  • Patent number: 7785019
    Abstract: There is provided a fiber optic receptacle and plug assembly adapted to provide electrical connectors for electrical conductors. The receptacle and plug define complimentary alignment and keying features for ensuring that the plug is mated with the receptacle in a predetermined orientation. An alignment sleeve is disposed within the plug for receiving a multi-fiber receptacle ferrule and a multi-fiber plug ferrule. The fiber optic receptacle and corresponding plug each include a biasing member assembly for urging the receptacle ferrule and the plug ferrule towards one another, wherein the biasing member assembly includes a spring, a spring centering cuff and a ferrule boot that operatively engage the rear of the receptacle ferrule and the plug ferrule, respectively, to substantially center a spring biasing force on the end face of the receptacle ferrule and the plug ferrule. The electrical connectors of the receptacle and plug are preferably provided separate from the biasing member assembly.

  • Patent number: 7658549
    Abstract: A pre-connectorized fiber optic distribution cable assembly includes a plurality of optical fibers and at least one mid-span access location along the length of the distribution cable. At least one of the optical fibers is accessed, terminated and then connectorized at the mid-span access location to an optical connector disposed within a receptacle. The mid-span access location, the accessed, terminated and connectorized optical fiber, the optical connector and at least a portion of the receptacle are encapsulated with a protective overmolded shell. A tether including at least one optical fiber connectorized at a first end of the tether is optically connected to the optical connector through the receptacle. A second end of the tether opposite the first end terminates in a network optical connection terminal, thereby compensating for a span length measurement difference between the actual location of the mid-span access and the desired location of the optical connection terminal.
