  • Publication number: 20100284656
    Abstract: A connector that enables fiber optic cables to terminate at equipment in cabinets having little space available for cable routing, without over bending. The construction includes a connector housing, and a yoke including a collar joined to a rear end of the housing. A tubular cable bend limiter is fixed at one end to the collar and the limiter directs a cable containing one or more bend insensitive fibers through a bend of, e.g., 90 degrees, between the collar and the opposite end of the limiter with a fiber bend radius of less than one inch (25.4 mm). If the limiter creates a fiber bend radius of 0.300 inch (7.62 mm), the distance between the front of the connector and the cable after bending may be as little as 1.26 inches (32 mm), allowing the cable and connector to be routed and terminated in limited space without impairing performance.

  • Patent number: 7614799
    Abstract: Embodiments of the invention include a hardened connector system. The connector system includes a connector plug for terminating an optical fiber, a plug housing for coupling to the optical fiber cable and the connector plug, and a translator for coupling the plug housing and the connector plug to an optical fiber connector adapter. The translator, which couples the plug housing to a jack receptacle portion of the connector adapter is configured to allow the connector to be decoupled from the connector adapter without damaging the connector adapter, e.g., when the connector system is subjected to relatively excessive cable loads. Also, the dimensions and configuration of the plug housing allow it to be pulled through conventional conduit, including a 90°-bent, 0.75 inch Schedule 40 conduit.

  • Patent number: 6234685
    Abstract: The present invention provides a fiber optic connector and a method for installing a fiber optic connector including a barrel assembly disposed within a housing. The barrel assembly includes a barrel being formed of deformable material and having a barrel body and a barrel extension extending from an end of the barrel body. An opposing end of the barrel body supports a ferrule having a pre-polished fiber stub disposed therein. An insert is disposed within the barrel, the insert being deformable and is arranged and configured to receive at least one fiber. An extender cap engages a portion of the housing fixing the barrel assembly within the housing. The housing includes at least one aperture disposed in a side portion for accessing the barrel assembly. In one aspect of the invention a method for installing a fiber optic connector is provided including the steps of, first, forming a barrel assembly.
