  • Patent number: 4708430
    Abstract: A cable terminating cabinet for terminating optical waveguide cables contains an array of optical waveguide connectors one side of each connector having a pigtail fiber attached to it, the pigtail fibers being spliced to waveguides of a cable terminated at the cabinet. Waveguides terminating at the other side of the connector are taken to electro-optic units where optical signals within the fibers are converted into corresponding electrical signals. The cabinets find application either at a central office cable terminating frame or in a test access unit at a location remote from the central office. The connectors are mounted in a panel which is exposed when a front cover of the cabinet is removed, the panel being pivoted about a vertically orientated hinge to expose a stacked set of splice organizing trays at the rear of the cabinet. Ready access is therefore possible to both the connector panel and the splice organizing trays.

  • Patent number: 4660125
    Abstract: A ribbon cable assembly for interconnection to an electronic equipment pull-out drawer which is arranged so as to occupy a minimum of depth within the drawer while effectively preventing kinking or tangling of the cables as the drawer is opened and closed. This is achieved by folding each of the cables back on themselves so that they individually connect to the back of the drawer at different elevations at connections which are in vertical alignment with one another. In addition the cables overlie each other so that their flat surfaces are orthogonal to the direction of movement of the pull-out drawer.
