  • Publication number: 20030231849
    Abstract: A fiber optic cable closure for containing optical fibers of a dispersion-managed network. The fiber optic closure has a housing with a cavity, and at least one bridge optical fiber disposed within the cavity. The bridge optical fiber having a first end configured to optically connect to a first optical fiber with a first dispersion characteristic. A second end of the bridge optical fiber is configured to optically connect with a second optical fiber having a second dispersion characteristic. In one embodiment, the fiber optic cable closure includes a fiber optic cassette within the cavity of the housing when assembled.

  • Patent number: 6542688
    Abstract: A fiber optic closure includes a panel assembly having at least two planar panels affixed to another in a hinged manner. The panel assembly includes a storage bay sandwiched between a pair of fiber connection management assemblies. Each fiber connection management assembly includes a sleeve connector panel that supports one or more sleeve connector arrays within which fiber optic cable connectors may be inserted to establish fiber optic connections. The panel assembly also provides a conventional splice panel having splice holders within which splice connections are established. It is preferred to position the splice panel directly adjoining the sleeve connector panel. In this manner, a craftsperson can easily form custom sleeve connections within the fiber optic closure by splicing connectors onto selected optical fibers utilizing the splice panel and then interconnecting the connectors with opposing connectors utilizing the sleeve connector panel.

  • Patent number: 6539160
    Abstract: A fiber optic closure includes a panel assembly having at least two panels hinged to one another. The panel assembly includes a storage bay sandwiched between a pair of fiber management and connection assemblies. Each fiber management and connection assembly includes a sleeve connector panel that supports at least one sleeve connector array for establishing optical fiber connections. The splice panel having splice tube holders is also provided for establishing splices. The splice panel may further have at least one coupler cassette for splitting at least one input optical fiber into two or more output optical fibers. Preferably, the splice panel is positioned adjacent the sleeve connector panel so that a craftsperson can easily form custom sleeve connections within the fiber optic closure utilizing the splice panel to splice connectors onto selected optical fibers and utilizing the sleeve connector panel to interconnecting the connectors with opposing connectors.

  • Patent number: 6466725
    Abstract: An apparatus and method for splitting or otherwise separating and routing optical fibers are provided in which a splitter housing having first and second separable halves is mounted upon a plurality of optical fibers without having to cut all of the optical fibers. The splitter housing generally includes an inline portion and a branch portion. The inline portion defines an input port at one end for receiving a plurality of optical fibers and a primary output port at the opposed end through which at least one optical fiber exits. The branch portion extends outwardly from the inline portion at one end and defines a secondary output port at the opposed end. The branch portion is in communication with the inline portion such that at least one optical fiber that enters through the input port can be separated from the remainder of the optical fibers and routed through the branch portion.

  • Patent number: 6421494
    Abstract: An apparatus is provided for strain relieving a communications cable having a non-cylindrical cross section and for optimally positioning a plurality of the cables. The apparatus includes at least two plates oriented adjacent one another. Each of the plates has at least one mounting surface and at least one strain relief surface. The strain relief surface may be angled relative to the mounting surface. At least one fastener draws the plates together to grip the cable between the strain relief surfaces. The apparatus may further include a plurality of laterally extending teeth depending from the strain relief surface of at least one of the plates. The teeth increase the gripping force applied to the cable. The cable may have an electrically conductive inner sheath that is pierced by the teeth on the strain relief surface and the apparatus may be further provided with a ground strap for grounding the cable.

  • Patent number: 4589420
    Abstract: A method and apparatus for automatic rhythm analysis of digitized ECG signals. Candidate heartbeats are detected and the noise of the ECG signal portion containing the candidate is evaluated to determine whether the candidate is a valid nominal or noisy beat or an invalid noisy saturated signal. The timing of detected heartbeats, both noisy and nominal, are determined relative to prior validated heartbeats. Features of the detected heartbeats are automatically extracted including onset, offset and R wave locations; QRS complex width; R-R interval based on the onset points; instantaneous and averaged heartrates; and others. A 16 point template of the heartbeat starting at the onset is also determined. Beats are then classified in a two step process; first, by template comparison with a previously determined dominant template, and second, by a finite state machine process based on the results of the template comparison and relative timing of the beat.
