  • Patent number: 8229261
    Abstract: Optical splitter assemblies are provided. An assembly may include a housing, one or more fanout elements, an optical splitter element, an input fiber and a plurality of output fibers. The input fiber extends from an input opening of the housing to the optical splitter element. The input fiber carries an input signal to the optical splitter element and the optical splitter element splits the input signal into a plurality of output signals to be carried by the plurality of output fibers. Each of the output fibers extends from the optical splitter element to beyond a plurality of output openings of the housing. Each of the fanout elements defines one or more channels for supporting the input or output fibers. The assembly may further include tubular members for further support to the fibers. The fibers extend from the openings of the housing to the optical splitter element free of any loops.

  • Patent number: 7738758
    Abstract: A device may include an input cable for receiving optical signals from a feeder cable, output cables for transmitting optical signals to a distribution cable, and a housing. The housing may include an optical splitter for splitting an input beam into a plurality of output beams, an input fiber segment for conveying the input beam from the input cable to the optical splitter, the input fiber segment excluding fiber loop slack, and output fiber segments for conveying the output beams from the optical splitter to the output cables using MT-APC connectors.

  • Publication number: 20100142888
    Abstract: A device may provide a first opening via which a feeder optical fiber cable that carries an input signal enters the device. In addition, the device may include a slot configured to retain a splitter module. The splitter module may include a single-fiber input cable that receives and carries the input signal from the feeder optical fiber cable, an optical splitter that receives the input signal from the single-fiber input cable, splits the input signal into a plurality of output signals, and transmits each of the plurality of output signals, and a multi-fiber output cable that receives the plurality of output signals from the optical splitter and carries the plurality of output signals. The device may also provide a second opening via which a multi-fiber distribution cable that receives the plurality of output signals from the multi-fiber output cable exits the device. The multi-fiber distribution cable may carry the plurality of output signals.

  • Publication number: 20080152290
    Abstract: A fiber distribution hub assembly is provided. The assembly may include a housing, one or more optical splitter devices, and an optical patch panel. The housing may define an interior area for storing the optical splitter devices and the optical patch panel. The optical splitter device is configured to receive an input optical fiber carrying an optical signal and split the optical signal among multiple output optical fibers. The optical patch panel includes a plurality of LC adapters that are in communication with distribution cables leading to different elements of a network. The LC adapters of the optical patch panel are configured to receive LC plugs attached to the ends of output optical fibers. A particular optical signal can be sent to a particular element of the network by connecting the appropriate output optical fiber to the LC adapter in communication with that element via a respective distribution cable.
