    摘要: Optical fiber and cable management apparatus includes a base for mounting on a wall or other surface at a subscriber premises, and a drum region extending axially upward from the base. The drum region includes an outer cylindrical wall for supporting a length of a first fiber optic cable wound about the outer wall, an inner cylindrical wall disposed radially inward of the outer wall to define an annular fiber routing region between the two walls, and a cable entry port in the outer wall for receiving an end portion of the first fiber optic cable so that fibers of the cable may be routed through the fiber routing region. An interface compartment disposed atop the drum is constructed to interface a first set of fibers routed within the compartment, with a second set of fibers associated with a second fiber optic cable that is routed to the apparatus.

    摘要: Embodiments of the invention include an apparatus and system for managing and radially distributing optical fibers from a first location, such as a central office, to a plurality of destination locations, such as homes within a neighborhood. The apparatus includes a distribution panel having a central hub or ring, and both a plurality of optical input elements and a plurality of optical output elements disposed radially around the central hub. The optical input elements split the fibers coupled from the first location into a plurality of individual fibers that are routed to the central hub. The central hub radially distributes the plurality of fibers to appropriate optical output elements, which are coupled to destination fibers routed to the plurality of destination locations. The radial configuration of the apparatus provides a central breakout point for fiber distribution, thus improving fiber organization and routing management compared to conventional routing and distribution systems.

    摘要: In one embodiment the present invention includes a method for starting up a class D amplifier. The method comprises increasing, gating, and driving. The increasing includes increasing a duty cycle of a pulse train from a first duty cycle to a second duty cycle. The gating includes gating a signal based on the increasing of the duty cycle. The gating results in a gated signal. The driving includes driving an output signal from the gated signal to charge an output capacitor. The output capacitor is coupled to a speaker. The increasing of the duty cycle contributes to the charging of the output capacitor such that switching sounds detectable by the human ear are reduced.

    摘要: A spooling tool for paying out a fiber optic cable prewound on a spool region of a drop box or on an associated spool, when installing a cable at a user's premises. In one embodiment, the tool includes a base plate and a stud projecting from one side of the plate. An elongate arbor has one end secured to the stud in such a manner as to support the arbor perpendicular to the base plate. The arbor is dimensioned to pass through an axial passage in the box so that the box pivots on the arbor when the cable is unwound by an installer. A cap mechanism at the opposite end of the arbor retains the drop box on the arbor, and applies enough drag on the box to inhibit it from free wheeling on the arbor.
