  • Patent number: 5329604
    Abstract: An optoelectronic system including an optoelectronic assembly for receiving and/or transmitting optical data signals, optic means for being optically coupled to the optoelectronic assembly, and an optical fiber coupling device for coupling the optic means and at least one of the optoelectronic devices which form part of the assembly. The coupling device includes a housing for being positioned adjacent the assembly relative to the optoelectronic device and, significantly, latching means movably positioned within the housing for initially engaging the optoelectronic device and thereafter for engaging the incoming optic means (e.g., optical fiber connector) when the optic means is positioned within the coupling device's housing. Keying and shutter means are also provided as part of the coupling device.

  • Patent number: 5315679
    Abstract: An optical fiber duplex connector assembly wherein two individual optical fiber connectors are positioned and retained within a common housing, such that relative freedom of movement between the two connectors within the common housing facilitates positioning of the retained two connectors within a suitable receiving common housing (e.g., shroud). Such movement accomodates for manufacturing tolerances within the housing and/or connectors while still assuring successful insertion. A housing, having two chambers (one for each connector) and a cover assures the defined movable connector positioning while also providing effective retention. A boot may be attached to the housing to accomodate for severe bends and turns of the optical fiber cable, without loss of attenuation.
