  • Publication number: 20140363128
    Abstract: A multi-pin connector with a small envelop and low insertion loss capable of operating while submerged is described within. This configuration avoids the tolerance stack up troubles that has plagued other similar designs thereby allowing it to achieve a low insertion loss without the typical cost drivers of tighter tolerances. In addition this invention incorporates as relatively simple method of tuning each pair of connectors thereby further reducing the insertion loss for each matched pair.

    Abstract: A fiber optic connector includes a housing and a locking member. The housing has a longitudinal passage extending between a first opening at a first end of the housing and a second opening at a second end of the housing, the housing sized to fit within a fiber optic receptacle. The locking member is a separate part from the housing and is sized to fit within a retaining notch in the fiber optic receptacle. The locking member, when secured to the housing and located in the retaining notch, interfaces with the retaining notch to prevent separation of the housing from the receptacle.

  • Patent number: 8678667
    Abstract: In an optical connector, end faces of a pair of ferrules that hold multiple optical fibers are positioned with two guide pins and butted against each other to connect the optical fibers in the pair of ferrules. The optical connector is provided with an urging member for pushing the end faces against each other. The end faces are ground at an angle. The gap between the guide pins and guide holes, which open at the end faces and into which the guide pins are fitted, is larger than 0.004 mm and smaller than or equal to 0.008 mm. Powder caused by the friction generated when the guide pins are inserted and fitted into the guide holes is greatly reduced. Connection loss does not increase even when frequent connection and disconnection are performed, and cleaning the connector becomes unnecessary.

  • Publication number: 20140056560
    Abstract: Systems and methods are provided that enable a first bank, or array, of multi-optical fiber connector modules disposed in a plug that is mounted on a first structure to be simultaneously blind mated with a second bank of multi-optical fiber connector modules disposed on a receptacle that is mounted on a second structure. As the first and second structures are brought into engagement with one another, passive coarse alignment features on the plug and on the receptacle coarsely align the respective connector modules with one another. Then, as the respective connector modules begin to come into contact with one another, passive fine alignment features on the respective connector modules engage one another to finely align the respective connector modules such that their optical pathways are brought into precise optical alignment with one another.

    Abstract: A method of manufacturing an optical cable including plural waveguides each including plural optical channels and each of the waveguides and the optical channels having a first end and a second end. A central portion of each of the waveguides is displaced along a central longitudinal axis of the waveguides which traverses a central bifurcation line of the first and second connectors. A first optical channel connection pattern is formed on the first connector by the first ends of the optical channels of the waveguides connected thereto; and a second optical channel connection pattern formed on the second connector by the second ends of the optical channels of the waveguides connect to the second connector. The first optical channel connection pattern is a different pattern than the second optical channel connection pattern in relation to a connection hole pattern which is the same for both the first and second connectors.

  • Publication number: 20130322825
    Abstract: A multi-fiber fiber optic connector is configured to include a switchable polarity key that can be used to define first and second polarity configurations for the connector. The connector has a multi-fiber ferrule surrounded by an inner housing. The inner housing has top and bottom recesses sized to accommodate the polarity key. The polarity key is removably secured in either a top or bottom recess using a latching feature. The polarity of the connector can be switched by moving the polarity key from one position in the connector to the other rather than having to disassemble the connector.

    Abstract: An apparatus includes a connector that connects to optical fibers for connecting first and second optical signals to the apparatus. A first optical ferrule is mounted perpendicularly to the connector, and transfers the first optical signals between the connector and first optical transducers mounted on a first substrate, via first holes formed in the first substrate. A second optical ferrule is mounted perpendicularly to the connector, and transfers the second optical signals between the connector and second optical transducers mounted on a second substrate, via second holes formed in the second substrate. A light rotation module bends and transfers the first and second optical signals between the connector and the first and second ferrules. One or more lenses are mounted between the first ferrule and the first holes, so as to couple the first optical signals via the first holes between the first ferrule and the first optical transducers.

    Abstract: A fiber optic link connection system facilitates connection between two arrays of optical fibers. Two female-type connector plugs, each attached to a respective end of two fiber optic arrays, are inserted into the open ends of a connector guide sleeve. Two guide pins are captured by intrusions within the guide sleeve in order to mate with and align the two plugs. Guide capture pins and associated springs are disposed within the guide pin intrusions to capture the guide pins. Such an arrangement not only protects the guide pins from damage, but also promotes connector compatibility.
