Abstract: A high-density, small fiber optic enclosure permits the cross-connection and interconnection of optical fibers, through the use of an open-faced compact layering technique. The optical fiber enters an aperture in the bottom of the enclosure which includes a first section attachable to a wall surface, and a second section connected to the first enclosure section by a hinge. The first enclosure section includes an optical fiber splice holder and a plurality of hooks and clips for holding the optical fibers. The second enclosure section includes a plurality of hooks and clips also. The fibers enter the first section, are connected to the hooks and clips, and cross over to the second section and return to the first section and ultimately pass through an exit aperture in such a fashion as to form a plurality of FIG. 8 layers. If the optical fibers are not shielded, it is possible to use two opposing S-shaped fiber tubes to protect them at the crossover between the first and second enclosure.

Abstract: In accordance with the invention, a preform from which fiber optics are drawn is fabricated by supplying reactants and gas vapors to the preform and by using two opposing forces to control the movement of a heat source supplying heat to the preform. The two forces function to reduce any hesitation or backlash in the movement of the heat source along predetermined portions of the preform to enable uniform layers to be formed within the preform.

The electrical contact has a bifurcated end for engaging and retaining the wire and is engaged with the strain relief cap in securing the wire. The cap attaches to the contact via means on the electrical contact for engaging both the cap and the wire. The wire is secured by placing cap onto the contact, aligning the wire with exit holes, and turning cap until locked into place.

Abstract: Apparatus embodying the invention includes first and second motors coupled to a carriage assembly for moving the carriage assembly back and forth between first and second end points. The first motor is for developing a force to drive the carriage in one direction and the second motor is for developing a force to drive the carriage in an opposite, second direction. When the first motor causes the movement of the carriage in one direction, the slowing, stopping and reversal of the carriage is achieved by varying the power supplied to the second motor relative to the power supplied to the first motor until the force exerted by the second motor first equals and then exceeds the force exerted by the second motor. So operated, the carriage motion is well controlled and exhibits little, if any, backlash.

Abstract: An assembly includes an enclosure and a device for storing fiber slack. The device has a pair of spool portions on opposite sides of the device. Each spool portion is shaped so that fiber slack can be wound back and forth between the two spool portions. The device is pivotally mounted within the enclosure, so that the pair of spool portions can be accessed by pivoting the device. Each spool portion may have a semicircular shape. Each spool portion has a radius at least as large as a minimum bend radius for a fiber to be stored on the device. A length of a fiber portion extending between the pair of spool portions is substantially greater than a perimeter of one of the spool portions. The device has top and bottom U-shaped channels connecting the tops and bottoms of the spool portions, respectively. The pair of spool portions and the top and bottom U-shaped channels form an elongated spool for storing fiber, the elongated spool extending around three sides of the device.
