/focused for coupling to corresponding fibers in a mating connector. In one aspect of the invention, the alignment mechanism includes mating features extending from the fronts of the lenses having substantially longitudinal surfaces that meet and contact each other when the two connectors are coupled together in only one or a limited number of rotational orientations relative to each other to as to properly rotationally align the multiple fibers in the two mating connectors. This mechanism also helps align the two connectors with the optical axes of their lenses parallel to each other. In another aspect of the invention to even more effectively align the two connectors with their optical axes parallel to each other, the connector assembly includes an alignment sleeve into which the front of each lens extends when mated, an inner diametrical surface of the alignment sleeve contacting an outer diametrical surface of each of the two lenses over a substantial longitudinal portion of each lens. The alignment sleeve may, for instance, be a resilient split sleeve that expands radially to accept the lenses.

    摘要： This invention is related to a fiber optic connector 10 including a precision ferrule 12 that is mounted in a machined tubular housing 40. An overmolded collar 70 secures the ferrule 12 to the housing 40 without the use of adhesives. Protruding lobes 26 on the ferrule 12 are received in a housing counterbore section 46 and the collar body 72 is molded around these lobes 26 to secure the ferrule against translation and rotation. The overmolded collar body 72 also engages a knurled surface 52 on the exterior of the tubular housing 40. The overmolded version of this connector 10 can be used with an epoxyless optical fiber termination. A press fit connector 110 is also disclosed.

    摘要： A method of terminating a fiber in a connector using a device comprising: (a) positioning a stripped fiber on the device such that the bare fiber portion extends into a first fiber channel of a cleaver; (b) securing the fiber to a fiber retainer slidably attached to the substrate to move along an x axis at a first position; (c) cleaving the bare fiber portion to form a cleaved end; (d) sliding the fiber retainer away from the cleaver along the x axis; (e) causing to be presented a second fiber channel of a connector held in a connector retainer along the x axis; (f) sliding the fiber retainer to the first position along the x axis, thereby causing the cleaved end to extend into the second fiber channel; and (g) actuating the connector while the fiber retainer is at the first position.
