  • Patent number: 6848834
    Abstract: A fiber optic connector is provided having translating termini, such that the terminal end of the termini will extend out of the forward end of an insert cap to prevent mud or debris from becoming lodged within the bores of the insert and within alignment sleeves which are contained within the insert cap. The fiber optic cable connector preferably is provided with continuous ceramic sleeves to align the adjacent termini of optical fibers included within respective ones of the cables. The continuous ceramic sleeves have internal bores which are slightly larger than the outside diameter of the periphery of the termini, providing a clearance fit between the continuous ceramic sleeves and respective ones of the termini. The termini are independently gimbaled, with gimbal points being disposed distally from respective mating planes between opposing terminal ends of the termini.

  • Patent number: 6648521
    Abstract: A fiber optic connector has a preterminated fiber mounted within a ferrule and a fiber guide tube for guiding a terminating fiber into the ferrule to optically coupled the terminating fiber to the preterminated fiber, with an index matching gel extending between the terminating fiber and the preterminated fiber. An index matching gel is initially disposed on an end face of the preterminated fiber and inside of the fiber guide tube. The index matching gel is placed on an end face of the terminating fiber by passing the terminating fiber through the fiber guide tube, with a portion of the gel being wiped free of the terminating fiber periphery as the fiber enters the ferrule. A window extends through a sidewall of the fiber guide tube for applying an adhesive to secure the terminating fiber to the connector.

  • Patent number: 6394661
    Abstract: A multi-channel fiber optic connector is provided having a plug connector half and a receptacle connector half. The plug and the receptacle have respective inserts that include exterior peripheries of a particular shape for mating with an interior profile of a housing of the receptacle. The peripheries of the inserts are preferably defined by cylindrical bodies having respective tabs which protrude outward from the outer diameters of the inserts. The interior profile of the receptacle housing defines a recess for receiving the tabs to both angularly align the insert associated with the receptacle and to angularly align the insert associated with the plug. The recess in the receptacle housing is defined by a groove which extends parallel to the longitudinal length of the receptacle housing, with the same groove receiving the protuberant tabs of both inserts to angularly align the inserts. The inserts have fiber optic termini mounted therein.
