摘要:
An FDDI loopback connector or optical network is suitable for testing in fiber-to-fiber applications and designed to be interchangeable with a complimentary connector. The loopback tester is afforded a desired level of attenuation by providing a fiber loop having a controlled air gap. Adjustment of the air gap will afford a desired attenuation level.

An injection molded plastic fiber alignment ferrule is provided with a polishing pedestal. The ferrule has an opening therethrough for receiving the end of a fiber, which extends beyond the pedestal. The fiber is cleaved and the end is severed. The ferrule is polished to remove the pedestal, resulting in a smoothly polished end surface.

An apparatus for injection molding of a fiber optic ferrule including the use of adjustable core and receiver members to precisely locate a core pin and also a projecting wire member in a mold where the core pin defines an interior passage in the molded ferrule and the projecting wire forms a small diameter longitudinal hole in the ferrule communicating with an outer end of the interior passage so that the interior passage and small diameter hole are precisely located relative to the body of the molded ferrule.

A method and apparatus for injection molding of a fiber optic ferrule including the use of adjustable core and receiver members adjustable from the exterior of the mold to precisely locate a projecting wire member in a mold where a score pin defines an interior passage in the molded ferrule and the projecting wire forms a small diameter longitudinal hole in the ferrule communicating with an outer end of the interior passage so that the interior passage and small diameter hole are precisely located relative to the body of the molded ferrule.
摘要:
MT ferrule. A polymer fiber optic MT ferrule includes hermaphroditic L-shaped halves having multiple fibers mounted in V-grooves formed within surfaces of ferrule halves. Ferrule halves include holed walls perpendicular to the major surface of the V-grooves for providing alignment of the ferrule to guide pins of an MT receptacle having an alignment assembly and an alignment member mounted within the alignment assembly to provide for precision alignment.
摘要:
A massive parallel (MP) connector is provided which includes a fiber optic connector having a polymer ferrule having multiple fibers mounted in V-grooves of the ferrule and beveled edges of the ferrule providing for alignment of the ferrule when the MP fiber optic connector is mated to a receptacle having an alignment assembly and an alignment member mounted within the alignment assembly to provide for precision alignment. A receptacle assembly is provided having a first receptacle half for receiving a fiber optic connector having a first form factor and a second receptacle half for receiving a fiber optic connector having a second form factor.

A massive parallel (MP) connector is provided which includes a fiber optic connector having a polymer female having multiple fibers mounted in V-grooves of the ferrule and beveled edges of the ferrule providing for alignment of the ferrule when the MP fiber optic connector is mated to a receptacle having an alignment assembly and an alignment member mounted within the alignment assembly to provide for precision alignment. A receptacle assembly is provided having a first receptacle half for receiving a fiber optic connector having a first form factor and a second receptacle half for receiving a fiber optic connector having a second form factor. A fiber optical ferrule is also provided having a pair of mutually opposing ferrule halves that join to define a fiber optical support region that receives optical fibers, where at least one of the ferrule halves includes a vertically aligned wall that protrudes towards the opposing ferrule half, and the ferrule half contains a beveled edge for aligning the fiber optical ferrule within a receptacle for optical connection with another connector.
摘要:
A polishing apparatus is provided for holding at least one fiber optic connector ferrule in an upright position while allowing the face portion the ferrules to be held firmly against a planar sheet of ferrule polishing paper. The apparatus can be manually maneuvered over said polishing paper thereby polishing the face portion of the ferrules inserted therein. The polishing apparatus includes a disc having a polishing surface and an upper surface opposite said polishing surface. A plurality of ferrule receiving apertures are formed in the disc for receiving various connector ferrules. Support skirts surround each aperture, extending upward from said upper surface. The ferrule support skirts define internal circular bores communicating with the polishing surface such that fiber optic connector ferrules may be inserted into the bores with the face portion of said ferrules extending beyond said polishing surface. A grasping ring is integrally molded with the disc and provides a means by which a technician can grasp the apparatus and maneuver the apparatus over a piece of polishing paper. Tooling support members are integrally formed with the grasping ring and are configured to accept tooling support shaft extending from a holddown tool designed to apply a normal force against the ferrules to firmly hold them against the polishing paper. Wear resistant surfaces in the form of hardened spheres protrude slightly from cavities formed in the polishing surface of the apparatus to protect the polishing surface from abrasive action of the polishing paper.
