  • Patent number: 6318902
    Abstract: A fiber optic connector having improved alignment and manufacturing characteristics over traditional connectors. A fiber optic connector of the present invention has a first connector ferrule and alignment means for aligning the first connector ferrule with a matching second connector ferrule. The fiber optic connector includes a first connector ferrule including a first mating surface. The mating surface defines at least one receiving cavity, and at least one protruding alignment rod is seated in the cavity and extends from the mating surface. The alignment rod has a diameter D1 and protrudes from the mating surface a protrusion distance p1, wherein p1≦2D1. In an exemplary embodiment the rod has a spherical tip and 0.5D1≦p1≦2D1.

  • Patent number: 5889910
    Abstract: A control jacket houses a line, such as a fiber optic ribbon cable or other conductor, and limits the amount of bending and twisting movement of the line. The jacket preferably includes a multi-dimensional matrix of engagement elements separated by a plurality of gaps and connected by an underlying web structure. As the jacket is bent or twisted, adjacent engagement elements move together into engagement with each other, limiting the bend radius or twist angle of the jacket, and thus of the fiber optic ribbon cable or other protected line. The jacket preferably includes at least one fastening mechanism, allowing the control jacket to be opened along its length for easy insertion and removal of the line as needed. Multiple jackets can be placed end-to-end along the line, to create a composite jacket of any desired length. Additionally, a control jacket according to the invention includes two slideable jacket portions.

  • Patent number: 5757997
    Abstract: A fiber optic connector comprising a plug and a receptacle uses the spring force supplied by bowing of the plug fiber to maintain a continuous compressive load at the fiber joint located in a fiber-alignment groove. The plug has a holder for securing the plug fiber and a shroud which snaps onto the holder with the plug fiber extending generally straight inside the shroud. The shroud has a slot providing access to the terminal portion of the plug fiber, and a sliding door which selectively covers the slot. The receptacle includes a housing and another fiber holder for securing the receptacle fiber, with a projection or finger attached to the receptacle fiber holder, the projection having the fiber-alignment groove. The finger is oriented within the receptacle housing such that, when the plug is inserted into the receptacle, the finger extends through the slot in the shroud at an oblique angle with respect to the plug axis.

  • Patent number: 5611017
    Abstract: A fiber optic ribbon cable has release elements manufactured in line with the ribbon cable so as to provide access points to the optical fibers contained therein to allow for easy application of a connector in the field. A pair of adhesive tape layers is provided about the optical fibers to create a fiber optic ribbon cable. At least one release element is provided between the adhesive tape layers and the optical fibers at one or more access points along the ribbon cable to allow for subsequent connectorization of the fibers therein. When the ribbon cable needs to be equipped with a connector, the cable is cut near the midpoint of one of the access point. After the cable is cut the adhesive tape layers and the at least one release element may be easily peeled back exposing the optical fibers. A connector is then installed onto the exposed fibers. The at least one release element is removed from the tape layers and the tape is then secured to the connector with any excess tape being trimmed off.

  • Patent number: 5574817
    Abstract: A fiber optic ribbon cable assembly has optical connector assemblies manufactured in line with the ribbon cable assembly so as to provide a fixed, lateral spacing of the optical fibers relative to each other within the connector assembly and has the remaining portion of the fiber optic ribbon cable manufactured within an arbitrary lateral spacing of the optical fibers relative to each other. A pair of adhesive tape layers are sandwiched around the optical fibers and the in-line optical connector assemblies. By having the connector assemblies manufactured in line with the fiber optic ribbon cable, resulting ribbon cable assembly is easier to manufacture, has a higher alignment accuracy, and is more cost effective than existing techniques for manufacturing ribbon cable assemblies.
