  • Publication number: 20100183265
    Abstract: Termination systems and devices disclosed herein use a handler that attaches to the optical fiber or cable and cooperates with other components for preparing the optical fiber and/or making the optical connection, thereby providing a simple, reliable, and easy termination for the optical fiber. For instance, the handler may cooperate with one or more of the following a strip tool, strip/clean tool, cleave tool for preparing the end of the optical fiber(s), and/or a connector-to-handler adapter for making the optical connection.

  • Patent number: 7658553
    Abstract: A mechanical splice connector is shown and described for sequentially performing a splice actuation followed by a strain relief actuation by rotating a single, multiple-position cam member or multiple cam members from an unactuated position to a first actuated position and a second actuated position. The mechanical splice connector aligns and retains at least one stub optical fiber and the bare glass portion of at least one adjoining field optical fiber, as well as strain relieving a coated portion of the field optical fiber, or alternatively, a buffered portion of the field optical fiber. A method is also described for sequentially performing a splice actuation followed by a strain relief actuation, wherein the splice actuation is reversible prior to performing the strain relief actuation in the event that the optical continuity of the splice coupling is unacceptable, thereby avoiding potential damage to the field optical fiber or the connector.

  • Patent number: 7512308
    Abstract: The present invention addresses the need for a stress relieving device and protective jacket for exposed fiber within a field-installed optical network enclosure, such as a network interface device. The present invention incorporates a furcation tube coupled with a furcation body. The coupling may be accomplished by a direct connection or with use of an external or internal transition body. The present invention enables a field-installer to transition an optical fiber cable from the field into a furcation tube thereby providing a means for attaching an optical connector, such as a mechanical splice connector, onto the optical fiber and furcation tube.

  • Publication number: 20080044144
    Abstract: A fiber optic mechanical splice connector including a single connector element operable for providing optical fiber alignment and strain relief includes opposed splice components that define first and second grooves for receiving the bare glass portions of mating optical fibers, as well as the coated or buffered portion of at least one of the optical fibers when the splice components are biased together by an actuator. The mating optical fibers are aligned while the coated or buffered portion of one of the optical fibers is retained within the same connector element, thus eliminating positioning problems that occur when separate connector elements are utilized for fiber alignment and strain relief. The splice components may be unbiased to allow removal of at least one of the mating optical fibers without destroying the connector assembly or potentially damaging the optical fibers.

  • Patent number: 7204644
    Abstract: A field installable fiber optic connector includes a housing and a ferrule holder inserted from the rearward end of the housing. A spring element inserted into the front of the housing and a spring element retainer attached to the ferrule holder bias the ferrule holder forward. An optical fiber stub is disposed between opposed splice members and a field fiber is inserted between the splice members and guided by a groove into abutment with the end of the optical fiber stub. A cam disposed about the ferrule holder is movable to facilitate insertion of the field fiber and to clamp the field fiber and the optical fiber stub between the splice members. In one embodiment, a trigger is coupled to the housing. The trigger is disposed about and slides relative to the ferrule holder, thereby biasing the housing forward relative to the ferrule holder to aid in latching the connector.

  • Publication number: 20050238292
    Abstract: A field installable optical fiber connector includes a connector housing, a ferrule, a ferrule holder, a splice holder, splice components and a cam member. The splice holder is disposed within the connector housing and defines a first cavity adjacent the forward end and a second cavity adjacent the rearward end. The ferrule holder is fixedly disposed within the first cavity and defines a recess adjacent the forward end. The ferrule is fixedly disposed within the recess and defines a longitudinal bore for receiving an optical fiber stub. The splice components are disposed within the second cavity and configured to receive and secure the optical fiber stub to a field fiber when the cam member disposed about the splice holder is actuated. The splice holder is made of a plastic material and the ferrule holder is made of a metal material to simultaneously satisfy cost, capacity, geometry, strength and machining requirements.

  • Patent number: 6931193
    Abstract: Methods are provided for validating the continuity of one or more optical fibers upon which a fiber optic connector is mounted. Typically, the fiber optic connector is mounted upon an optical field fiber by actuating a cam mechanism to secure the optical field fiber in position relative to an optical fiber stub. If subsequent testing indicates that the continuity of the optical field fiber and the optical fiber stub is unacceptable, the cam mechanism can be deactuated, the optical field fiber can be repositioned and the cam mechanism can be reactuated without having to remove and replace the fiber optic connector.

  • Patent number: 6585421
    Abstract: A spacer is provided to assist in orienting and aligning optical fibers in a connector. The spacer may also provide strain relief for the optical fibers. The spacer is especially useful with smaller optical fibers that are to be used in connectors that are designed for larger optical fibers or cables. Openings extending through the spacer, which may have a channel that allows for communication between the openings. The spacer can have as many openings as there are fibers for the connector. The spacer also assists in holding the fibers during the cleaving process so that the fibers are cleaved simultaneously and consistently.

  • Publication number: 20030027497
    Abstract: A polishing fixture and method suitable for use with springless fiber optic connectors, as well as connectors with integrated springs, is provided. The polishing fixture comprises at least a base plate and a plurality of connector assemblies. Each connector assembly includes a spring and the movement of the connector against the force of the spring applies a spring force to the connector during polishing to compensate for the variation of the protrusion of the connector and optical fiber below the base plate of the polishing fixture. The polishing fixture of this invention can be used with circular and non-circular shaped connectors and with single and multi-fiber connectors.
